Scent Pendant

I know the title must sound odd, but this is actually a sappy, and in my opinion original gift idea for a female. Said female is significant. Need I say more? Anyways, I was wondering if there was a material that held a scent particularly well other than just normal fabric or something. Here's the idea: Have a pendant: small or large, really doesn't matter, that I can spray with my cologne, since she really enjoys it, it will hold the scent? ' This is just an idea, I did a little research to no avail, because I realized that this was just a little.. odd. XD Would really appreciate some fellow brainstormers. If worst comes to worst I was thinking I could actually take some of the cologne and have it in an intricate little glass vial and hang it from a pendant. Thanks all for your time and consideration, Roddie

Scented Candles

Hey guys. I'm paying my way through college and I'm trying to find a way to make a buck. I'm looking into making scented candles and I'm hoping i can get some answers. 1. How much would it cost to make one candle? (medium sized? 6 inches) 2. How much profit can I expect per candle? 3. Is it in demand enough to make a decent profit? I'll be selling small scale like craft shows and family friends. 4. How are fragrances made? I ask because I want to try some unusual scents. I've got ideas along the lines of freshly mowed grass, bacon, and apple pie. There's some far stranger ones but I need to know if this is even possible. How would i go about making these fragrances. 5. Where can I buy supplies cheaply? Obviously a higher margin for profit is better so I'd like to spend very little. Thanks in advance. Any other tips are helpful.

Spiral Scented Coasters

So recently at a garage sale, I found this really cool coaster.  It is shaped to a spiral, smells like vanilla, and is "activated" by heat.    I just really like the idea and I haven't been able to find anything anywhere on how to make them. I have found a couple instructables on how to make scented drink coasters, but not like the one I have.  I don't know if it would be the same general idea, just a different method of construction. I have found a couple places  selling the same thing that I have, but I'm sure you understand when I say, I'd rather make it myself if I can. The website I found, so you can get an idea of what I'm talking about:  http://www.littlecraftcottage.com/scentedcoasters.html Thanks in advance!

how to make a sprayable leather scent?

Many years ago I purchased an essential oils mixture from a small company that sadly is no longer in business.  This spay smelled exactly like leather, but I have no idea what the actual makeup was.  The closest thing I have found commercially is the leather scented air freshener from Yankee Candle.  Aside from running the inventory of a Wilson's Leather Store through a juicer, does anyone know a recipe for a leather scent?

Any recipes and tips for soapless/glycerineless personal grooming products? Multiple questions to follow...

Background to the problem: I have a big problem with fragrances and it's getting worse.  I've been able to find scent-free personal grooming products in the past, but the community I live in now has none!  Some of the local stores volunteered to special-order a few products, but were unable to find any from their vendors.  In other words, I am stuck with two choices.  Make my own or buy online. I am choosing to make my own, in order to save myself shipping cost and to be sure I don't have to wait 6-8 weeks to wash my hair.  The added benefit is knowing exactly what goes into it. The problem: I'm convinced I can do better than traditional soap.  I'm not scared of the lye and fats but I'd have to order all of the soapmaking stuff online, which still forces me to rely on the mail.  I'm very much intrigued by soapwort.  I've also heard of flaxseed-based hair wash.  From what I've heard, soapless alternatives present me with an option that's usually easier to produce and with locally available ingredients. What I already know is next-to-nothing.  I want all the tips and recipes I can find.  Most of what I've googled so-far has been 2-3 line "recipes" with only ingredients and no actual instruction on what to do with it or how to use it.  The only recipe I'm actually familiar with involves oil, lemon and an egg, for washing and conditioning hair but that doesn't keep well and it costs you an egg each time. The questions: Any recipes for interesting soapless, glycerineless "shampoos," body washes, hand "soaps," etc? Anyone know how of other cultures which use soapless products predominately and how they do it? Any good recipes for other personal items besides cleansers such as deodorant and moisturizer? Any tips for making these home-made products last longer in room-temperature storage? How do I reduce the costs but still keep my goal of being scent-free and soapless? I've never used flaxseed, will hair wash made from it have a strong smell?  Does it keep well? Can anyone using similar products tell me their experience with it?

Why are my essential oil scents disappearing from my Epsom salts?

I bagged (cellophane bags) and tied two pound bags of scented salts about 2 weeks ago and the scent has disappeared. Also, my food coloring doesn't mix well in the Epsom salts either.  For instance; red and blue is not making lavender color no matter how uch I increase or decrease the colors.

Refills for Reed Diffusers

My girlfriend buys reed diffusers from a company called West Elm for about twenty bucks apiece. When the scented oil eventually evaporates, she buys a complete new diffuser because the company does not sell refills. It would be great (and economical!) to be able to make our own scented oils to refill the bottles. I have seen cooking recipes on Instructables so maybe someone out there has a recipe for making scented oils. Thanks!

Do some spiders leave a scent trail ? Answered

 I didn't think so but a colleague told me of his recent experience; He was in the living room watching TV and a huge spider came in along the floor. He is scared of spiders and sat there transfixed. He said it was the biggest spider that  he had ever seen.  He and his partner squashed it, ( stupid humans), and threw it in the bin. The next day he was in the same place and a big, (but not as big ), spider came along and did the exact same route through the room. He said that it was a very unusual route to take but he knew that it was identical because he had studied both of them with absolute fear-based attention. So apart from making him feel guilty about killing the first one he wondered if spiders leave a scent. I can't find any answer on google so I'm asking anyone who may have knowledge of spiders? Thank you. I can't seem to find a suitable channel so I've chosen camping in the hope that some outdoor type will know.

How can I obtain cheap geosmin-scented air freshener?

What's the cheapest (safe and legal) way to obtain a small quantity of relatively pure geosmin? By "small" I mean an amount sufficient to keep a room smelling like rich earth for weeks. By "relatively pure" I mean it won't turn funky or give someone a nasty case of fungal pneumonia. Brew it? I know dehydration and alkali could -help- isolate Streptomyces, but then what? I don't have access to ready-made selective media nor money to buy strange supplies.

Anyone know how to make the Claire Burke Original fragrance oil for an effusion lamp?

I'm trying to locate "recipes" for a DIY effusion lamp oil. I found the basics-10-12 drops of essential oil per 16 oz. at least 91% alcohol, but some of these oils are expensive also. I'd like to recreate the Claire Burke Original scent-it, of course, has been discontinued.Any directions for the Applejack and Peel scent would be helpful too! I have the lamps, but the refill oils for all brands are really expensive;the alcohol can be found at drugstores and Wally-world for about $1.50/16 oz. bottle.The Essential oils are a bit more expensive, but all the info says one must use these-Not the fragrance oils. Apparently, those mixtures will clog the lamp wick or stone .Any and all suggestions for recipes and how many drops/Ml. of  the different oils-for ANY fragrances- will be welcomed.

Is there a cheap, easy way to fancify cheap hand soap?

I don't want to delve deeply into soapmaking. I just thought it would be easy to add sugar or salt (for that scrubby feeling) and old body spray (for scent) to my generic refill hand soap. But I've been playing around and I just wind up with completely unsuitable textures.  Basically it gets really runny and no matter how much sugar/salt I put in there, it doesn't flow through the dispenser so it doesn't get used.  Thanks.

Stray Cats Strut

Sad to say, a homeowner in the neighborhood takes no care of her cats and, of course, we had a bumper crop of strays for a while until nature and cars took care of most of them.  Two or three full-grown cats from the original litters are now quite healthy and roam our neighborhood freely.  As I have two indoor/outdoor cats, the "Wilds" have decided to take our yard as their own and you all know how cats mark their territory.  Every corner of our house, planters, and bbq has been sprayed as the battle for territory continues.  They're quite bold; I ran into one in our garage!  I'd like an effective, safe, non-painful (and entertaining, if possible) way to discourage them from coming into our yard and/or what I can spray over their spray to  nullify their scent.  (Baking soda and water mix, etc.)  I'm not home during the day to "catch" them in the act, I need something long-acting.  Thanks!

I have a question about making my own herbal extracts with alcohol, using fresh herbs...

I had a bunch of fresh herbs, and some home-distilled 180 proof alcohol that a friend brewed. SO, I thought I'd try to make some smelly stuff. I packed a jar with the fresh herbs, and filled it with the alcohol, plus a little tad bit of water. I let it sit for two weeks, and now it's ready to be strained. BUT, I'm not sure what to do with it. Do I use it to make a perfume, room spray, body spray? Can I use it to make an essential oil? Is what I now have called an herbal extract? One jar is fresh sage and rosemary, Jar 2 is rose geranium leaves and rose petals, Jar 3 is lemon verbena, and Jar 4 is lavendar and sage. All advice is welcome!

Challenge: design a water cannon for deterring cats

The Cats page (https://www.instructables.com/id/Cats/) incorrectly states that 'Everybody loves cats'.  In fact, everybody does NOT love cats, particularly those whose resent their tendency to massacre the wildlife in our gardens. I'd like to improve the odds of survival for all the birds, amphibians and small mammals in my garden, but without causing physical harm to the cats.  I've tried scent-based cat repellents without success, and I completely reject the idea of indiscriminate noise scarers. I can't police the garden 24/7, so my preferred solution is a water cannon capable of detecting a cat and soaking it. To keep things simple, I'd be thinking of using mains pressure to power the water jet, and batteries to power a motion sensor (infra-red). To be useful, the design would need to: - hit targets within a user-specified arc and at varying distances - allow the user to configure the sensitivity of the sensor, so that cat-sized heat sources are treated as targets, but smaller mammals are non-targets - avoid being triggered by foliage disturbed by the wind. For extra credit, the design could: - use solar power instead of batteries - focus the jet at the target, rather than spraying mist over a large area

One year old dog will not accept my new three month old puppy?

I have a one year old female husky mix (Nova). I rescued her from the pound when she was six months old. Nova loves women and children but has been afraid of men since I have had her. Nova is usually dog aggressive.. but not always. I thought that she would do well with a puppy. Clearly, I was wrong! I picked up a three month old female husky mix (Luna) two days ago. I allowed Nova to sniff Luna's scent on a jacket. Nova seemed extremely curious and even wagged her tail. I was impressed. I held Nova by her harness while we brought Luna into our house. Nova became extremely excited! Once Nova was calm I allowed her to sniff Luna out. As soon as Luna moved her head, Nova snapped at her face? Nova will follow her around the house standing stiffly and walking tall. I am unsure if this is to show she is dominant? Probably. If Luna tries to go anywhere as in near the fire place(where Nova lays every now and then), near my children or myself, Nova steps in front of Luna being territorial. Nova has snapped at Luna multiple times and has made Luna yelp. A few times Nova attempted to play with Luna by pawing at her, but she accidently hurt Luna. All of this is still going on along with now Nova is growling at Luna. I am afraid to let them "sort it out". What can I do to help Nova accept Luna?

Hanukah Candles (Left Overs)

Hey guys, I was wondering if a heat pad would work for melting wax. Since each year in Hanukah I use the left over wax to TRY and make candles. Here are the things I did. 2006: Used small tin foil molds. I didn't know how to make a wick then so I just used string. That was a FAILURE TOO. The string or so called wick didn't burn and just went to flames and didn't melt the wax and all it did was stay lit for 5 seconds. 2007: Kept wax and saved 2008: Kept wax and saved 2009: Used wax and try to put two blocks of wood together with a vice and drill a hole through the crack of both blocks of wood. It didn't work like I thought it would. The drill went all the way down the drill bit was atleast 5 in. long and it won't all the way down but when I poured the wax it didn't fill and over flowed. When I opened it up to try and see if there was a candle... well lets just say it turned out to be a half inch tall candle... and was about 1/5 of inch in diameter. I tried the to make a candle in a pot holder and forgot about the hole in the center then all the wax fell on the street and I didn't notice. It was such a pain to clean it off because it was on somebody elses lawn and I didn't want to mess up there lawn. WELL THAT WAS A FAILURE. 2010: This year I'm going to try to make scented candles. I'm going to use Tin Coke cans. I hope this works. I might use a heat pad since my mom doesn't want me to make wax in her cooking pans. If you have any suggestions send me E-MAILS at rexdino@sbcglobal.net or just post a message or private message me. I would prefer E-mail since I almost never check this website because I have about 20 other sites I have to check.

"Miracle Liquid" - Electrolyzed Water

Http://articles.latimes.com/2009/feb/23/business/fi-magicwater23I think someone with more time than me should see how to do this most efficiently and see if it work!The article:Sounds like the old "Saturday Night Live" gag for Shimmer, the faux floor polish plugged by Gilda Radner. But the elixir is real. It has been approved by U.S regulators. And it's starting to replace the toxic chemicals Americans use at home and on the job.The stuff is a simple mixture of table salt and tap water whose ions have been scrambled with an electric current. Researchers have dubbed it electrolyzed water -- hardly as catchy as Mr. Clean. But at the Sheraton Delfina in Santa Monica, some hotel workers are calling it el liquido milagroso -- the miracle liquid.That's as good a name as any for a substance that scientists say is powerful enough to kill anthrax spores without harming people or the environment.Used as a sanitizer for decades in Russia and Japan, it's slowly winning acceptance in the United States. A New York poultry processor uses it to kill salmonella on chicken carcasses. Minnesota grocery clerks spray sticky conveyors in the checkout lanes. Michigan jailers mop with electrolyzed water to keep potentially lethal cleaners out of the hands of inmates.In Santa Monica, the once-skeptical Sheraton housekeeping staff has ditched skin-chapping bleach and pungent ammonia for spray bottles filled with electrolyzed water to clean toilets and sinks."I didn't believe in it at first because it didn't have foam or any scent," said housekeeper Flor Corona. "But I can tell you it works. My rooms are clean."Management likes it too. The mixture costs less than a penny a gallon. It cuts down on employee injuries from chemicals. It reduces shipping costs and waste because hotel staffers prepare the elixir on site. And it's helping the Sheraton Delfina tout its environmental credentials to guests.The hotel's kitchen staff recently began disinfecting produce with electrolyzed water. They say the lettuce lasts longer. They're hoping to replace detergent in the dishwasher. Management figures the payback time for the $10,000 electrolysis machine will be less than a year."It's green. It saves money. And it's the right thing to do," said Glenn Epstein, executive assistant at the Sheraton Delfina. "It's almost like fantasy."

Handmade for the Holidays

The winter holidays are upon us!  I can't seem to go anywhere without being accosted in several senses at once with a frantic plea to "BUY, BUY, BUY!"  Advertisements for various sales splash across my field of view, blaring pop versions of holiday songs reverberate against my eardrums, and obnoxious clouds of synthetic fragrances waft, uninvited, into my sinuses.  Maybe I'm an idealist, or maybe I'm just a curmudgeon... but I don't understand how a season of giving meshes with a season of commercial overconsumption. If I thought hard about it, perhaps my aunt Ida really wouldn't be thrilled with the box of assorted oversalted meats, plastic vials of suspiciously labeled "seasonings", and cheap imported mugs with images of football playing reindeer.  But if the tacky mug set is the only piece of kitsch in an entire department store that fits in my budget, how much choice do I have? Lots, it turns out.  Handmade gifts have become increasingly popular in recent years, and it's easy to see why.  They're individualized and unique, they tend to use fewer resources and produce far less pollution since they're not made in a factory, they can be created with attention to detail and quality, and can cost little more than time and thought.  In this economy, most of us have limited funds.  Even if you're fabulously wealthy, a thoughtful handmade gift from you can mean more than a pricey basket that took no more though than whipping out a credit card. If you're browsing Instructables, you probably already enjoy learning about other people's ideas and sharing your own.  Whether you're a long term author or haven't yet posted your own Instructable, now is the perfect time to show us something you can make!  Have you reclaimed wool from a thrift store sweater to make a set of mittens for your mom?  Have you made a small batch of scented homemade play dough, or perhaps melted old bits of crayons into chunky, swirly new ones for a child in your life?  Are you brainstorming a plywood and acrylic laser cut clock for a loved one?  Whatever it is that you've made as a gift, we'd love to see it!  If you haven't yet... there's still time to get started.  This year, we have some fabulous incentives (as if you needed more reasons to make something for someone else).  Win yourself or a loved one a new computer, iPad or camera to document future Instructables! We'll be posting the Holiday Gifts Contest page soon, so be sure to keep an eye out.   In the meantime, be sure to check out the Reuse and Sew Warm contests already running.  There's still time to enter, and while you're there, be sure to vote for your favorites!

Squishy Silicone (shore hardness 30-10) with 4 ingredients

I owe my findings to the maker of "Oomoo" and community of hobbyists; thank you everybody! I needed squishy silicone, and the random knowledge I found here helped me with the puzzle pieces. The pink rectangle that you see in the pictures has the consistency of a gummy bear (shore hardness ~10). Grab: GE Silicone 1 caulk (or equivalent) Caulk Gun Odorless Mineral Spirits Baby Oil (Mineral oil) Acrylic Paint Sandwich zip baggies (medium large will help you) Cutting tool Mold negative (I use play doh because I only need basic shapes) Try to avoid glass... Don't use glass. A way to measure Tablespoons ADVISORY- your silicone (should) smell of vinegar and your mineral spirits will be potent of fumes.. and flammable. Use ventilation and protect your eyes. Your only saving grace is the baby oil scent. Okay. Grab the (new) silicone caulk and cut the whole pointy tip off of the tube, making a flush cylinder. Load that bad boy in the gun. Open a plastic baggie, and fill it with: 2 tbsp Mineral Spirits 1 tbsp Baby Oil (Mineral oil) Then shoot one full shot of silicone directly into the oily puddle of liquid. Close the baggie, leaving a little air. Find a way to mix it. I lay the bag on a smooth table and repeatedly iron the baggie with my pinky. You have 20+ minutes pot time, so be thorough. You should now have a clear 'spit' like liquid that runs, similar the two liquids you just mixed. Open the bag. Add: 1 drop acrylic/oil paint Close it, and repeat the mixing until your color is even throughout the liquid. Turn your baggie sideways and cut a small triangle from one of the bottom corners. Carefully tilt the bag like an icing baster and pour the silicone into your mold negative. This method is clean and offers control. You can squeeze ALL of your mix into the pour, as well as combat air bubbles. Don't touch it for 3 hours. Better yet, leave it for three days. It takes this long for the shrinkage to happen. You can avoid shrinkage if you use xylene instead of mineral spirits, but it is not available to me. The color will become opaque in this time as well. You now have very squishy silicone. I have tried many other pours and I can't manage to get the cured squishy consistency without mixing a liquid to start. A goop is preferable to me because I can use it a caulk, still, allowing me to 'draw' silicone positives. To achieve a shore hardness of ~30 Repeat the steps above, but now use: 1 tbsp Mineral Spirits 1 tbsp Baby Oil (mineral spirits) This will have an initially 'goopier' mix, and you will have similar pot/cure time, but no shrinkage. It will be oily until you repeatedly dry it. The picture of four silicone squares illustrates my last advice. Each mix has only one drop of the same pink acrylic paint. You may want to experiment with how much color you want. Far Left: the gummy bear mix 2:1 softest Inner Left: the hardness 30 mix 1:1 Inner Right: FAILURE did not cure (1/2 tbsp baby oil, 1tbsp mineral spirits) Far Right: FAILURE did not cure (2 tbsp baby oil, 1 tbsp mineral spirits) toughest The two squares on the right could have been made with just silicone, mineral spirits and NO baby oil. Maybe, add ~3 drops of glycerin and I could have had the same hardness AND a thurough cure, but I want the squishy. Hopefully this helps.

Pure cacsaicin from chilli peppers

I already had a quite long Ible in the making when it downed on me that not too many people should actually create such a dangerous substance at home.So instead I decided to just write a bit about the history, general procedures and what is possible or not.If you already made your own chilli exptract for a special hot sauce or your home made pepper spray then you feel right at home.Those who never done anything like it or at least some essential oil extractions might just find some other interesting stuff to read.I won't go into all details here as those with the basic knowledge will already know the precautions and most things.Capsaicin...The stuff that makes your exes run, clear you nose and makes you sweat like you on fire.At least if it comes within you favourite dish.In the pure form it is a severe irritant and should be handled like explosives or concentrated acids.You just won't make a mistake with this stuff twice - trust me!What really harms you is not the capsaicin itself, it is your bodies reaction to it!It stimulates the same nerves responsible to feel heat and pain, sometimes those for a severe itch as well.And unlike a normal reaction you would get from hot water, it won't stop until it is fully removed.Even after this the body keeps reacting for bit longer.On the skin you can end up with blisters like from a real burn, in your airways it can make breathing impossible!And lets just say that swimming goggles won't look as dumb and funny on your face once you realise you got some fine crystals on your face....If you dare to continue then I assume you are well aware of the risks, dangers and PPE requirements!Pure or extract?I checked tons of so called instructions on how to make pure or 99% pure capsaicin from chilli peppers.They all just produce a really crude mix of goo that happens to have a lot of capsaicin in it.If it is red or even darker it is nowhere near pure.If it has a weird smell that has really nothing in common with chilli than it is even worse.If it is more or less colorless, with a very strong scent that your nose does not like at all then we are getting somewhere.So why is it that we always end up with this color that is impossible to remove?Extracting chilli peppers....A thing most people ignore a bit when in a hurry is that an alcohol extraction requires DRY alcohol.You just won't tolerate water in it, which is why often methanol comes easier and cheaper than ethanol.Some people even think just because the alcohol is either evaporated or distilled off that all is good when using things like methylated spirit.Ever had the problem that you used that stuff and your hot sauce made you vomit after realising that it comes with a bad and extremely bitter after taste?That is the stuff that makes your home depot ethanol unuasable ;)If you use homegrown or otherwise fresh chilli you need to fully dry it first!Don't be fooled by people stating they did it with fresh peppers.What you get this way is some of the worst extractions you can get.Don't be fooled to think you need some Carolina Reaper either.A big bag of chilli powder from your grocery store will do just fine.So what is all in our extract?Alcohol or any other solvent usable for a capsaicin extraction also dissolves a lot of other things.Like the beta carotenes that give the extract the organge to red color.The skin and the entire fruit also contains oils, plus the shiny outside is mostly due to wax...All of this ends in your extract....You not only get what you want and might not mind but also everything else you don't want.Making the difference....The impossible we do right away, for miricles or wonder allow a day or two of processing ;)Assuming you end with a rather large qauntity of alcohol the concentration of everything is relatively low.If you used something like a Soxhlet extraction you already degraded a lot of the capsaicin due to the heat.And even after the best filtering you might have a clear solution but whatever is not a solid is still in there.Imagine you would put it all into a freezer....Surprisingly a lot of stuff won't stay in solution once cooled down enough.Especially if you give it a few days.Depending on what you started with you either get a slimy looking sludge or some crystals showing.Either way it needs to be filtered out and washed.For the washing use the same pure alcohol as before but make sure it is well cooled.If any cacsaicin was already forming crystals then they will be washed into your solution again now to a little extend.But you removed an awful lot of the wax if it was not capsaicin already. ;)Testing the slurry we collected.When using chilli powder from the shops I noticed that there is often no wax to be found at all.While for fresh produce the content is significant.Once dry you make a simple test with water.Capsaicin basically does not dissolve in water, so it would sink to the bottom while wax floats ;)I assume you ended with little to no wax but fine capsaicin instead.From the natural form it is very hard to get crystals bigger than a dust particle.This only happens if the temperature is cold enough and the concentration high enough.As my entire setup is quite small I usually prepare several 500ml plastic bottles that I fill to one quarter by height with chilli powder and then fill up to half with methanol.In the end I use a full 1kg bad of chilli powder but only a may of 5 to ten bottles.Making the most of it.When using alcohol extraction you want to use a little of the solvent as possible.Use means here wasting it instead of recycling it.Once I filtered my white slurry out I destill the remaining solution to reduce it by 50-75%.An almost dark red color is usually when it is time to stop.After this I place it back in the freezer for a day to check if more crystals or slurry forms.If so then I filter it off again.What is left is then mixed with recycled and fresh methanol to soak more chilli powder in my bottles.Means I discard the filtered of chilli poweder once washed, recycle what I can from the methanol and keep whatever the slurry produces that is not wax or dissolves in water.Depending with how much chilli you start you will get to the point where your filtered solution is already dark red.Since the final capsaicin won't dissolve in water you can destill with some added (destilled) water.This way you recover the alcohol without risking to get a sticky goo everyhwere that you need to clean off.It is quite possible to get some more capsaicin this way as with the alcohol leaving it will participate out.Simply filter the solution once the alcohol is recovered.As the beta carotenes won't dissolve well in water either it is best to perfom this destillation while all is mixed.If you can't do this then don't worry to much, it just means a few more minutes of cleaning later ;)Testing the final product....What you have left once the slurry is dried should be almost colorless with maybe a pale yellow in it.Fully dried it should appear as basically white.There should be no smell to it, nothing to tickkle you nose.Colorless and odorless.For whatever reason I still sometimes end up with a very faint smell.Not really chilli though...Depending on the temperature the products is either quite hard to almost britlle (when frozen) to almost wax like at room temp and above.I highly recommend against testing whatever you have on your skin or to ingest it!!!Waste some sauce base like ketchup (you can add it later to your sauce again) or some butter - I prefer the later.Butter become liquid well below the 65°C celsius decomposition temp for capsaicin, so it should dissolve very easy in it.Take a shot glass with just enough butter for a sandwich and dip a toothpick into your product.Make sure there it a tiny bit on it and not that the toothpick has a thick coating!Once cooled down while mixing every now then spread it on some sandwich and take a bite.After a minute or two you should definitately feel a difference to just butter - hopefully not too hot.If nothing happens repeat with a bit more on the toothpick.Still nothing at all usually means you filtered out only by-products and for some reasons managed to make the capsaicin disappear.Hints and tips that might safe your bacon....Methanol boils at about 64°C, ethanol at about 77°C.Capsaicin starts to decompose at 65°C.Not a big deal but if you get to the 80° mark, which is easy which ethanol you might have to use evaporation instead of destillation and waste the alcohol to your surrounding air...Water...For the final product it is not a problem but during the extraction process it is.Despite some people claiming otherwise both the quality and amount of what you end up with are lower.It seems some of the capsaicin binds to the water molecules with the help of some other stuff that the plant material provides.And when you try to destill a solution that was contaminated with water from the chilli it tends to foam up quite badly.While with pure alcohol and fully dried product there is no foaming.What to expect when collecting the end product...At room temperature you can dissolve what you get in product from one kg of dried chilli powder in under 10ml of pure alcohol.However at -20°C next to nothing dissolves in the alcohol.That means as long as you have still over lets say 1000ml alcohol extract then very little will participate out.Just one reason why I prefer to work with small batches - keeps the concentration higher from the start.The more you destill off and re-use the higher the capsaicin concentration in the alcohol will be.So before you start to add any water for the destillation you need to be aware of the consequences.I found out that first destilling most of the alcohol off the single rounds that got too dark in color helps.I just collect this conentrate for the final destillation process.Key is to destill this off to the point where it just starts to thicken up a bit.It should still be liquid but act almost like a thin oil.You don't want it so thick that is crates a coating on the walls when you move the liquid around.In case it did happen just add a tiny amount of alcohol again.Put in the freezer for a few days....Empty into your filter and let as much as possible drip out.Rinse with as little alcohol as possible - have the rinsing alcohol at -20C as well .Do not wash the filter with water but with the frozen cold rinsing alcohol.Cover the filter up and leave in a cool place for the next run - have something under it as it might still let a drip or two off.The remaining liquid leave to evaporate off until it just starts to thick up again a tiny bit - back in the freezer for a day or two.Filter out again then while still a bit wet turn the filter over to remove most what is in it.I prefer to empty onto a teflon sheet and to wear full PPE here....While still wet you try to remove more from the filter with a fine but short brush, knife or whatever you find suitable.Do not continue any action once the stuff starts to dry!Place the filter into a sealed bag and leave in your freezer for when you do anthoer extraction - this way you loose far less product ;)When doing a final destillation with added water to cover all the alcohol you are left with the remains of the original product, minus all solids.Beta carotene is quite beneficial, so it would make sense to include it into your hot sauce.Plus there will always be some leftover capsaicin in it.If you want to use this part of the extract as well to really get what is possible then IMHO slow is better.You can't just destill off or boil off the water to get a nice "sauce" base.The capsaicin that is left would be mostly decomposed and with no effect anymore.A clear sign of too much temperature is bad smell that really turns you off.Hard to define in words but trust me, if you smell it you know what I means as you woul refuse to have this smell coming from your final hotsauce.During the summer it no problem to just leave it out to evaporate in the shade !You can do it in full sun but must make sure no sunlight gets into the liquid.UV decomposes at least a lot of the karotenes....Special equippment at hand? If you happen to have a vacuum pump or at least a salvaged fridge compressor you can safe a lot of time.A buchner filter for 500ml in the top is quite cheap but you can build something similar with a normal funnel.Look it up it you want...A proper buchner filter however already comes with a very fine glass filter built in.Means you don't really need any filter paper - I still add it as it makes the cleaning easier.Instead of waiting several hours for gravity to do its work on a coffe filter you are done in a few minutes.Well worth trying out!For the water destillation of the remaining end product, or by-product if you like, vacuum also helps.CVD or Closed Vacuum Destillation sound complicated but is really simple.One pressure vessel is filled with the solution to be conectrated, the other is kept empty.Connected with a suitable pipe or hose and fully sealed.The extract is heated to about 40°C while the empty vessel is placed into an ice bath.With the pump and the help of a valve create just enough vacuum so create small bubbles in the heated vessel.Close the valve and a few hours later there should be far less water in the hot one while the frozen one builds up ice.Every now and then check the vacuum gauge and if require start the pump again.You can do with just the pump and one vessel....Problem is that the oil in your pump will quickly get far too contaminated with water.You could add a conatainer with something like an absorbent but it would have to be sufficient for all the water you need to remove.Most of all it must be able to absorb it fully before the airstream enters the compressor.The benefit is that the capsaicin can't decompose at all.In a vacuum or close to it anyways, a lot of the things that procude smell also disappear through the compressor.Won't help it was already a stinky mess but will certainly reduce the smell of the concentrate.If you prefer to keep this aroma for your final sauce then do not use a vacuum.Why not a Soxhlet or similar device as used for essential oil extraction?The benefit seems to be clear:You have a relatively large vessel to hold a lot of chille powder and can let the alcohol cycle and wash it out completly...Theory is not always reality.....Firstly the alcohol runs through it many times while it dissolves what it can from the powder.That means each round you actually wash with a higher concentration until there is equal amounts in the alcohol and the powder.You waste about 50% of the end product unless you repeat it all several times with fresh alcohol.Worst of all however is the temperature, even if you use methanol.To make the alcohol evaporate enough to make the process work properly and in a timely fashion it must be heated to above 65°C, in most cases even with a proper heating mantle you won't have the temperature control tight enough.It is quite possible to destroy 70% of the capsaicin this way....The condesers used are also not really suitable for these low temperatures.Means you should use ice water to cool.Either way you will loose a lot of what could otherwise be product.Funny things that might stumble you along the way.In the freezer the solution will participate out a bit.However, when back to room temperature most if it will still be there, only a fraction goes back into solution.I could not figure out why this happens but once heated to about 40°C it all dissolves again.Filter fully blocked by the product?The fine sludge can be a problem even with a proper vacuum filtration unit.Especially if the product is still not really a solid once fully dried.A paper filter can be re-used many times but whatever makes it past and into the glass filter is tricky.You should not get much here if the paper filter was fine enough but if it builds up to the point where it makes the filtration long and slow:Remove the paper filter and add a small amount of luke warm alcohol.If it does not start to trickle through already give it a minute or two before turning the vacuum on.Starts a bit slow but should clear up quickly, if in doub repaet with a large volume of alcohol.I prefer to do this cleaning before I start a new bag of powder or whever I need to restock.Means I can use the same alcohol I had to clean the filter to add to the bottles with powder ;)Nothing gets wasted if you are prepared....If you find any typos in the above then feel free to keep them.However if you decide to use the typos for monetary gain I would kindly ask for 5% of the net profit made from my typos.;)
