Does anyone know the toxicity of chromium, or more specifically the toxicity of burning something chrome plated?

I know I'm probably going to sound like an idiot for asking, but can magnet wire release any toxic fumes when heated? I made a speaker using a magnet-wire coil and a neo-magnet, and when I plug it into the amp, I realized the coil gets very hot. I was expecting this, for I've used a number of coils in other projects. There is an odor, no doubt, that comes from every coil I've used when making an electromagnet. Sure, the smell may come from the iron nail being heated, but I always associate the smell with the coil. I'm not willing to smell this speaker, however. So, is there any risks that come from the heating of magnet wire? The coil gets hot after about a minute of run-time, but I'd like to be able to run through an entire album of music (an hour?) if possible. Thanks!

I have made a tabacco pipe out of a brass bowl and a copper pipe that fits into the bowl. i have heard that copper gives off toxic fumes. will it do so if it is burning in the brass?

I was wondering where to find those multipurpose metal barrels like the ones you find conveniently scattered across landscapes in first person shooters.  They also seem notorious for holding toxic waste in movies.  I was thinking it would be at some kind of surplus store. Can anyone help?

Does anyone know the toxicity level of various styles of playdough? (Store bought or homemade). When I was a kid my mom had a recipe with flour, water, salt, and something else, and we never really ate it cause it tasted terrible!Just wondering what is the safest for our little one to play with. Thanks all!

My spouse washed a bunch of antique children’s china in the dishwasher. They were from a garage sale and he didn’t realize some had been glued back together. The glue must have broken down and melted during the wash. Now the dishwasher smells awful (like chemicals) along with everything that was washed in it. Do we need to replace it?

While the color green has been the hue of choice for environmentalists and companies wishing to show that they care about nature, making a product green is actually toxic. Due to the difficulty of making a green dye and all the chemicals that are used, it contaminates anything it touches. So when a product is simply putting some green to make it look a little more nature-friendly, it's actually making things worse. Yay! From the NY Times: Take Pigment Green 7, the commonest shade of green used in plastics and paper. It is an organic pigment but contains chlorine, some forms of which can cause cancer and birth defects. Another popular shade, Pigment Green 36, includes potentially hazardous bromide atoms as well as chlorine; while inorganic Pigment Green 50 is a noxious cocktail of cobalt, titanium, nickel and zinc oxide. The Toxic Side of Being, Literally, Green

I dont know what type of bamboo it is but just in case how would i make it so its not toxic?

I don't know about the rest of Instructables community, but I am extremely reluctant to contribute anything to Pepsi's latest (https://www.instructables.com/contest/pepsirefreshproject/)  greenwash campaign, well, anything except criticism. PepsiCo (PEP) is a company that produces semi-addictive, food-like consumables that, in the aggregate, are actually harming people's health. They're also littering the world with PET plastic bottles. Previous Instructables alliances with companies that make tools or building supplies (Black and Decker, Leatherman, Gorilla Glue), these alliances made sense to me since these companies actually make products to help people to build things. PepsiCo is essentially a manufacturer of recreational over-the-counter drugs, similar to beer, liquor, cigarettes.  Thus alliances with entertainment industry (e.g. ball games, car racing, crappy pop musicians) would make sense to me, but not an alliance with Instructables.com, whom I like to think is doing something more noble than just crass, brain-numbing entertainment. If you'd like to see PepsiCo's official explanation of this "Refresh the World" business, but without being tracked by DoubleClick, the direct link is: http://www.refresheverything.com/how-it-works Pepsi says they want to change the world, but I think they just want to sell more soft drinks.  I don't see them as a serious agent for change in the world.  IMHO, the revolution will NOT go better with Pepsi! Update:  Many of people responding to this topic seem to think that I'm lobbying for the prohibition of soft drinks, but this is not my goal. In truth I wish more recreational drugs would be allowed to have the same legal "white market" status that sweetened drinks and snack foods enjoy. The point I was trying to make is that Pepsi is an inappropriate choice for an Instructables alliance because the basic values of the two companies are so different. Pepsi does not embody the DIY (do it yourself) philosophy. Rather the values of PepsiCo are convenience and instant gratification. This is essentially a SEDIFY philosophy (somebody else do it for you), the polar opposite of DIY. The reason I mentioned harm to the heath of people and the planet, is just to demonstrate that Pepsi does have cause to want to improve, or greenwash, their image, which is I suspect the point of their "refresh project", not just pure philanthropy.

I've made a hot wire foam cutter but I'm wondering now if the fumes are cancerous/dangerous/toxic when you breathe them in. I've researched this myself a little but there are mixed answers and many others are unsure. Any answers?

I ordered glitter halters for my horses but the glitter falls off. Is there a safe product I can use on the halters to keep the glitter on without any danger to my horses either toxic smell or indigestion? 

Are there toxic vapours produced from using ferric chloride to etch pcb boards?  I want to present this process in a classroom but there are no windows and wondered if this would be hazardous. There's also the method of mixing hydrochloric acid and hydrogen peroxide to act as an etchant. Thanks!

I was going to make an instructable on mini roasting when something hit me. When you use the lighter to light maybe a marshmellow, is the fire or smoke or fumes from the fire toxic? I mean the gas/alcohol gets neutrilized when it burns up and turns into flame but If i cook with it, it may be a different question. If someone asks me to think about smokes, the I should say to you that smokes are already toxic and anyone smoking shouldn't care. ( I don't smoke, I want to live) If possible you can answer this question and have credit in my next instructable.

How much cloves is too much? I see on the MSDS that the rat LD50 is 1930 mg/kg, which no reasonable person would consume in one day. But I wonder about the effects of consuming a large amount every day. Can anyone find some data on the lowest reported oral dose of eugenol (in mg per kg) that showed long-term toxicity in a human? Or, conversely, the highest reported dose that was shown to be nontoxic over the long-term?

Preferably non-toxic and inert, to make the silicone caulk/gel more viscous, to allow it to flow into a mould more readily.

How can I test plated or unplated metal components for lead content? The components I have are all kinds of metal washers, nuts, gears, wires, etc. I know there are at-home lead testers available, but they are not really made for testing metal components. I have over 50 different samples to test, so the $4 swabs are too expensive.    

Right at the end of our daily meeting this foul stench began to swirl around us. We couldn't quite figure out what or where it was coming from, but it was nasty. At first we checked the laser cutter since some people in the building like to occasionally burn Stuff That Shouldn't Be Burned and oh man does it reek. But that wasn't it. We check the fridge, but it was fine. We even discovered that it was just inside the building, but we had no luck figuring it out. Then Mike from Potenco walked down the hall and said, "Oh, hey, sorry about the smell. I blew up the transformer." He grinned and walked off to find all the fans in the building to air the place out. Just another day at the tower and another experiment gone awry. But if you don't blow anything up, then you're not going to make any real progress, right?

Hi gang, I know CA glue (Krazy glue, Cyanoacrylate) is solvent based, and inhaling the solvent is bad for you, but how safe is it after the glue cures? As I understand it, after curing the glue is basically a plastic.  Can I use it in a baby's crib (Assuming it's allowed to cure)? Thanks!

I've been wanting to make a small mallet out of a tree branch, And I recently spotted a small olive tree branch that fell. Since I'm pretty new to woodworking, I thought I'd google the wood to find out it's properties, This is the confusing thing that I found: Here, It says that Olive Wood is commonly used for "kitchen utensils, carved wooden bowls, cutting boards, fine furniture, and decorative items", Which means that it should barely be something allergenic, Aka safe to use, Since it's used with food. But here, It says that Olive Wood is "Olive trees are extremely allergenic, with an OPALS allergy scale rating of 10 out of 10" aka "9-10 Extremely high potential to cause allergies, should be replaced with less allergenic species". Now I'm confused... Does anyone know what really is true?

I have some old furniture, etc, that I would like to repaint, but it's al covered with old nasty enamel-does someone have a suggestion re covering/sealing the pieces so I can use water-based paints to redo them? I know about sanding first, just don't know if a non-toxic version of the right sealer exists or could be 'created.'

My mood ring broke and I got some of the stuff on my hands is it toxic?What should I do.

Is it worth it to take the electron gun out of a CRT when salvaging parts? I've seen people remove the electron gun when they take apart the CRT but I don't know what they'd use it for. What can you do with a CRT electron gun? What chemicals does the gun contain? (I know the screen has toxic phosphor and stuff but I'm talking about the gun itself). Also, is it safe to vent a CRT tube? I have found that you should vent the CRT tube before working on it, by smashing the end from a distance, so that it won't implode if you happen to break it when working on it. But is it safe to puncture open the tube? There are toxic phosphors inside and I worry that venting it could cause toxic chemicals to go airborne.

I've been looking around and it seems like most catalytic converters have palladium in them. I think palladium is mostly inert but palladium salts are highly toxic. I would like to open up a catalytic converter and use the substrate to make a thermoacoustic engine stack. So do you know if it would be poisonous to me to open a catalytic converter? Thanks!

My chinchilla is, for the most part, a jerk. She is adorable, though, so I'll keep her. I can keep up with all of the ways she tries to antagonize me (I've come to the realization that she really is out to get me :P ), except for one. She often pushes her food bowl off of the ledge. I would move it to a lower area in her cage, but, as I came to realize the first time, she poops into the bowl when it's below her. So, I must keep it on this ledge. I therefore need a way to attach and un-attach the bowl to the cage (so I can fill it with food afterwords). I could just go and buy one of these food-bowls,  but I'm too cheap and like to make my own stuff, anyways. So I have two questions - what material would be best for attaching it to the cage, and would hot glue work as an adhesive? I am worried about her gnawing on the stuff, because I know certain things can kill her if she eats them (eg: Paint). Thanks! :)

I·d like to found how to make photo-sensitizer out of chlorophyl extract, or from micro-weeds, or other any organic like plancton, to replace the very toxic technics used in every photo-reproduction work

I have decided to make a set of wooden blocks for my son.  I'm using Mod-Podge to decoupage pictures and designs, along with acrylic paint on the blocks. I know that Mod-Podge is water soluble, so it could make for a pretty gummy block after a 6 month old attacks it.  I'll need to make it water proof somehow.  On reading a particular Instructable on these blocks, the author said to use a non-toxic acrylic sealer.  I could not find such a sealer (or none stated "non-toxic") at the craft-store.  What is a safe brand or alternative to use?  OR. . . Mod-Podge aside,  what kind of method would YOU use to make these said set of baby-safe blocks? I thank you, kindly!

I was biting it as I always do(very attractive) and it broke it my mouth. The plastic covering came off and I consumed the inside on accident. Will I be okay? I know it doesn't matter if it touchs skin but this is diffrent because I swallowed it. HELP ME

I ate some... but... AM I OK???

I heard something about LED light bulbs containing lead or arsenic. Does this apply to LEDs like the small kind?

I would like to sell food smoked food that's been smoked with wine barrel wood. Ive been told that all barrels are treated with linseed oil or flax seed oil on the outside of the barrel and that burning this is toxic. Cant find any info and need some secure info so I don't get sued! Chow, Lance

Hello, I'm working on a project and I really need to make a glue for gluing powdered seashells (CaCo3 basically), this glue has to be non-toxic, waterproof and moldable. Please help me!!!!!!

Does anyone know where I could get some non-toxic food safe epoxy/glue? I need it for a project that deals with sealing things that comes in contact with food. Any replies are much appreciated! ,Thanks

I want to fix a glass but i dont know if i can still use it. yes, i know i can buy another one but lets just say its a cup i need to fix.

My freind has a large supply of microscopic gold particles, however they need to be separated from sulphides. there is a high concentration of gold in this solution, and millions of dollars could be made. however, heating the sulphides will make sulpheric acid, which burns away your lungs (also used in chemical warfare). chemicals currently used for the process of separating sulphides from gold are very toxic, and also expensive. the chemical process is very inefficient too. i am looking for a way to separate sulphides from gold without using (toxic, dangerous, expensive, rare) chemicals.

What should I use to seal two glass plates which will make up the sides of a shallow tank of a solar water heater? It should be able to resist temperatures of up to 80 degrees Celsuis.

I have used alcholal already, but I am looking for something more efficient. It will need a high flame (e.x. wood won't work).

Does anyone know how toxic the foam inside a refrigerator door is (Urethan foam?)? Is there any danger in coming into contact with it? All I can seem to find online is long-term effect of the foam on the environment (which are apparently very bad). In short, should I cover up the back of the door and never think about again, or can I remove it from the door with a chisel without much worry? I want to remove the foam because it looks a little moldy on the top. Any suggestions? I'm making a magnetic bulletin board for my wall in case you were wondering. thanks, Randy

I'm a quality engineer working for a company in Turkey, the company collects the coaldust ( powder form of the coal )  from all the cities of Turkey and makes them briquettes by pressing with very powerful machines. Of course we use some adhesives for mechanical strength of the briquettes. We use CMC (a kind of cellulose) and this material is soluable in water. So our briquettes are not very durable under rain or moisture. Now I have to change the binder or adhesive materials in order to produce waterproof briquettes. I dont know how it's possible. I have to use nontoxic natural materials, and cheap as well. Last week I tried to do something but we were unlucky maybe. I tried to use Technical Gelatin and Alum (Al. Sulphate ) together, the briquettes seemed very good after production but they were not durable when I left them in a cup of water. So I have to find a solution now. Can you help me about that? I'd be very pleased. Thanks.

I was told that its toxic to smoke food with wine barrel wood because its treated with linseed oil to make them waterproof and to keep contamination from going thru the wood. Ive searched all over the internet but cant find any info on the health effects of the smoke. I see many people selling this wood and I have tried it for smoking food but don't want to sell something that's harmful to eat. Any for sure info as it could be a legal problem for me. Chow. Lance

In this video http://www.youtube.com/watch?v=_Filk4I4Axg&feature=related  this guy makes a still from a stock pot but he used some toxic sealnt to make the pot air tight what can u use to seal the pot and still be able to open it when i need to add more mash to it thats not toxic??

Hi all,  I really need your help. My son has a dress up party and is determined to stick this prop to his body. It is not heavy but I need an adhesive to stick it to him that ideally would be water soluble and not irritate his skin.  Is there anything anyone can think of? Thank you so much Eliza 

I have a country voice, but I am in a metal band.

Inexpensive, non-toxic, fun, educational. Thank you.

I can do a death growl for quite a long time, but I have never been able to scream.

Everytime I click on comment it takes me back to log in,,,I've logged in 10X already!

Does anyone know know a way to rid my garden (and porch) of aphids/ spider-mites ...kid friendly- non-toxic please. thank you

PVC  is one of the most toxic products ever created - seems no-one here realizes this - PVC is NOT something to play around with - esp not for indoors! Google it!

I want to paint my bill miller bbq mug and decorate it and still be able to use it daily for drinking my tea. Is there a safe non-toxic method?

I was wondering if it was possible to have specific power options for programs such as anti virus or media player. I'm using a windows 7 Home Premium. Both software is by microsoft incase that matters. I wish to have the computer recognize those programs and let the computer still run while the lid is closed. I don't want  to waste power with the screen on uselessly, and screensavers aren't suitable for me because i do browse youtube quite often and they start to bug me.
