I'd like to build a kiln with an interior roughly 8 cubic feet (2' x 2' x 2'). Does anyone have any experience making such a device or have any suggestions on how to do it? If it is only practical to build a smaller one, that's perfectly fine as well. Thanks

I do not have access to a kiln nor do i have the money to buy one. Are there other ways to harden the clay that will make it as hard or nearly as hard as a kiln would? I thought air drying would make it resonably hard, but nope it shatters WAY TOO easily. EDIT: I should have noted that I live in the heart of LA in an apartment so I can't really make a kiln, but it seeming like i need to kiln it or buy some oven clay(I forogt the name)

I'm working on some fused glass projects for sale, and I'm trying to figure my kiln's electrical consumption into the price of the items as accurately as possible. I can easily figure the max draw of the kiln, but it's not running full tilt throughout the whole fusing cycle. In fact, through much of the cooldown phases, it hardly comes on at all. I don't want to grossly overestimate and gouge the customers, but I also dont want to underestimate and lose money on the sales. I also don't want to buy a 220v wattmeter that I'll never use again. I don't need super-precise measurements, just reasonably accurate ones. Is there a feasible alternative to a wattmeter for this application?

I have a question about the Clay contest criteria....debating whether to do an instructable for a DIY downdraft kiln vent for under $50 (cf $450-600 to buy) that I built. I've actually been waiting for the clay contest before publishing, however the contest criteria says: "For the purpose of this contest, any project that uses a moldable, malleable, clay-like product will be eligible." So question is, would a kiln vent be eligible? Previous contest criteria has been "all things" related to said topic, but this seems more narrow in scope. Obviously a kiln vent is not made with clay, but it certainly fits the pottery topic. What to the contest gurus say?

I have a kiln that I need maintained at a certain temperature for an extended period of time (9 hours). Problem is the kiln I got doesn't maintain its temp, it just constantly supplies heat until it would kill itself. Making me sit there for 9 hours turning it on and off exactly once a min. Obviously this is a problem... there is a physical on and off switch where maybe I can rig up some timer to hit it for me? Otherwise maybe there is a way to modify the wall outlet to supply power 1 min on, 1 min off? Any suggestions would help, thanks :D http://www.clay-king.com/images/quickfriec.jpg

Please help! I need room to work in. I live in a very crowded double wide with 4 kids and a spouse. I need space to myself and my artwork before I go mad or am forced to quit my beloved arts. I paint, make jewelry - both metal and pottery- this means fire and small kilns. I have a back porch and it is very small with an roof over half of it. I have almost 0 money. How can I have a workspace? With the kilns I can work thru winter (in the south- sorry to be a stereotype). I was thinking hoop house with one side being the roof of my house. Perhaps extending the porch, with donated or used lumber- to give me more space- but the enclosure is an issue. I need light and I need to be closed off from bugs. I can lay in a window cooling unit and a space heater. Please- Ya'll are geniuses! Please tell me how I can do this. I will go mad if I cannot have my art and my space! S

I am making some highly detailed prototypes, and Im using polymer clay for the details. I've been baking them in my kitchen oven, but it's starting to get hot with summer coming on... I want to limit the heat production in my house! I have an old toaster oven, but it's too small for my items. I was thinking of taking it apart, and using the heating elements and temp controls in something a little bit larger. I'm wondering what the community thinks about that? My temperature needs to be 275° for fifteen minutes at a time. Some temp fluctuation is okay. I'm thinking 14 inches cubed would be plenty of room for my largest pieces. somewhere I noticed someone using cement board as an insulating wall, I was thinking a cube made of that with a hinged side.

Question by kkf | last reply
I have a workshop which has 2 x 1000w kilns. To fire my pottery etc, I need to put a kiln on for about 12 hours. No ordinary cheapo timer can handle the wattage load and so I am thinking of using a heavy-duty relay. Are you good with relays? If so, I would value your help, please. What I want to do is plug my timer into the mains socket, have the relay connected to the timer so that it knows when to switch on and off, and then I need two outlets (one for each kiln) so that when one is switched on, the other is off, and so on. I have thought of a 30A, 240v relay which is SPDT. I have deliberately over-specified the relay because I want it to be safe and to last, as well as use the thing for other applications where there may be a large inductive load (as opposed to resistive load). I can provide a link to the relay, but I'm not sure if this allowed. Many thanks. Kevin

I was thinking of this theoretical circuit making system. I would get some sort of powdered or granular metal (possibly lead) and mix it with small amounts of water. Then I would fill the paste in an ink jet printer. Then I think it's as simple as just printing out the circuit. Maybe you would have to bake the print or maybe put it in a kiln to let the metal melt together.

Has anyone ever used copper tape to concentrate heat on an object to obtain a uniform higher temperature? I've been doing some studies in the recent past that suggest polished copper foil is a good reflector of infrared energy. It is not as good as silver, but I don't think it would go over well to use silver in any sort of oven or kiln. I used to think good ole aluminum foil was good for heat, but it turns out it is only good for stopping heat. I've thought of using the instructable on the waffle iron or make one by way of a bread toaster, but will most likely not be able to go through with it. The copper foil is the same type found at stained glass craft shops.

Does anybody have any tips or techniques for breaking out of a spell of artist's block? I've been somewhat uninspired for a couple of months now, and it's making me crazy. I'm dying to create something, but every time I go out to the studio, I just wind up staring at the tools & materials for an hour or so, getting frustrated and leaving. I've tried just starting to work in the hopes that the materials would tell me where they wanted to go, but the results have been less than satisfying. If it's helpful, my current areas of interest are kiln glass (with an emphasis on recycling old bottle & window glass) and copper enameling. What have others done to get out of a creative slump? Any and all help is greatly appreciated.

Hello Everyone, I'm new to this forum and I have made something I wanted to share and get some feedback. This is "Art Knife" I used a method I invented to etch hardened glass with colored images and made some into what I think is a pretty cool knife. The glass is held in place on a nice Damascus blade with a Sterling Silver frame. The etching can be of any subject, I chose the animals because they look nice but I could have put a portrait or other designs on my knife. I also want to use this technique for other fine items like memorials, awards, etc. The etching never wears because it's covered in a layer of Pyrex glass by baking it in a kiln. What do you think of this idea? Any feedback greatly appreciated! Cheers, John

I'm looking into making myself a Go set. It's a very old Asian board game. There are a couple instructables on making a board itself, which is pretty straightforward. My problem is in the manufacture of the stones. Basically the stones are flattened out marbles in either black or white. The idea is a bi-convex round stone, usually between 5 and 9.2mm thick, around the size of an average thumbnail. Traditionally these are made out of agate, slate or something similar. My goal is to produce stones that are hard and rather heavy, to mimic the actual stone feel as much as possible. I'm going to need 361 stones for a set, and I want to make several sets (maybe half a dozen). My current best bet is to press clay stones with a mold, fire them without a glaze to avoid non-uniform surface due to contact points, then spray an acrylic coat for color and texture. I was hoping someone might have other suggestions. I was considering an epoxy/resin option that I could press in a mold, then dry into a hardened, dense synthetic stone. But I know very little about epoxies and my options in this. I've considered glass and machined metal, but I lack the facilities and skills. Stone is beautiful but I don't know where to start with detail grinding and mass production at the same time. Wood would be great, but I would have to find/make the world's smallest lathe and I think the man hours needed would be impractical due to the quantities. I'm limited in tools, resources and knowledge on the subjects at hand. I like the idea of making a mold with which I could press several stones at once. Cheap is good and the ability to do this without a kiln would be great. The clay seems my best option but my kiln access is limited, so firing upwards of a thousand stones would be difficult. So if you have experience with a synthetic that I could pour and harden, I would greatly appreciate it.

What does a municipality do with old traffic lights? Why, they can make them into dinner plates! Recycled Glassworks makes plates from old traffic light covers from retired lights, often the ones replaced with the newfangled LED kind. Oddly, the green lights end up as blue plates... dunno if this is an artifact of the plate-making process or if the light behind is very yellow, necessitating a blue "green" light.But while that's probably their most dramatic product, there's another. Most glass recycling is limited to bottles and jars. The only thing to do with broken windows, or broken glass tabletops, or other glass of this kind, has been to throw it away. Recycled Glassworks accepts this kind of glass in addition to the traffic light kind. They cut it to size and kiln-bake it in a mold (a process called slumping) to produce extremely attractive bowls and plates.Way to go, Recycled Glassworks!

In my enameling work, I sometimes use a mild homemade pickling solution to remove firescale (cupric oxide) from copper. The pickle is a saturated solution of white vinegar and kosher salt, kept hot in a Crock Pot. After heating the copper pieces in a kiln, a layer of cupric oxide forms on the surface, which is then dissolved in the salt/vinegar solution. After a while, the solution turns a lovely blue color from the dissolved copper. If I forget to put the lid on the pot, eventually the solution evaporates, leaving pretty blue crystals that look a bit like copper sulfate. So, what have I got here? I don't want to just dump it due to the copper content. I'd like to figure out something to do with it, but first I need to know what it is. I'm thinking it might make a good electroplating solution, but that's just a guess.

I have followed the evolution of the 3D printer and I can see its potential as a real tool for home use. Ceramic krafts have been a fairly easy home size cottage kraft for centuries. Now If you had a small kiln and you were able to model Items from house wares to mechanical parts to ceramic molds (ie Cookie or decrotive bread pans or a Ceramic motor block to an Air Motor). I thought if you Cure/ dry it (ceramic paste) as it was extruded on to the model with focused lasers (ready for deburing and then a bisque firing) as in using lasers for curing/ hardening of a polymer mediums. The variety of Ceramic Mediums/ materials that could be used to fuel a boon to the unemployed as a way to make money. Maybe printing out one use molds, to form cores to Graphite products that could be washed out after and have the mold material reused. If there was away for me to follow through with the possibilities. Extruding those oven cured clays, that could stretch its usefullness. I am trying to figure out a way to get out from under the pile and recycle as much as possible and use as many American made parts and electronics as I can. Graphite fiber empreganted ceramic material, is there such a product out there that could be utilized in 3D printed parts? Is there a Market for Products made of these types of materials? So many questions, so many possibilities.

Now before you rush to write down an answer let me tell you the details! The chunk of glass is 28 inches wide by 28 inches long and 2.5 inches tall. Composed of 160 painstakingly cut strips of glass that have been glued together into a jumbo block. Now try as I might, when laminating things together of ever so slightly different size together you are going to get high and low spots - And yes, this would have been soooo much easier a job if I had smoothed out the rough edges before laminating - Pesky hind-sight. Unfortunately my planer doesn't seem to work so well on glass, who knew :) Anyway, I will post some pictures to give you an idea of what it is, that has to be ground down. First off • It does not have to be perfectly smooth • A mottled surface would actually be appreciated • It is not going to be a lens of any kind, all though light will be transmitted through it. I have the following tools, but first - No I am not taking it 1700km to have it kilned. No, the local glass shop seems to have less tools then I do, at least in this scale. • Angle grinders • belt sanders • orbital sanders - but really? On the back side I used the angle grinder, with a metal grinding bit. Not to bad really all though the edges were taking a pounding. This was prior to applying resin and woven cloth, to give the glass a bit of tooth and reduce the high edges. This is for an instructable I am working on.

I have spent a great deal of time working on this question yet, I have no solid answer to go on. I tend to enjoy acquiring a skill set which would be very useful come TEOTWAWKI (the end of the world as we know it). I am far from a prepper, however I still entertain a slight possibility and see no problem with learning how to do a little more than cope. These skills extend from knowing where to grow, gather, and how to store penicillin to simple things like a yeast starter 100% from scratch. Brewing and distilling are also handy because it makes a great trade item. These are all things you never see in the Walking Dead or any other TEOTWAWKI cinema. One of the more important skills I believe would be conjuring fortress walls from rocks in the form of a little thing we know as concrete which we all take for granted. Now I could mix portland cement and filler with some water all day long and make a pretty cool fortess, but seriously. All the home depots in my state wouldn't have enough quick rite for that. So today I wan't to know what general rocks and minerals (that you can find in nature) can you combine to make cement. I know there are all kinds of fancy names for these, but what I really need is some good old generalities. Tell me to go outside grab a handful of clayish dirt, but it in a kiln with some lime and grind it up. I'm not looking for top of the line stuff here, this just needs to be able to hold a general form for a few years and be a little bullet resistant. This is for a crude fort, not the tallest building in the world or the hoover dam. A simple mortar would also be nice, although there really aren't any stones around to put together, bricks aren't super hard to make with as much clay as we have in our soil. So join me and maybe I will put together an instructible on all the skills you actually need but don't have!

I am searching for inexpensive means to create aesthetically pleasing electric stringed instruments. I started this project when I started playing viola years after I was forced to quit private lessons. I discovered the F-f-fiddle on openfab.com which is a super rad 3d printed electric violin but since I do not have access to any 3D printer in the tiny town which I reside in, I sent the files to an online 3D printing business and they quoted me at least $500 just for the Fffiddle body! I didn't even bother to ask for a quote on the electric ukelele which I want to print & build so badly as well. I am interested in this project so that I can possibly help low income public school students in creating their own instruments to inspire them to take up an instrument and show them how much fun it can be to create something by yourself rather than buy. I am especially interested in acrylic plastic/lucite/celluloid, resins, exotic wood, recycled plastics, plastic injection molding, piezo pickups, and any other interesting materials that could be incorporated into these projects. I have been studying luthier tools, supplies, etc, along with design/fabrication of lucite/acrylic stringed instruments, furniture and other home goods. 3D printing/scanning, vintage celluloid guitar finishes, pre amps, recycling plastic bottles, landfill harmonic instruments, leather, pearl inlay, metallic finishes, enameling kilns, metal smithing, hand engraving & everything in between. I have been a mixed media artist for nearly my entire life and my father was a jeweler. I am going to find a way to create some functional and beautiful instruments no matter how long it takes me to narrow down the right combination of materials and how to make them, model them, mold them, dye them, etc! The photos attached are simply inspirational photos which I have collected over the past 6-8 months. Many of them are possibly patented, licensed, etc and I do NOT want to simply RIP OFF any of these photos! Please email me at email@example.com if you believe you could help me with my low income student instruments program or leads on 3d printing grants for public schools or anything else that may help me on my latest project or contact me directly via my instructables question here. I especially am interested in creating an electric violin which incorporates both classical and contemporary design. Any advice? Could you help?
