DIY Polygonal Top-Loading Electric Kiln
(Click Image to Enlarge)Check out this detailed building of a 5.6 c.f. 37.5 amp polygonal top-loading electric kiln:
“This set of pages diarizes the construction of my kiln. I fire to cone 6 oxydation and use an electric kiln to do so. The kiln I’ve used till now is a very old cone 1 Olympic, it is also very small, around 3 cubic feet. It definitely needs to be replaced, for efficiency reasons. It can barely reach cone 6.
Hobby type electric kilns like this are not complicated pieces of equipment. There seems to be a pervasive attitude that you should not build electric kilns. People believe one should buy electric, and build fuel. I don’t think this makes a lot of sense. (Though in an institutional setting you may prefer buying simply for liability reasons.) There are three good reasons to build your own kiln, cost, quality and knowledge. The third reason motivates, I want to have confidence in knowing how it works to help me in repairs. Cost and quality are kind of the same reason, you can build a much better kiln for half the cost than you can buy. Why shouldn’t you build one? The only good reason I can think of is liability.”
