Casting burn-out | burn-out kiln Hello. I wonder if anyone has a good burn-out kiln for sale, or knows where to find one. I am searching for a small economical burn-out kiln to melt wax out of ceramic shell molds. I'd like something that will fit several (three to five) 2.5-3 foot tall shells at once, something that has a provision for collecting wax and has an after burner, and something that runs on propane (preferably). I'd like to avoid having to build one, so that I don't have to spend too much time away from sculpting. Thanks!!  dewaxing kiln for ceramic shells

I have been casting for over 20 years and I dewax each shell suspended on a high temp wire over a tub of water and let the wax fall into the water. I allows me to apply more heat to some areas while not heating other areas or heating the entire thing at once. Does not burn the wax too much, just at the end of each shell. I have had to buy very little wax over the years besides the wax I first started with. I use nichrome wire for the hanging wire. Seems pretty fast, a kiln process might be a bit faster but I do not have to have another kiln to do the dewaxing this way. If I wanted to make a burn out kiln, I would use the same ceramic blanket system I use for making my shell kiln and my melting furnace. You can see what these look like on my website in the foundry section under making equipment (http://mlce.net/www.mlce.net/Pouring_Metal.html). The picture is in the lower right corner. If you have any questions about building these kilns, please feel free to contact me vie the net or phone (360-681-4240). I live in the far north west (west of Seattle, WA). Happy to help if I can.

You might look for a used small electric ceramic kiln. I use a small L&L kiln that is programmable. It is very reliable. Good luck.
