Fuel fired kilns will fire metal clay jewelry as an alternative to programmable kiln firing.
Prior to purchasing this type of kiln check to ensure that it will fire the type of metal clay that you work with.
The Hot Pot kiln is composed of two sections and is fuel fired. Inside the kiln is a small container to hold the fuel as well as a number of metal screens. The metal clay piece is placed on one screen and the top half of the pot is then placed on this screen with the other metal screen sitting on top of the pot.
The fuel is ignited with a match and will burn for about 15 minutes which will result in the precious metal clay piece being fully fired. When the pot is cool the finished item can be removed.
This kiln is meant to handle small clay items up to 20 grams, about the size of a US fifty cent piece.
Hot pot kilns should be used in a well ventilated area.
