How to fire the kilnnot kilm...killem...stove...oven...or that big thing in the back
What is a Kiln?Kilns harden ceramic bodies, heat treat steel, melt glass into crucibles, fuse layers of stained glass, melt enameling powder onto copper jewelry, fire porcelain dolls, fuse clay silver—the applications are fascinating and endless.

Typically, this is how the inside looks...Projects sit on ceramic legs that support shelving in various sizes depending on the size of the kiln

Control Box has 3 working parts that all affect firingThe temperature knob controls temp.The timer controls the length of time that the electricity is on.The cone sitter measures heat inside the kiln.

Old school cone (temperature
measuring) method...Used to use 3 different cones to measure where the temperature was... As the temperature rose, the cones
(depending on their melting point) would start to bend, indicating a specific temp. in the kiln
THE GOAL...DON’T LET THE GUARD CONE
MELT!!!

Our way...“Set it and Forget it”

Our way...
Put the desired temperature pyrometric cone in the Cone Sitter
SOURCE: http://www.skutt.com/images/
Our way...Turn the Timer to the specific firing time and flip the power switch on.
When the cone melts, the power switch drops, turning off all electricity to the kiln.
