Today I started my first glaze firing with the Geil kiln. Since it's controlled by a Fuji controller the firing is really simple (once the program has been set). It allows me to do reduction firing without having to make manual adjustments during the firing.
For those not familiar with pottery kiln firing, a "reduction" firing causes the air inside the kiln to be oxygen-deficient. That causes chemical reactions in the glaze that use oxygen from the glazes. Many glazes have a different look after a reduction firing than they would have if the air inside the kiln had the "normal" amount of oxygen.
The firing takes 13 hours - I started it at 5:45 AM so it will be complete a 7:15PM today. This is a "cone 10" firing - the temperature inside the kiln will reach 2330 degrees F. After the firing the kiln cannot be opened until it cools down. It won't be sufficiently cool until some time on Friday. I'll take more pictures and post results after that.
