Gary Jackson: Fire When Ready Pottery
A Chicago potter’s somewhat slanted view of clay & play
Categories: kiln firing

After a couple hours of the kiln firing & warming everything up, the temperature starts to build rapidly. At a certain point in the firing, you put the kiln into body reduction. Forcing the balance of the “air-to-gas” ratio out of whack. Not enough air for a stable flame. So the flames seek out extra oxygen wherever it can find it. Pulling the air from the porous pots… and reaching out through any cracks in the bricked-up kiln door! Very exciting!
