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

A couple hours into the firing this morning, you could start to see some of the “color” inside the kiln. It takes a long time for it to start really heating up… think about all of the pots, shelves & bricks that need to absorb the heat too!!! At certain intervals, you need to adjust the kiln in terms of air & gas ratios. This glowing moment is when I put the kiln into “body reduction” by throwing the balance out of whack with not enough air for a good stable flame. The flames need to seek out air anywhere they can… through the bricks, or more importantly from the porousness of the pots inside… thus sealing them up solid & vitrified!
