The holidays found me down in North Carolina, where I left the old electric kiln I picked up off of Craigslist. Finally some time to tackle the electric to gas conversion! I brought along a few boxes of dried pots packed in newspapers for a test firing.
Well, I was unable to make it to the
store to get kiln-building supplies for a few days, so I impatiently stashed
a batch of pots under the grate in the house
fireplace and started firing with wood. The pots were all at least a few months
dry and the hickory fire provided a fairly
gradual warmup.
I kept adding a log or two every half hour and raking the
embers around the pots till they were nested in about 6 inches of ash and
coals. After five hours, I let the fire die down and the next morning, I pulled
out a couple bisqued pieces and a number of not-so-hard examples (those
that sat around the outside edges). I rotated the latter to the inside and went ahead and fired again, adding a few extra pots, with about the same results. The
center area (ca. 10 by 6 inches) under the grate made it to bisque temperatures
but fell off sharply on all sides- pretty much what you’d expect.
