Keywords:  kiln, pottery, silica, cracks, cooled
The breaking or cracking of pots while cooling after firing-caused by cold air getting into the kiln.
The cracking that results from a fired object being cooled too quickly.
Cracks, which occur on pottery during the heating or coolinf cycle of the firing. They are usually caused by the silica inversion at 1063°F (Alpha to Beta phase) or the Crystobalite (one of the 'phases' os silica) inversion at 428 °F in both cases there is an expansion and contraction, of around 2-3%, in the heating and cooling cycles.
