Sixth Stage: Vitrification and Maturity. The maturation of a clay body is a balance between the vitrification of the body to bring about hardness and durability, and so much vitrification that the ware begins to deform, slump, or even puddle on the kiln shelf.here is another event that clay goes through, this time as it cools. That is the sudden shrinkage of cristobalite, a crystalline form of silica, as it cools past 420â°F (220â°C). Cristobalite is found in all clay bodies, so care must be taken to cool the kiln slowly as it moves through this critical temperature.
