Why does it take so long to complete a firing cycle with clay?

Answer 1

Completing a firing cycle with clay takes time due to the gradual heating and cooling processes required to prevent cracking and ensure even firing. The kiln must slowly raise the temperature to allow for proper maturation of the clay and glaze, which involves chemical transformations. Additionally, cooling down too quickly can lead to thermal shock, so the kiln must also cool down slowly. This careful regulation of temperature throughout the cycle is crucial for achieving the desired strength and finish of the final product.
