Why do some pots explode in the kiln?

Pots can explode in the kiln due to several factors, primarily related to moisture and trapped air. If pottery is not properly dried before firing, moisture inside can turn to steam, causing pressure to build up and resulting in an explosion. Additionally, if air pockets are trapped within the clay during shaping, they can expand and lead to breakage. Using clay that is not suited for high firing temperatures can also contribute to this issue.
