In a couple of old TV shows, I’ve seen characters make a clay sculpture and stick it right in the kiln. NOoooo!!! The clay must be dried very slowly, covering it, then letting it breathe; turning each piece over, repeat. If they are’t dried carefully, they can warp or split. And the clay must be absolutely dry before firing, because remember what a tiny drop of moisture does inside a hard corn kernel when it gets hot? That’s what would happen in the kiln.
More next week.
