Firing day nerves

Firing day. Even after twelve years, my stomach turns a little. Inside the kiln, water leaves the clay, then the glaze melts into glass. The worst thing you can do is open the lid too early, because sudden cold cracks pots. So I make a rule. The kiln cools overnight, and I go for a walk. Your one thing to try? Write your firing notes before you open the kiln, so you remember what you hoped for.
