How long should a piece dry before bisque firing?

A piece should typically dry for at least 24 to 48 hours before bisque firing, depending on its size and thickness. It's important to ensure that the clay is bone dry to prevent cracking or exploding in the kiln. You can check for dryness by feeling the surface; it should be cool to the touch and no longer feel damp. Proper drying is crucial for a successful bisque firing.
