Is Is Possible To Calcine Your Own Kaolin?

When you calcine kaolin, you burn off the chemical water as well as any other organics- the stuff that's listed as L.O.I (Loss On Ignition) when you look at the makeup of a clay. So basically you're pre-shrinking the clay. In the case of kaolin, you're getting rid of about 15% shrinkage, which is significant if you've got a glaze or such that's ...
