Library: Dealing With CrazingThis chapter in the lessons section of the book (and matching video at digitalfire.com) explains what crazing is, how it is related to glaze chemistry, how INSIGHT calculates thermal expansion and how to substitute some of the amounts of high expansion oxides that often cause crazing (e.g. Na2O) with lower expansion ones (e.g. MgO, Li2O, B2O3). The side effects of these substitutions are discussed and the reader is shown how to research the purpose of each of the oxides in a glaze formula. Out Bound Links
