Certain glazes are good showcases for important crystallization mechanisms. This section will be expanded in future.
•The secret to cool bodies and glazes is a lot of testing.
•The secret to know what to test is material and chemistry knowledge.
•The secret to learning from testing is documentation.

- Addition of boron via Gerstley Borate produces broad, flat crystal fans. (Any borate can be used if Gerstley is not available.)
- Crystals produced by this glaze have many narrow "petals" instead of only a few (or one) large, broad petal. Aster or dandelion shaped crystals, ends are often "frilly."
