The major borate minerals are Colemanite and Ulexite. The geology required for borates is found in very few places in the world (mainly southern California, Chile, Turkey, Argentina, Spain, Russia). Borate minerals supply boron, a key flux in glazes, enamels, glasses, etc.

Glossary |
Boron Frit
Most ceramic glazes contain B2O3 as the main melter. This oxide is supplied by great variety of frits, thousands of which are available around the world. |
Glossary |
Borate
Borate glazes, those fluxed with the oxide B2O3, are the most common type used in ceramic industry and hobby for low and medium temperatures. |
