Barium carbonate is commonly used in crystal matte glaze recipes as BaO readily forms crystalline phases during cooling. Barium can act to initiate crystal development in other che mistry. For example, metallic glazes can benefit by the addition of some barium carbonate. Barium carbonate can also be added to clay bodies in small amounts (0.2-0.8%) to reduce fired surface scumming/ excess soluble salts. NOTE: This product does not ship to California.
