Formula: BaCO3
Used in glazes as the typical source for Barium. It has limited use
due to its lack of reactivity and toxicity. In low fire glazes (cone
06-5) it promotes matt (sometimes dull) finishes. However, at high
temperatures (cone 8-13), it is a powerful flux. It is used in clay
bodies to control scumming by rendering sulphates insoluble.
