by the pound:
Often used interchangeably with colemanite which is no longer available. A low temperature flux which helps to prevent crazing in glazes and acts somewhat as an opacifier. Often gives an opalescent quality and can give a mottled surface. Can be used as a substitute for calcium in glazes where a pink or red tint is desired or where calcium would harm colors. It can cause settling problems in the glaze bucket (add very small amounts of a deflocculant, soda ash, Darvan or sodium silicate. Also see Borax)
