Recommended for use in all ceramic applications where a fine-ground talc will develop higher fired strength than coarser grades. Used as an auxiliary flux in electrical porcelain, hotel china and sanitaryware bodies to lower manufacturing temperatures without narrowing the firing range. In semivitreous dinnerware, it decreases the moisture expansion and increases the thermal expansin, contributing to improved resistnace to crazing in glazes dinnerware.
