Piedmont Minerals is a division of Resco Products. It has been mining and processing a unique pyrophyllite and andalusite body of ore for over 60 years in Hillsborough, North Carolina. The white color is due to the low iron of this material. The slight expansion on firing has found a variety of uses in ceramic, brick, and refractory industries.
Several milled grades are available, as are crushed and screened grains. All grades are available in bulk, super sacks, and in 50lb bags.
