The Pyrotrol group of mineral products offers a controlled blend of milled Andalusite/Pyrophyllite ores designed to control strinkage in whiteware ceramic applications. Alumina contents are controlled to meet certain specifications. Pyrotrol produces an excellent kiln car wash and is an inexpensive coating material for facebrick production.
