The Quartz Corp feldspar is ideally suited for sanitary ware applications and offers the level of fusibility needed for to the markets technical constraints.

The Minspar™ product line is a carefully controlled, high quality sodium/ potassium/ calcium aluminum silicate ground to specific particle size. Each product offers low iron and titanium oxide and high alkali oxide content per unit of alumina.

Minspar™ 170 and 200 are both well suited to serve as the fluxing agent in a sanitaryware formula. Minspar™ 250 is a carefully beneficiated grade that is particularly suited for use in glaze.
