NC-4 feldspar is a high quality sodium / potassium / calcium aluminum silicate ground to 170, 200 and 250 mesh, for ceramic applications. Carefully beneficiated and controlled for quality, NC-4 feldspar offers high alkali content and low iron oxide content per unit of alumina. Its various grinds are tailored for specific applications.

Now called Minspar 200.
