GF-78 washed clay is a range of very white firing clays for vitreous tile applications such as whole body in porcelain tiles, micronized tiles and top charge and speckle in granito. 

They are available in cake form andfeature good particle size distribution, relatively low iron and titanium and offer good strength characteristics.

GF-78 washed clay are processed and sized under strict internal quality assurance programs. 

The result is consistent chemistry with uniform particle size distribution for predictable firing performance.
