A Grolleg based porcelain vs. a ball clay and American kaolin porcelain


Wednesday 25th July 2012

These mugs were fired in the same kiln load at insight-live.com/glossary/125">cone 10R and have the same clear glaze, G1947U. The mug on the left is a Grolleg kaolin (52% Grolleg kaolin, 24% silica and 19% Mahavir feldspar, 5% bentonite). The one on the right is 15% M23 ball clay, 40% #6 Tile kaolin, 15% Nepheline, 25% silica, 3% bentonite. Clearly, the Grolleg porcelain fires so much whiter.
