• Thermal shock resistant - average coefficient of expansion from 20 to 200°C is 3.56 x 10^-5, gradually increasing to 4.69 x 10^-5 at 1050°C
• Every batch of porcelain is factory heat tested
• Glaze is extremely white and no softening occurs up to 1000°C
• Chemically resistant - Resistance to acids and alkalies is excellent, except for hydrofluoric acid
