Porcelain deep form mortars are glazed on the outside (except for the bottom) and unglazed inside. Oversized pestles are glazed up to the grinding surface.
Physical Properties of Porcelain:
- Thermal Shock Resistance - average coefficient of expansion from 20° C 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 heat tested in our factory.
- Glaze - No softening occurs up to 1000°C, and it is extremely white.
- Resistance to Chemical Action - Resistance to acids and alkalies is excellent, except for hydrofluoric acid.
