Laboratory porcelain is composed of a network of needle-shaped mullite crystals (3Al2O3, 2SiO2) coated with a vitreous phase.
Free quartz is only found in very small quantities. It comes in the form of fine round-headed crystals coated with a glassy phase rich in SiO2.
These products can be used up to a maximum temperature of 1200°C.
Good resistance to acids of all kinds, even at boiling point, with the exception of hydrofluoric acid. Resistance to hot concentrated bases is lower.
