- 1 psi (lb/in2) = 6,894.8 Pa (N/m2)
- Porcelain is a ceramic material made by heating selected and refined materials often including clay in the form of kaolinite to high temperatures.
- Cordierite is a crystalline magnesium aluminosilicate
- Steatite, also known as soapstone or soaprock, is a metamorphic rock, a talc-schist. It is largely composed of the mineral talc and is rich in magnesium.
- Forsterite (Mg2SiO4) is the magnesium rich end-member of the olivine solid-solution series.
