Why does firing clay make it hard?
At 1832°F (1000°C) the clay crystals begin to break down and melt.
At 1922°F (1050°C), needle shaped crystals of mullite 3Al2O3•2SiO2 begin to form
, giving the fired clay strength and hardness. When mullite forms from metakaolin Al2O3•2SiO2, extra free silica is released.
