“Imperial Porcelain” ceramic balls for stoves are made of special mullite-corrundum porcelain. This porcelain is 90% alumunium oxide Al2O3, which is the knowingly hard corrundum.
· Imperial Porcelain has a Mohs hardness of 9 and is therefore second only to diamond.
· Its operating temperature is 1650°C, which is almost twice that of jadeite.
· Its heat capacity is comparable to that of jade and reaches up to 1.1 kJ/(kg°С)
Thanks to these properties, ceramic balls do not crack and do not change in color due to prolonged exposure to cyclical temperature drops.

Specific heat capacity: 1,1 kJ/kg°C
