Porcelain is a ceramic material made by heating to high temperature selected and refined materials often including clay in the form of kaolinite. One widely recognised definition is from the Combined Nomenclature of the European Communities which states porcelain is “completely vitrified, hard, impermeable (even before glazing), white or artificially coloured, translucent (except when of considerable thickness) and resonant

Raw materials for porcelain, when mixed with water, form a plastic paste that can be worked to a required shape or form before firing in a kiln at temperatures between about 1200 degrees Celsius and about 1400 degrees Celsius. The toughness, strength, and translucence of porcelain arise mainly from the formation at high temperatures of the mineral mullite and glass.

Porcelain was named after its resemblance to the white, shiny Venus-shell, called in old Italian porcella. The curved shape of the upper surface of the Venus-shell resembles the curve of a pig's back (Latin porcella, a little pig, a pig).

The composition of porcelain is highly variable, but china clay, comprising mainly or in part the platey clay mineral kaolinite is often a significant component. Other materials mixed with china clay to make porcelain clay have included feldspar, ball-clay, glass, bone ash, steatite, quartz, petuntse and alabaster.

Lots and lots of white chocolate and caramel to make it hard.

Most people don't know this,
but porcelain is actually edible.

You just have to bite down on it real hard.

Go on. TRY IT

Porcupines and cellophane, hence the name.
