Bone China is dense and delicate. It’s translucent and famous for its warm creamy white colour.
Bone China comes from England where it first appeared in the region of Stock on Trent during the eighteenth century. It contains bone ash
(fired, pulverized cattle bones) as its main ingredient.

Biscuit firing (Temperature: 1 220 – 1 250°C):
During biscuit firing, Bone China, is very sensitive to deformation. Consequently, Bone China flatware has to be supported by a profile setter during this biscuit firing process.
