What is Bone China?
Bone China was first developed in the 18th Century in England and has established its reputation as the finest and most prestigious chinaware.
Bone China contains “bone ash” in addition to the main raw materials of porcelain (clay, feldspar and kaolin). Unlike porcelain, “frit glaze” is applied on the surface of Bone China, which is fired at a relatively low temperature. These differences make Bone China unique and prestigious among ceramics.
About Bone Ash
Back in the 18th Century, English potters were struggling to produce good white porcelain. They added bone ash made from cow bones to their raw material, and succeeded in making what is now known as Bone China. Currently the bone ash used in Bone China is calcium phosphate, which is made from byproduct of gelatin. Calcium phosphate is a safe material used for toothpaste, baking powders and supplements.
