Bone china dishes have been around for a very long time and can be found in most china buffets, old and new. Several processes are involved in the making of bone china, but the ingredient that sets it apart from fine china, is the component of bone ash that is included in its manufacture.
Bone china is a type of soft-paste porcelain that is composed of bone ash, feldspathic material and kaolin. It has been defined as ware with a translucent body containing a minimum of 30% of phosphate derived from animal bone and calculated calcium phosphate. Developed by English potter Josiah Spode, bone china is known for its high levels of whiteness and translucency, and very high mechanical strength and chip resistance.
