The animal origin of bone ash in bone china is typically cattle bones. These bones are boiled to remove any flesh and then calcined to create bone ash, which is a key ingredient in bone china production.
A typical recipe for bone china clay is: China Clay 37.5% Bone Ash 37.5% Feldspar 20% quartz 5%
Bone china contains bone ash which is typically made from cow bones, although sometimes it can also come from other animals such as pigs or sheep. The bone ash is used to give bone china its distinct strength and translucency.

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. Hence where the name bone china comes from, and without this ash component, china is not really 'bone' china. It is also usually more expensive than other china, and this is justified by the processes and labour involved in its making. A piece of bone china contains at least 25% of bone ash, and this compound not only adds strength and white color to the china, but also makes it translucent. Not totally transparent, but enough for the light to pass through it.
Bone china is a type of porcelain body first developed in Britain in which calcined cattle bone (bone ash) is a major component.http://en.wikipedia.org/wiki/Bone_china
