Today’s interesting fact has to do with Bone China,

Many people like the porcelain that is bone china.

The fact that is is so white and translucent coupled with the high mechanical strength and chip resistance makes it very popular.

The strength means that it can be made much thinner than other china.

But what a lot of people don't know is that the name describes what it is made from, with more than 30% made from phosphate and calcium phosphate from animal bones.

The traditional method of making it requires 50% bone ash in the preparation and to keep the iron content down, most is derived from cattle bones.
