Bone china is a type of 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

Bone china, hybrid hard-paste porcelain containing bone ash. The initial development of bone china is attributed to Josiah Spode the Second, who introduced it around 1800. His basic formula of six parts bone ash, four parts china stone, and three and a half parts china clay remains the standard English body.

Bone china is, as its name suggests, made from cow bone. The bone is finely ground into bone ash, and it is then mixed with feldspar, ball clay, quartz, and kaolin (a type of clay). ... Originating in China, the earliest porcelains used kaolin (a type of clay) and pegmatite (a type of granite).

And why is it so expensive? Lightweight yet durable, bone china is usually more expensive than other china thanks to pricier materials (yep, the bone ash) and the extra labor required to make it. But not all bone china is created equal—the quality depends on how much bone is in the mixture.

Apparently, it's all down to the smooth surface of the inside of the mug. A smooth surface keeps the natural tannins in your tea from sticking to the inside of your mug. ... And that is why tea tastes better drinking out of bone china
