Bone china is made by adding bone ash to a mixture of clay, feldspar, and quartz. The bone ash, which is derived from animal bones, contributes to the whiteness, translucency, and strength of the final product. This unique combination gives bone china its characteristic properties, making it a popular choice for fine tableware.
You put clay in the kiln when the clay is at the bone dry stage.
When you attach a piece of plastic clay to bone dry clay, the two will not bond effectively. Bone dry clay is no longer plastic and lacks moisture, meaning it won't adhere to the plastic clay properly. Over time, the plastic clay may separate from the bone dry clay, especially during firing, as they have different shrinkage rates and moisture content. To ensure a better bond, it's essential to score and slip the surfaces before joining them.
Kaolin is the main type of clay in porcelain. Bone china is a porcelain body that has an inclusion of bone ash, calcined animal bone (calcium phosphate), which adds hardness and translucency.
Clay is a raw material. I thought it wasn't a compound.
Grog is the material usually added to clay to minimize shrinkage. Grog is ground fired clay and it adds strength to the body as well as minimizing shrinkage.

what is a native compound made of clay
Bone china is made out of clay, not bones. Actually, bone china is made out of clay AND bone ash, which is the white ash produced from the burning of bones in open air. I would assume any type of bone could be used.
Many types of clay are known; see the link below.
The 'bone' in bone china indicates that the china clay has been mixed with bone ash.
