Bone china is made of 50% bone ash, & 25% each of china clay and china stone. It is combined with water to make a slurry, which is then fashioned into cups, saucers, plates and so on. The pieces must be fired in a kiln at high degrees of heat (1100c to 1250c) for the china to become hard and strong. It is the bone (usually animal bone, cleaned of all meat and glue) that gives the china its transparent whiteness. The ingredients of bone china are china clay, china stone, silica, alumina, alkalies, lime and bone ash. It is fired at high of 2,300 to 2,500 degrees Fahrenheit. In the best grades of English bone china, 50% or more of the body consists of refined bone ash prepared from specially selected animal bones which are reduced to a fine powder by heat. The bone is mixed with the finest china clays and highest quality Cornish stone. Specially skilled workers are needed in the manufacture of bone china and the best and most highly skilled in the world are found in the pottery district of England.

The difference between Fine Bone China and New Bone China? from www-magnobletableware-com
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.
