Bone China, referred to as bone China, is produced in Britain. It is generally believed that the first Englishman who successfully made bone China was Josiah Spode (1755- 1827). Josia Spode directly mixed calcined bone with porcelain clay and mineral flux to become the traditional raw material of hard porcelain, which was successfully tested in the early19th century. Later, he began to systematically study the formula for producing bone China. At the end of 182 1, the ratio of ashes to porcelain stone was "standardized". At that time, it was thought that porcelain with feldspar as flux and 46% ash was the best product.
