If you are a collector of China then you most certainly have been in contact with Bone China. But what is Bone China actually? Simply put its a type of China created from a Porcelain that contains Bone Ash and other materials.
Bone China was created in the early 1790's by Josiah Spode who was an English Potter. He further developed a formula originally created by Thomas Frye. Josiah's formulation included 6 parts bone ash, 4 parts china stone and 3.5 parts china clay. The bone ash is created from cattle bones because they have a lower content of iron. This formula is still used as the base for all bone china. Josiah also had great success with his pottery company “Spode” that he founded in 1767 which is still a popular brand.
