Spode china is a popular type of English porcelain. It was first made in a factory founded in 1770 by Josiah Spode (1733-1797) near Stoke-on-Trent in Staffordshire. Spode has been credited with inventing bone china. To create bone china, potters add bone ash to the hard paste of stone and clay traditionally used to make porcelain. Bone china has a translucent, ivory-white appearance and does not chip easily. By 1796, Spode had developed English china, a porcelain suitable for dinnerware, which is thought to be the first bone china. His son, Josiah (1754-1827), was successfully marketing bone china by about 1799.
