Masons Pottery
Ironstone was patented by the British potter Charles James Mason in 1813. It is a type of vitreous pottery and often classed as earthenware. It was developed as a as a cheaper alternative to china. There is no iron in ironstone; its name is derived from it's notable strength and durability enabling objects of considerable size to be made of it. After the East India Company ceased the bulk importation of Oriental porcelain in 1791, James Mason began to manufacture his own wares. His Ironstone closely replicated the Chinese ceramics that the wealthier classes had been buying throughout the eighteenth century.
Today Masons ironstone is very collectable. The most common early Mason’s mark, used from 1813-25, is ‘MASON’S PATENT IRONSTONE CHINA'. This mark was still used until the closure of the Wedgwood factory in 1998.
