Mason's Ironstone

Charles James Mason registered the patent name ‘IRONSTONE’ in 1813 for the ‘Improvement of the Manufacture of English Porcelain, IRONSTONE PATENT CHINA:’ Patent number 3724. The name was soon adopted by competitors, whom were using similar materials.

Contrary to popular belief, Mason’s Ironstone does not contain iron! The name is derived from its ‘iron-like’ strength and durability.
