Ironstone China - Credit for the invention of ironstone china is generally accorded to Charles Mason in 1813. Charles Mason was one of the two sons of Miles Mason who founded the Mason works in 1802, and ran the business with his brother George Mason.

Ironstone was a heavy hard earthenware which was slightly translucent, its strength supposedly coming from a very small quantity of iron slag added to the mixture. The additional strength enabled the company to make larger objects that were not susceptible to breakage.

The company manufactured dinner wares, toilet sets, tureens, jugs and so on, and the most popular patterns were blue and white, floral and Oriental Imari style colours.

The trade name "Patent Ironstone China" was registered by the company in 1813, but the patent was only valid for 14 years and was not renewed, enabling other potteries to use the word "ironstone" in describing their wares.

Mason wares are generally well marked with "Mason's Patent Ironstone China" .
