Sadler & Green
John Sadler and Guy Green were partners in a printing firm in Liverpool. In 1756 they unsuccessfully applied for a patent to print onto the glazed surface of pottery. Although they did not receive a patent, they continued printing on delftware, porcelain and creamware. They had a mutually exclusive arrangement with Josiah Wedgwood – he sent them creamware to be printed, they agreed not to print on creamware from other manufacturers. This agreement was entered into in about 1762 and continued after Sadler’s death in 1789 probably until the death of Josiah Wedgwood in 1795.
Salopian china warehouse
The Salopian China Warehouse was the London retail establishment of the Salopian China manufactory in Caughley, Shropshire. The name Salopian derives from Salopia the Roman name for the county of Shropshire. The London business was in Portugal street in a the former “Lincoln’s Inn Old Playhouse” theatre. The building was put to various uses before being adapted as a “China warehouse” where the Caughley porcelains could be displayed and sold to fashionable London customers. The premises was leased by Ambrose Gallimore and Thomas Turner, and then by Turner alone. After his death the Caughley factory moved its retail arm to Whitefriars and from 1794 Josiah Spode II leased the building finally buying the freehold in 1802.
salt-glazed stoneware
Pottery can be glazed with several different glass or glaze forming materials. Salt can be used as a glazing material in the production of stoneware. When pottery is made, during its first fire, at the height of the firing salt is thrown into the kiln, it vaporizes and sodium from the salt combines with alumina and silica which are present in the clay creating a glassy sheen on the surface of the ware. Salt-glazed stoneware was introduced in Germany in the late 13th -14th century. Staffordshire was famous in the 18th century for its fine white salt-glazed stoneware table wares. White salt-glazed stoneware continued to be produced into the last quarter of the 18th century, was its popularity declined after the introduction of creamware in the middle of the century.

stone china
Stone china is a dense hard white ceramic that does need a glaze. Its smooth surface results from the high percentage of glass forming material in the body recipe. Patented in 1800 by William & John Turner, their version was known as “Turner’s Patent”. The Turner factory closed in 1806. The factory of the mason family first produced their famous “Ironstone china”, with Spode producing his own “Stone China” about 1813. These later version were usually decorated and glazed and resembled dense, hard earthenware.
