Covered Tankard
- 112
Both stoneware, a non-porous clay body fired at a high temperature, and the use of salt to create a glaze originated in Germany, the dominant production center of coarse stoneware until the 17th century. The technique then spread to other countries including England where potters such as John Dwight discovered the secret of German salt-glazed stoneware. The process of spiraling together the soft brown and cream clays of the Covered Tankard was developed by Dwight to emulate marble. He eventually patented his techniques; his process for marbling clay is registered in a 1684 patent.
