Wedgwood, one of the world’s most successful potteries, was founded by Josiah Wedgwood, who was considered a cripple by his brother and was forbidden to work at the family business. The pottery was established in England in 1759. The company used a variety of marks, including Wedgwood, Wedgwood & Bentley, Wedgwood & Sons, and Wedgwood's Stone China. A large variety of wares has been made, including the well-known jasperware, basalt, creamware, and even a limited amount of porcelain. Queensware, a cream-colored pottery developed by Josiah Wedgwood, was a popular dinnerware by 1765. There are two kinds of jasperware. One is made from two colors of clay, the other is made from one color of clay with a color dip to create the contrast in design. In 1986 Wedgwood and Waterford Crystal merged to form the Waterford Wedgwood Group. Most Waterford Wedgwood assets were bought by KPS Capital Partners of New York in 2009 and became part of WWRD Holdings. Some manufacturing will be transferred to Germany, Indonesia, and Slovakia. Other Wedgwood pieces may be listed under Flow Blue, Majolica, Tea Leaf Ironstone, or in other porcelain categories.
