Royal Worcester is one of the oldest English brands of porcelain in existence as of 2014. The company is part of the Portmeirion Group and sells tableware and gifts.
The company was founded in 1751, when two Englishmen, a doctor and an apothecary, secured investments for a new method of making porcelain. In 1788, King George III granted the company a "royal warrant of appointment," adding to its prestige. Although the company has a two-century history, older Worcester egg coddlers are not especially valuable.
