Red is the color of love, as well as danger and sin. Red has also been a symbol of wealth and status. Chinese potters of the Ming Dynasty created red-glazed porcelains and European ceramic artists strived to emulate the rare beauty of their oxblood Sang de Boeuf glazes in the early 1900s. Royal Doulton, Ruskin and Moorcroft experimented with high-temperature firings, starving the kiln of oxygen to develop copper red glazes, which became known as flambé after the French for flames.
