The trade names Winfield, Winfield Ware, and Winfield China werelicensed to American Ceramic Products. Whereas, the original Pasadena pottery is marked with Winfield Pasadena, and later Gabriel Pasadena. The number of the mold shape in Pasadena was nearly always incised on Winfield ware. Other Winfield artware consisted of many styles of vases, candle holders, planters, and low flower bowls.
Winfield Pottery of Pasadena was founded by Lesley Winfield Sample in 1929. Sample was born in England in 1897 where he received a wide-ranging education, including instruction in ceramics. He immigrated to southern California in the 1920s. The original site began as a studio and School of Clayworking and offered classes in the evenings. Despite limited experience in ceramic production, Sample managed to turn out an exceptional line of cast porcelain vases and bowls. Pieces were fired only once at 1950°F, in a small muffle kiln, where clay body and glaze matured simultaneously. Designer Margaret Mears Gabriel joined Sample in 1935. Gabriel brought with her new hand-painted patterns of Bamboo, Tulip, Avocado, Geranium and Citrus. Sample died in 1939, and Margaret and her husband Arthur became the owners. In 1941,they built a new 12,000-fooft factory in Pasadena with three large periodic kilns. In 1946, American Ceramic Products of Santa Monica helped Winfield produce their huge backlog of orders after the war. Winfield Pottery ceased operations in 1962, one of the many victims of cheap foreign imports and the risingpopularity of plastic dinnerware.
