Blanc-de-chine

Blanc-de-chine is a French term generally used to refer to undecorated ivory white porcelain pieces made for export by the Dehua  kilns in the Fujian province, during the 17th-18th centuries. Many early European porcelain factories copied the style. Blanc de Chine wares are covered with a clear glaze which seamlessly seems to adhere to the porcelain body. Reference: Gotheburg.com
