Pate-sur-pate means paste on paste. The design was made by painting layers of slip on the ceramic piece until a relief decoration was formed. The method was developed at the Sevres factory in France about 1850. It became even more famous at the English Minton factory about 1870. Taxile Doat, the famous French potter from Sevres, used the pate-sur-pate technique at the University City Pottery. It has since been used by many potters to make both pottery and porcelain wares.
