Message:: [QUOTE="2manybooks, post: 7193457, member: 8267"]There is "slip decorated" pottery, which is a traditional technique where clays of different colors are mixed as a thick liquid - a "slip" - and applied like a paint. And there is "slip cast" pottery, which is a method of mass producing ceramics using molds. A slurry of clay (also referred to as a slip) is poured into a mold (made of 2 or more pieces), allowed to set, and the excess slip poured back out. Once the clay is firm enough the mold can be taken apart and the piece is allowed to dry further before firing. Slip cast pottery may show a raised "mold line" where the pieces of the mold were held together. Mold lines may be smoothed out on the outside of a pot, but can often still be felt on the interior if the maker has not bothered to finish the interior surface. Traditional Pueblo pottery is hand built with a coiling technique (no use of molds), and decorated with clay slips before firing. There seems to be some confusion about "R. Galvan", some sources associating the name with pottery from Mata Ortiz, some sources suggesting the name is associated with mass produced SW style pottery.
