Also, the piece can partially dry in the mold for stability. Sometimes it is a benefit that the freshly cast piece is available to decorate while soft and still supported in the mold.
Slipcasting plates in a one piece mold is a simple operation The modelmaking (simple, solid model) and moldmaking (one-part mold)) are relatively easy. An open mold is filled, a period of time elapses as the slip casts up against the working surface of the plaster mold, then the mold is inverted to drain, leaving behind the cast. One option is to drain-cast the plate like any other typical slipcast product. Here I will describe these techniques, and point out the benefits and difficulties of each Plates are slipcast either by Drain-casting or Solid-casting. In smaller-scale studio production, plates sometimes must be slipcast because that is the available technology. These kinds of forms are rarely slipcast in mass production.
In industry, flat or open ware( like plates, platters and low bowls) are usually made by some form of either pressing or jiggering…techniques that require an investment in machinery, installation, and molds or dies. Unfortunately, although there are several different ways to do this, each have their own problems and limitations. It would be great if there were a perfect way to do slipcast plates.
SLIP CASTING CERAMIC MOLDS HOW TO
How to design molds for slipcast plates, platters, shallow bowls and similar forms The article appears in the November 2021 issue, in print and on line. In early 2021, the editor of Ceramics Monthly came across this page, about slipcasting plates, and invited me to expand it into an article for the magazine.
