When instructor Tom Spleth did his slide night at the beginning of his eight-week class in making ceramics from plaster molds, he projected slides of his work on the wall, then poured plaster on a large piece of masonite, cued some lovely music, and demonstrated his method for making a sculptural form from drying plaster. Staff member Mark Boyd was on hand with a camera and made this beautiful 5-minute video titled Fluid Form.
A technical note on what Tom is doing: The plaster form he makes in the video would be the first step in the creation of a hollow, porcelain sculpture or vase. After the plaster form dries, Tom refines it with scrapers and other tools, then he makes a multipart plaster mold from the form. The next step is to pour clay slip into the mold, let it sit for a bit and then pour it out again, leaving layer of slip clinging to the inside of the mold. The mold is then opened and the clay form inside can be glazed and fired. –Robin Dreyer
