Mold Making & Slip Casting Workshop with Ariel Brice

Mold Making & Slip Casting Workshop with Ariel Brice


Saturday, March 30 10am – 6pm

Sunday, March 31 10am – 6pm

Saturday, April 27 10am – 6pm


Saturday March 30th: In the morning session participants will learn about different mold types and watch as a sample mold is made. After lunch, participants will begin making their own molds with Ariel’s supervision.

Sunday, March 31st: Participants will continue making their molds with Ariel, and if time permits, you may be able to cast a second mold.

Saturday April 27th: In the morning session will watch a slip casting and press mold demonstration along with an explanation of slip and how it works to cast an object. After lunch participants will actually cast objects with the molds they made in the previous sessions and can address any questions or issues with the molds with Ariel. Participants will also have the opportunity to bring in other molds to problem solves issues.

During each session, participants would be welcome to ask questions and learn as a class about the demands of each person’s project. Participants will also have the opportunity to consult with Ariel on effective ways to build on what they have already learned to problem-solve the mold-making process.


Ariel Brice (Born Pittsburgh, PA 1980) has studied and practiced ceramics for 22 years. His 15 year passion for mold-making and casting began in 2003 as a student at Oregon College of Art and Craft and as a an artist assistant for Jim Koudelka and Stephen Gerould Lamps and Accessories. He has taught ceramics and mold-making at Virginia Commonwealth University, University of Wisconsin-Madison, ArtCenter College of Design and Loyola Marymount University. He brings experience making molds from the Netherlands, China, and the City of Industry, CA into a 3-day workshop at Fahrenheit Ceramics Studios. Join this award-winning instructor on a journey to make a plaster mold of an object and cast it in clay!



Hump molds are convex plaster forms that provide a template for slab work. An evenly rolled-out slab of wet clay can be laid over top of the hump and pressed against it. Because plaster is highly absorbent, water will be removed from the clay, and the slab will be easily released. These molds are great for creating functional wares as well as sculptural works. Through using molds, one can consistently create forms of the same dimensions, including very large forms that might be difficult to accomplish on a pottery wheel.

Slump molds, like humps molds, are plaster templates that are useful for creating reproducible forms. Slump molds are concave forms that work just like other molds in that clay is draped over the surface of the mold. With slump molds, the inside surface of a pot is exposed, while the outer face is in contact with the mold. This is opposite to that of hump molds, in which the mold is in contact with the interior side of the pot. This is ideal for some clay artists because it allows one to add elements such as a foot or a base to the piece while it is on the mold.

Drape molds are similar in concept to hump molds; however, they are typically more shallow than humps.

Sprig molds and texture slabs are used for creative and adding decorative elements to your clay pots. In ceramics, this is becoming quite popular! The plaster texture slabs allow one to create slabs of clay with detailed designs on for use in hand building. Similarly sprig molds allow one to press clay into the mold and to release a "sprig" or a decorative dimensional elements, such as a flower, leaf or animal, which can then be used on its own or added to a pot.

Slip-cast molds are multi-piece molds that are capable of making very intricate shapes and textures. When the mold’s components are joined and secured securely, slip is poured into the mold, allowed to set for a period of time and then released, where additional hand work may be done on the piece. To learn more about slip casting see below.



Slipcasting or slip casting is a technique for the production of pottery and ceramics, especially for shapes not easily made on a wheel. In slip casting, a liquid clay body slip is poured into plaster molds and allowed to form a layer, the cast, on the inside walls of the mold. Slip-cast ware should not be confused with slipware, which is pottery formed by any technique that is decorated using slip.

The technique is suited to the production of complex shapes, especially with relief decoration and thin walls. The technique can be used for small-scale production runs, to make parts for adding to pre-thrown objects (such as handles for mugs) or to produce limited edition, one-off objects.
