Molds are one of my favorite tools in my studio. I love how quickly you can produce objects. Since graduating from Ohio State University in the spring of 2014, I’ve been trying to avoid making plaster molds in my basement studio. Carving out a dedicated plaster space isn’t ideal when my studio space is already tight. Thanks to Kari Radasch, I’ll be able to make new bisque molds quickly, effectively, and most importantly, without any plaster.
In today’s video, an excerpt from her video Low-Tech Clay – High-End Results, Kari demonstrates a really simple and interesting technique for creating a soft-curved hump mold by slumping clay into a bucket. This clip got me ready to make some new bisque molds! I can’t wait to try this out! – Ash Neukamm, guest editor
If you are someone who likes to combine throwing and handbuilding to make interesting forms, today’s video is for you. In this clip from Deborah Schwartzkopf’s Pieces and Patterns: Complex Forms from Handbuilt and Wheel-Thrown Parts, she demonstrates how she makes the super cool bottoms of her cup forms with a slab and a bisque fired mold. She then skillfully attaches the base to a bottomless wheel-thrown cylinder, which she then darts and alters to make the shape just right. The best part about this is that once you make the bisque mold for the recessed foot, you can repeat it over and over again!
Slip casting is a facet of ceramics that I am dying to explore. I love the idea of making multiples and exploring different surfaces on them. But I hadn’t thought much about the potential for decoration when colorants are added right to the casting slip. That is until Andrew Gilliatt came to town to film a DVD with us. Andrew does great work with colored casting slips and then adds even more surface detail with a variety of resists and decals. In today’s post, an excerpt from his new DVD Layers of Color: Exploring Form and Surface Pattern in Slip Cast Pottery, Andrew demonstrates how to incorporating colored slip right into the surface design.
We ceramic artists use plaster for everything from drying or wedging surfaces to stamps or molds for slip casting. But potter Lauren Sandler has been making hump molds for her work out of unfired clay. This way she doesn’t have to deal with the mess of plaster, doesn’t have to wait for her molds to dry and be fired, plus, if she gets tired of the form, she can reclaim the clay for some other use. Now, I don’t mean to diss our good friend plaster, but I do love the simplicity, speed, and versatility of this method.
My kitchen could use an overhaul, and though it is not probably going to happen for a long while, I still seem to constantly be looking for inspiration. One thing that I think would be a lovely touch to this dream kitchen is a custom tile backsplash. Of course, the most productive way of making consistent tiles is with molds. In today’s post, Gary Carlos demonstrates how he makes molds with repeatable patterns for his tiles.
Molds are a simple way to create simple or complex forms that allow you to make multiple copies of a form with little effort. When you do this, the individual forms lose their preciousness, which allows you the freedom to creatively experiment. And as you build a library of forms, you’ll find even greater flexibility as you cut and reassemble shapes in any number of configurations. Guy Michael leads you step-by-step through the entire mold making and slip casting process. By the end of his demonstration, you’ll understand the principles of making both single and multi-part molds as well as how to make your own slip and successfully cast pieces.
Building in a Box: Combining High-Tech Computer Modeling and Low-Tech Slip Casting Techniques to Make Intricate Modular Work
Though Eliza Au begins her process using three dimensional computer modeling and Computer Numerical Controlled milling, it all comes together in a good old wooden box. In today’s post, an excerpt from the March 2012 Ceramics Monthly, Eliza shares her process and casting slip recipe and author Amy Gogarty tells us a bit more about the work.

Layers of Color: Using Different Colors of Casting Slip, Resist Patterns and Decals to Create Graphical Pottery Surfaces
Today, Andrew Gilliatt explains how he arrives at his super fun surfaces by adding color in stages with colored casting slip, glaze, and decals. Plus, he shares his casting slip and a couple of glaze recipes!
This lesson plan will help students to: research historical and contemporary ceramic works that incorporate sprigging as part of the surface decoration, learn to make both bisque and plaster sprig molds, create sprig molds from found objects and from shapes and designs created in clay or carved from plaster, and to apply press-molded sprigs to leather hard forms, and press sprig molds directly into forms to stamp the surface.
