Slab Building Demo - Get Quicktime

Video Clip 1 - Rolling the Clay
The slab roller is a table with a double-barrel roller, which can be turned to squeeze clay between the rollers into a slab of uniform thickness. John alters the thickness by adjusting the distance between the two rollers.

Video Clip 2 - Cutting and Moving the Clay Forms
John removes the texture left by the canvas cloth using a sponge and a long metal spatula to smooth the surface and remove air bubbles. The smoother the surface, the easier it will be to remove the glaze stain applied later in the process.

Video Clip 3 - Surface Decoration
After smoothing the surface again, John places an old potato bag on top of the clay, and uses a rolling pin to indent the fibers into the clay's surface.

Video Clip 4 - Drying and Firing Greenware
Drying the slab requires about 24 hours, and then the greenware, or unfired, piece can be bisque fired to prepare it for glazing. Jan has waxed the bottom of the bisque-fired piece so the glaze will not adhere to it, preventing the piece from sticking to the kiln shelf during firing.

Video Clip 5 - Applying Glazes
John stirs the stain for a uniform consistency. Jan dips the object into the stain on half at a time, allowing the stain to run toward the center of the object. The stain fills the grooves left by the potato bag fibers. Using a wet sponge, Jan removes the stain from the middle of the object. The stain removes easily because of the smooth surface.

John emphasizes the importance of allowing the clay and glazes to mature properly during firing, so that the finished piece reflects the convergence of the clay body and the glazes in a chemical and physical process.
