ONSITE: Slab-built Boxes

Create boxes using clay slab construction techniques. We’ll cover slab rolling, accurate measuring and cutting, texturing techniques, as well as construction methods to bring it all together. Learn to build both inset and hidden and self-contained lids.Time permitting we'll also include other projects like votives, planters, and boxes.

Special Notes

  • All materials and equipment provided. Visarts has basic clay trimming tools, but you may want to augment yours after the first class. Al's classes are formatted so that the first 15-20 minutes is a critique of work in progress, the next hour is a demonstration, and the rest of class time is for individual work time. Practice is expected outside of class, but not required.

    You will receive 25 pounds of clay; additional clay is available for purchase.

    Classes are confirmed one week prior to the start date. In order to help us confirm classes, please register as early as possible.

About the Instructor

Al Pellenberg

Al has been been playing and working with mud since he was a kid, his “Play-Doh Fun Factory” was just the best toy Al ever had. Al believes he became an architect and space designer as a result of all those things that he built in my “first childhood." Over the years he have been in and out of the clay studio. He worked on the wheel for many years making bowls, cups, teapots and the lot, but the move to hand-building has been very rewarding and offering a set of challanges that combine both his architectual training and creative side in new and different ways
