A Beginner's Guide to Slab Pottery

You don't need a pottery wheel to make beautiful, functional ceramics. Slab building — rolling out clay and shaping it around a template — is one of the most accessible ways to start working with clay.

What you'll need to get started

• Air-dry or kiln-fired clay, depending on whether you have kiln access
• A rolling pin and slab roller guides (or just two wooden strips for even thickness)
• A printable slab template
• A craft knife for cutting and trimming
• A damp sponge for smoothing seams

Roll your slab to an even thickness

Uneven thickness is the most common beginner mistake — it causes cracking as the clay dries. Use guide strips on either side of your clay while rolling to keep the thickness consistent.

Trace and cut your template

Lay your printed template on the rolled slab and trace around it with a craft knife. Cutting cleanly now saves a lot of trimming later.

Join your seams carefully

Score both surfaces that will touch, add a little water or slip, and press firmly together. A damp sponge can smooth the seam once it's joined, which makes a noticeable difference in the finished piece.

Let it dry slowly

Drying too fast is another common cause of cracking. Cover your piece loosely with plastic for the first day or two so it dries evenly, then uncover it gradually.
