Making plates with hump and slump molds is a good way to develop basic slab-making and decorating techniques. After a few hours of practice, anyone can learn to roll out a uniform slab and experience the thrill of working with different stages of clay, and learn what that clay is capable of at each stage.
You can familiarize yourself with simple hump and slump molds, and begin to consider the function and shape of a part. And when the project is finished, you will have a set of useful plates to eat or to give as gifts. You can easily buy slumping mold through online sites.
To start, spread one fourth thick slab of clay on a canvas. Roll 2-3 times on each side, then remove the slab from the canvas and flip it over to continue rolling.
When it reaches the proper thickness, carefully lift the slab and allow it to harden until set. The clay slab should be flexible without cracking, but not so wet that fingerprints are visible. Smooth the edge of your plate by sliding your finger along the edge with firm pressure; or use a damp chamois or sponge.
Place plates on hump molds or gently press down on settling molds to form an evenly curved shape. Then remove the dishes from the pans and check that they sit firmly on a flat table without rocking; and they stack very well. Plate sets can be linked by theme, concept, color, size, or image position.
Soak the stencil in water until it is wet but not soaked yet, and place it on a paper towel to remove excess water. Place the template on the clay plate and press it down with a damp sponge. The paint glides over the stencil, then carefully removes it from the plate. Voila!
