Hand-Building Ceramic Techniques

Gather all necessary materials such as clay, rolling pins, a canvas or slab mat, wire clay cutter, rib tools, sponges, and slip (clay mixed with water). Prepare a clean, flat workspace.

Begin by wedging the clay to remove air bubbles and ensure an even consistency. This process involves kneading the clay with a rocking motion.

Roll out the clay into an even slab using a rolling pin. Use guide sticks on either side of the clay for uniform thickness. Once rolled, the slab can be cut and assembled into shapes and forms.

Start by rolling a ball of clay. Insert your thumb into the center, then pinch and rotate the clay to form a pot. Thickness should be even for the pot to hold structural integrity.

Roll out long strands of clay, ensuring even thickness throughout. Layer and join these coils to build up the walls of a pot or other structure, smoothing the sides as you go.

When attaching two pieces of clay, score both surfaces, apply slip to act as a glue, and then press the pieces together. Blend the seams using your fingers or a rib tool for a smooth finish.

Allow your piece to dry slowly to leather-hard before further refining the shape. Cover it with plastic if necessary to control the drying rate.

Once leather-hard, refine the shape using various rib tools, carving tools, and sponges. Smooth out imperfections and ensure stability in the form.

Allow the refined piece to dry completely. This bone-dry stage can take several days, depending on humidity and temperature.

Fire the bone-dry piece in a kiln to the bisque temperature specific to your clay body. This will make it strong and ready for glazing.

Apply glaze to your bisque-fired piece following the manufacturer's instructions. Be mindful of glaze thickness and drying times.

Place the glazed piece back into the kiln for the final firing. Once done, it should be fully vitrified and functional.

Different types of clay (earthenware, stoneware, porcelain) require different firing temperatures and handling. Choose the type that best suits your project.

Always work in a well-ventilated area when handling clay and glazes. Wear protective gear as necessary, especially during the firing process.

The thickness of the clay and the humidity in the environment will affect drying times. Thicker pieces and higher humidity result in longer drying times.

Always test glazes on a small sample piece before applying to your final work to ensure you get the desired finish and color.
