10 Easy Steps on How to Use Ball Clay Technique
Step 1: Preparing the Ball Clay
The first step in using the ball clay technique is to prepare the clay for use. Start by selecting a large plastic bucket to hold the desired amount of clay. Place a canvas cloth or plastic sheet over the top of the bucket and secure it with a rubber band.
Then, add the ball of clay and water to the bucket in a ratio of 1:10 (one part clay to ten parts water). Mix the clay and water thoroughly with your hands or a stick until it reaches a smooth consistency. Let the mixture sit for at least an hour before use.
Step 2: Sieving the Clay
After the clay has rested, it’s time to remove any impurities by sieving. Use a sieve or strainer to sift the clay mixture into another container. This step is crucial for removing any hard particles or debris that may hinder the workability of the clay.
Step 3: Kneading and Wedging
Next, transfer the sieved clay onto a clean, flat surface protected by a canvas cloth or a plastic sheet. Begin kneading the clay-like dough, pressing and folding to expel any air bubbles.
This process, also known as wedging, ensures the clay becomes homogenous and pliable. Keep kneading until the clay is uniformly consistent without any lumps or hard spots. Once the clay feels smooth to the touch and is no longer sticking to your hands, it is ready for shaping.
Step 4: Shaping Your Creation
With the clay now ready, begin shaping it into your desired form using your hands, a rolling pin, or a pottery wheel if creating vessels. For hand-building, you may start by flattening the clay to an even thickness and then cutting pieces to assemble.
If using a wheel, center the clay and gradually mold it into shape with the steady pressure of your hands. Remember to keep your movements fluid and to moisten your hands with water regularly to prevent the clay from sticking. This step is where your creativity truly comes into play, allowing you to bring your artistic vision to life.
Step 5: Drying Your Piece
Once you’ve finished shaping, it’s time for the drying process. Place your clay piece on a drying rack or a clean surface covered with canvas cloth to allow for even air circulation. The drying time may vary depending on the thickness of your piece and the humidity levels in the environment.
It’s essential to dry the clay slowly to avoid warping or cracking. You can cover the portion with a loose plastic sheet to control the drying rate. When the clay is leather-hard, which holds its shape but can still be carved or joined with slip, it’s ready for the next stage.
Step 6: Trimming and Refining
It’s the ideal time to trim and refine your piece at the leather-hard stage. Using a rib tool and a clay cutter or knife, carefully carve away any excess clay to refine the shape and add details.
This step is also perfect for smoothing surfaces, perfecting curves, and creating foot rings on the bottoms of pots. Take your time to ensure accuracy and symmetry. Remember that consistency is key to a balanced piece, so frequently turn and inspect your work from various angles.
Step 7: Bisque Firing
After your creation has thoroughly dried, it’s time for bisque firing, which is the first of two firings. Ensure your piece is dehydrated, as any moisture can cause cracks or explosions in the kiln. Carefully load your essay into the kiln and set it to the appropriate bisque temperature, which is usually between 1700°F (926°C) and 1940°F (1060°C).
This initial firing will turn your clay object into a complex, porous bisque ready for glazing. The firing process can take several hours to a full day, depending on the kiln and the size of your piece. Once the kiln has cooled, you can remove your piece and inspect it for defects before glazing.
Step 8: Applying Glaze
Glazing is both an art and a science, requiring careful application to enhance the aesthetics of your piece. Before you begin, ensure your bisque-fired part is clean and dust-free. Choose a glaze that complements your work, and decide whether to dip, brush, or pour it over your creation. If you’re dipping, swiftly submerge the piece into the glaze and remove it quickly to avoid over-saturation.
For brushing, apply even strokes to cover the surface, and consider layering different glazes to create unique effects. Allow the glaze to dry completely, checking for drips or uneven areas, as these will affect the final result. It’s essential to leave the bottom of your piece unglazed or use wax resist to prevent it from sticking to the kiln shelf during the subsequent firing.
Step 9: Glaze Firing
After thoroughly drying the glaze, your piece is ready for glaze firing. This final firing will solidify the ice and bring out its actual color and finish. Load your glazed piece into the kiln, not letting it touch any other objects to prevent sticking. You’ll need to set the kiln to a higher temperature than used for bisque firing, typically around 2200°F (1204°C) to 2300°F (1260°C) for stoneware glazes.
The exact temperature will depend on the type of clay and glaze you’re using. Monitor the kiln to ensure it ramps up to the desired temperature and hold it for the appropriate time to mature the glaze. Once the firing cycle is complete and the kiln has cooled, you can finally unveil your finished piece, now vitrified and glistening with a glass-like coating.
Step 10: Cooling and Inspection
Once the glaze firing is complete and the kiln has cooled sufficiently, which can take up to several hours to ensure a gradual reduction in temperature, it’s time to open the kiln and inspect your piece. Handle your creation carefully, as it will be fragile at this stage. Check for any glaze defects or unexpected changes that may have occurred during the high-temperature firing.
If the piece has a clear glaze or gloss finish, it should appear uniform and shiny without cracks or crazing. You may need to evaluate if you find any imperfections that can be sanded or refired. When satisfied with the quality, your ceramic artwork is ready to be used or displayed, proudly showcasing the dedication and skill that went into its making.
By following these ten essential steps, you can create beautiful and durable ceramic pieces that will last a lifetime.
