## Understanding the Essentials
Before diving into the practical steps, let’s cover the fundamental tools, materials, and concepts involved in wheel throwing.
### Tools and Materials
* **Pottery Wheel:** The heart of the operation! Look for a sturdy wheel with variable speed control. Both kick wheels and electric wheels are viable options, each with distinct advantages. Electric wheels offer more consistent speed control, while kick wheels promote a more organic connection to the process.
* **Clay:** Earthenware, stoneware, and porcelain are common clay types. For beginners, stoneware is often recommended due to its forgiving nature and durability. Ensure the clay is properly wedged to remove air pockets.
* **Water Bucket:** Clean water is crucial for lubricating the clay and keeping your hands and tools moist.
* **Sponge:** Essential for absorbing excess water and smoothing the surface of the clay.
* **Towels:** Have plenty of towels on hand for drying your hands and cleaning up spills.
* **Needle Tool:** A sharp, pointed tool used for trimming the base and creating drainage holes.
* **Rib:** A flexible tool made of wood, metal, or plastic, used for shaping and smoothing the pot.
* **Wire Cutter:** Used for cutting the pot off the wheel head.
* **Calipers:** Helpful for measuring the diameter of the pot, ensuring consistency if you’re making multiple pieces.
* **Apron:** Pottery can be messy! Protect your clothing with a durable apron.
* **Optional Tools:** Various other tools can enhance your pottery experience, such as trimming tools for refining the foot of the pot, fettling knives for removing excess clay, and decorating tools for adding texture and patterns.
### Key Concepts
* **Wedging:** This crucial step involves kneading the clay to remove air pockets and create a uniform consistency. Air pockets can cause explosions during firing, so proper wedging is essential.
* **Centering:** The process of getting the clay perfectly centered on the wheel head. This is the foundation of all wheel throwing. Without a properly centered mound of clay, it’s impossible to create a symmetrical pot.
* **Opening:** Creating a hole in the center of the centered clay mass.
* **Pulling:** Raising the walls of the pot by applying upward pressure.
* **Shaping:** Using your hands and tools to refine the form of the pot.
* **Trimming:** Refining the foot of the pot after it has leather-hardened.
* **Firing:** The process of heating the clay to a high temperature in a kiln, transforming it into durable ceramic.
## The Step-by-Step Guide: Making Your Clay Pot
Now, let’s embark on the journey of creating your clay pot! Follow these steps carefully, and don’t be discouraged if it takes practice. Pottery is a skill that develops over time.
**Step 1: Wedging the Clay**
Wedging is paramount. There are several wedging techniques, but the most common are the ram’s head method and the spiral method. The goal is to remove air pockets and create a consistent clay body.
* **Ram’s Head Wedging:** Form the clay into a cone shape. Push down and forward with your palms, forcing the clay outward. Rotate the cone slightly and repeat the process until the clay is smooth and free of air pockets. It resembles the head of a ram, hence the name.
* **Spiral Wedging:** Start with a ball of clay. Use your hands to roll the clay into a spiral shape, pushing down and forward. Rotate the clay and repeat the process. This method is particularly effective for removing air pockets. It’s also known as the “English” or “Plunge Cut” method.
Regardless of the method you choose, wedge the clay thoroughly until it’s smooth and pliable. A well-wedged clay body will be easier to center and throw.
**Step 2: Preparing the Wheel and Clay**
* **Splash Pan:** Ensure your wheel’s splash pan is properly seated and clean. The splash pan helps contain water and clay splatters.
* **Wheel Head:** Lightly wet the wheel head. This will help the clay adhere to the surface.
* **Clay Amount:** Take a ball of wedged clay, about 1-2 pounds for a small pot. The amount of clay will depend on the desired size of your pot.
* **Cone Shape:** Form the clay into a cone shape. This shape is easier to center than a ball.
**Step 3: Centering the Clay**
Centering is arguably the most challenging part of wheel throwing, but it’s essential for success. Here’s a detailed breakdown:
* **Placement:** Firmly throw the cone of clay onto the center of the wheel head. Use a good amount of force to ensure the clay adheres securely.
* **Speed:** Start the wheel at a slow to medium speed. Too fast, and the clay will be difficult to control.
* **Cone Up:** With wet hands, cone the clay up by applying pressure with your palms and fingers. The goal is to lift the clay into a cone shape, keeping it centered.
* **Cone Down:** Once the clay is coned up, cone it back down by applying pressure from the top and sides. This compresses the clay and helps remove any remaining air pockets.
* **Repeat:** Repeat the coning up and coning down process several times. This is the key to centering the clay.
* **Final Centering:** With the wheel spinning at a moderate speed, use your left hand to brace against your side for stability. Place your left hand on the side of the clay and your right hand on top. Apply firm, even pressure to compress the clay into a stable, centered mound. Your elbows should be tucked into your body for stability.
* **Check:** The clay is centered when it no longer wobbles and feels stable and balanced. If it’s still wobbly, repeat the centering process until it’s perfectly centered.
**Troubleshooting Centering:**
* **Clay is wobbling:** This indicates that the clay is not yet centered. Continue coning up and coning down, applying consistent pressure.
* **Clay is shifting:** This means you’re applying too much pressure on one side. Adjust your pressure to be more even.
* **Clay is collapsing:** You may be applying too much downward pressure. Ease up on the pressure and focus on compressing the clay from the sides.
**Step 4: Opening the Clay**
Once the clay is centered, you’re ready to open it up.
* **Thumb Placement:** With the wheel spinning at a slow speed, use your thumb (or index and middle fingers) to press down into the center of the clay. Apply steady, even pressure.
* **Depth:** Press down until you’re about halfway to three-quarters of the way to the wheel head. Be careful not to go all the way through.
* **Widening:** Use your fingers to widen the opening to the desired diameter of your pot’s base. Keep the opening centered.
* **Smoothing:** Use a sponge to remove any excess water from the inside of the opening and smooth the bottom surface.
**Step 5: Pulling Up the Walls**
Pulling up the walls is the process of raising the clay to create the height of your pot. This requires patience and practice.
* **Hand Position:** With the wheel spinning at a slow to medium speed, place your fingers inside the opening and your thumb on the outside wall of the pot. Your fingers and thumb should be aligned vertically.
* **Applying Pressure:** Gently squeeze the clay between your fingers and thumb, applying upward pressure. The goal is to thin the wall and raise it slightly.
* **Consistent Motion:** Move your hands upward in a smooth, consistent motion. Avoid jerking movements.
* **Repeat:** Repeat the pulling process several times, gradually raising the walls of the pot. Each pull should raise the wall a little higher.
* **Compressing the Rim:** After each pull, compress the rim of the pot with your fingers to prevent it from cracking. This also helps to thicken the rim and give it a more finished look. Use a sponge to keep the rim wet.
**Troubleshooting Pulling:**
* **Walls are too thin:** You’re applying too much pressure. Reduce the pressure and focus on raising the walls gradually.
* **Walls are collapsing:** You may be pulling too quickly or not providing enough support. Slow down the pulling process and ensure your hands are providing adequate support.
* **Walls are uneven:** You’re applying uneven pressure. Focus on maintaining consistent pressure between your fingers and thumb.
* **Rim is cracking:** The rim is drying out too quickly. Keep the rim wet with a sponge and compress it regularly.
**Step 6: Shaping the Pot**
Once the walls are pulled up to the desired height, you can begin shaping the pot.
* **Rib Usage:** Use a rib to smooth the surface of the pot and refine its shape. Hold the rib at a slight angle and apply gentle pressure as the wheel spins. This will help to compress the clay and create a smooth, even surface.
* **Hand Shaping:** Use your hands to gently shape the pot. You can create curves by applying pressure from the inside or outside. Be careful not to distort the shape of the pot.
* **Consider the Form:** Think about the desired form of your pot. Do you want a wide, open bowl or a tall, narrow vase? Use your hands and tools to achieve the desired shape.
**Step 7: Finishing the Rim**
The rim is an important detail that can significantly impact the overall look of your pot.
* **Refining the Edge:** Use your fingers or a sponge to refine the edge of the rim. You can create a rounded rim, a squared-off rim, or a beveled rim.
* **Smoothing:** Ensure the rim is smooth and free of any cracks or imperfections. This will make the pot more comfortable to use and prevent it from chipping.
* **Adding a Lip:** You can add a small lip to the rim to make it easier to pour liquids. Use your fingers or a small tool to create the lip.
**Step 8: Cutting the Pot Off the Wheel**
Once you’re satisfied with the shape of your pot, it’s time to cut it off the wheel.
* **Wire Cutter:** Use a wire cutter to separate the pot from the wheel head. Hold the wire taut and pull it through the clay at the base of the pot.
* **Smooth Removal:** Carefully lift the pot off the wheel head. Avoid touching the sides of the pot, as this can distort its shape.
* **Placement:** Place the pot on a bat (a removable disc) or a ware board (a piece of plywood or plaster) to dry. This will make it easier to move the pot later.
**Step 9: Drying the Pot**
Drying the pot slowly and evenly is crucial to prevent cracking.
* **Slow Drying:** Cover the pot loosely with plastic wrap to slow down the drying process. This will help to prevent the pot from drying too quickly and cracking.
* **Even Drying:** Turn the pot regularly to ensure it dries evenly. This will prevent warping.
* **Leather-Hard Stage:** The pot is ready for trimming when it reaches the leather-hard stage. This is when the clay is firm but still pliable. It should feel like leather to the touch.
**Step 10: Trimming the Pot**
Trimming is the process of refining the foot of the pot and removing any excess clay. This is done when the pot is leather-hard.
* **Centering:** Center the pot upside down on the wheel head. Use small pieces of clay to secure it in place.
* **Trimming Tools:** Use trimming tools to remove excess clay from the foot of the pot. Start with a larger tool for removing larger amounts of clay and then switch to a smaller tool for refining the shape.
* **Foot Ring:** Create a foot ring by trimming away the clay around the base of the pot. The foot ring should be wide enough to provide stability but not too wide that it detracts from the overall design.
* **Smoothing:** Smooth the foot of the pot with your fingers or a damp sponge. This will remove any sharp edges and create a more finished look.
**Step 11: Bisque Firing**
Once the pot is bone dry it’s ready for its first firing, the bisque firing.
* **Kiln Loading:** Load the kiln carefully, ensuring that the pieces aren’t touching.
* **Firing Schedule:** A typical bisque firing schedule involves slowly raising the temperature to around cone 06-04 (approximately 1830-1945°F or 1000-1063°C). The slow firing is crucial for ensuring any remaining moisture evaporates safely, preventing explosions.
* **Cooling:** Allow the kiln to cool completely before opening it. This can take several hours or even overnight.
**Step 12: Glazing**
Glazing adds color and a waterproof surface to your pottery.
* **Glaze Selection:** Choose a glaze that is compatible with your clay body and firing temperature.
* **Application Methods:** There are various glazing methods: dipping, brushing, pouring, and spraying. Dipping is a common and efficient method for smaller pots.
* **Multiple Coats:** Apply multiple thin coats of glaze, allowing each coat to dry before applying the next. This helps to ensure even coverage and prevents runs.
**Step 13: Glaze Firing**
The final firing, the glaze firing, vitrifies the glaze and fuses it to the clay body.
* **Kiln Loading:** Load the glazed pieces carefully, making sure they don’t touch each other or the kiln shelves (use stilts if necessary).
* **Firing Schedule:** The glaze firing temperature depends on the type of glaze you’re using. Follow the manufacturer’s recommendations.
* **Cooling:** Allow the kiln to cool completely before opening it. The cooling process is just as important as the firing process, as it allows the glaze to develop properly.
