Creating beautiful pottery on a wheel requires mastering a few key techniques, and two of the most critical ones are opening and pulling up walls. To open your clay on the wheel, you first need to center it properly, creating a stable base for your pot. Once your clay is centered, you can push down with your thumbs to create the initial opening. This step sets the stage for the rest of your pottery piece.
Now comes the exciting part: pulling up the walls. This involves a delicate balance between your hands and the clay. With your hands cupped around the base of the clay, you apply gentle, even pressure as you slowly pull upwards. Keeping your hands steady helps to shape the clay into a smooth cylinder, providing a foundation for further shaping and detailing.
These techniques are fundamental for any potter looking to create well-formed pieces. As you practice, you’ll get better at controlling the thickness of the walls and achieving the shapes you envision. Remember, patience and practice are key. Happy throwing!
Fundamentals of Pottery Making
Successful pottery relies on choosing the right clay, preparing it correctly, and mastering the technique of centering it on the pottery wheel. Proper methods and attention to detail are key elements in every step.
The Role of Clay in Pottery
The type of clay you use can profoundly impact your pottery experience. Earthenware, stoneware, and porcelain are the three primary types. Each type has unique properties and firing temperatures.
Earthenware is soft, easy to work with, and fires at low temperatures.
Stoneware is more durable and can be fired at higher temperatures.
Porcelain is very smooth and fires to a high, glass-like finish.
Understanding these differences is crucial to achieving the desired results in your projects.
Preparing Clay: Wedging and Kneading
Before you start, the clay must be well-prepared to eliminate air bubbles and achieve uniform consistency. Wedging and kneading the clay serve this purpose.
Wedging involves cutting and slamming the clay to remove air pockets.
Kneading is the process of folding and pressing the clay repeatedly. This aligns the clay particles and makes it easier to shape on the wheel. Remember, well-prepared clay reduces the risk of cracks and improves the overall quality of your pottery.
Centering Clay on the Pottery Wheel
Centering the clay on the wheel is one of the most critical skills you will learn. Begin with a firmly wedged piece of clay and place it in the center of the wheel.
Anchor your elbows on your knees for stability. Use both hands to press the clay into a symmetrical mound. Adjust your pressure evenly to keep the mound centered. Centering requires practice and patience, but it is necessary for creating balanced and symmetrical pieces.
Properly centered clay lays the foundation for successful pottery-making, allowing you to shape and pull the walls consistently.
Mastering the Opening and Pulling Techniques
Proper techniques in opening and pulling up walls are crucial for creating pottery on a wheel. Understanding hand positioning and consistency ensures better control and precision throughout the process.
Creating the Initial Hole
Start by centering the clay on the wheel. Use your thumbs to press into the center, forming a small depression. As the wheel spins, keep the pressure even and gradually widen the hole. This step sets up the foundation for the walls. Ensure the base is even to avoid weak spots.
Proper Hand Positioning for Pulling Up Walls
Correct hand placement is vital. Cup your hands around the clay with your thumbs inside and fingers outside. Apply gentle pressure with your thumbs while supporting the outside with your fingers. Slowly and steadily push upwards. This technique helps in achieving uniform walls.
Control and Precision in Pulling Walls
To maintain control and precision, keep your hands steady and movements consistent. Begin at the base and pull upwards evenly. Avoid sudden shifts in pressure, as this may cause the walls to become uneven. Wetting the clay often can also help in reducing friction. The goal is to smoothly pull the wall to the desired height and thickness.
Forming and Shaping Pottery Pieces
To craft beautiful pottery pieces, you need to master a few essential techniques. These include shaping bowls to create symmetry, collaring to refine the shape, and using tools to enhance details.
Shaping Bowls and Creating Symmetry
When shaping bowls, achieving symmetry is crucial. Start by centering the clay on the wheel to ensure balance. Use your hands to form the clay into the initial bowl shape, keeping the pressure even.
Gradually pull the walls up while maintaining a consistent thickness. Use the “C” shape with your hand to guide the clay upwards. Pay attention to the curve and depth, and make adjustments to ensure the bowl’s wall height and thickness stay uniform.
Collaring to Refine the Shape
Collaring helps you refine and narrow the shape of your pottery. Begin by moistening the rim of your piece to make the clay more pliable. Use your hands to gently compress the rim, bringing it inward. This technique is essential when crafting vases or bottles.
Applying even pressure is key. If one side of the collar becomes uneven, it can distort the entire piece. Maintain a steady pace, and re-moisten the rim as needed to keep the clay workable.
Using Tools to Enhance Details
Pottery tools can significantly enhance the details of your work. Tools like ribs, sponges, and wooden shapers help you achieve smoother surfaces and more precise shapes. For fine lines and textures, use carving tools or loop tools.
While shaping, use a rib tool to smooth out the surface inside and outside the piece. Employ a sponge to remove excess water and fine-tune the texture. Carving tools allow you to add intricate designs that elevate the piece from simple to sophisticated.
Using these techniques and tools transforms basic clay into stunning pottery with fine details and perfect symmetry.
Final Steps in Wheel Throwing
Completing a pottery piece on the wheel involves several essential steps including maintaining uniform wall thickness, carefully removing the pottery from the wheel, and properly drying, firing, and finishing the piece to achieve a unique and beautiful result.
Maintaining the Wall Thickness
Ensuring the walls of your pottery are of consistent thickness is critical. Use your fingertips to gently feel the thickness as you pull up the walls. Keep the speed of the wheel steady to prevent distortions.
For smaller pieces, fingertip pressure works well. For larger pieces, your knuckle may offer better stability. Always use an apron to keep yourself clean and focused on the task at hand.
Removing the Pottery from the Wheel
After shaping and pulling up the walls, you need to remove the piece from the wheel. First, slow down the speed to avoid damaging the soft clay. Use a wire tool to cleanly cut the base of your pottery.
Place a bat on the wheel head before you start working. This makes it easier to lift the piece without distorting its shape. Gently lift the bat off the wheel to move your pottery safely.
Drying, Firing, and Finishing
Once your piece is off the wheel, allow it to dry slowly to avoid cracks. Cover it lightly with plastic if necessary to control the drying speed. When it feels leather-hard, you can trim the base to fine-tune its shape.
Fire your piece in a kiln following appropriate firing schedules for your type of clay. After the initial bisque firing, glaze your pottery to make it both functional and beautiful. Fire it again for the glaze to mature and achieve the final finish.
