Handbuilding methods and techniques
While handbuilding is as simple as using your hands to form an object out of clay, it encompasses three main techniques and forming methods. Once you have mastered pinching, coiling, and slab building, you can make just about anything out of clay.
Pinch pots are a great first handbuilding technique to learn when you first begin to work with clay. Simply begin with a single ball of clay and shape it into a small pot using only your hands by pressing your thumb into the center of the ball. Hold and spin the ball in one hand while you press the walls out with your thumb. Pinch pots are a direct method for beginning to work with clay and getting familiar with the medium.
Coiled pots are created by rolling out long individual coils of clay and joining them together to create a larger piece. Coiled pots can take on any number of forms, and the size can range from small to large. You can also combine the pinch pot method with the coil pot technique by making a shallow dish with the pinch pot method to use as your coiled pots’ base. Continue to build up your piece and keep adding coils until you are satisfied with the form and size.
A slab pot is formed by joining flat slabs of clay together after they have been processed through a slab roller. Slab rollers, which are basically industrial-sized rolling pins, are a great tool that allows for quick and efficient production of clay slabs used.
First, place your clay on the cloth of your slab roller and spin the wheel to move your clay through. Then, use a pointed tool to trim the slab to your desired size. You may make paper templates to follow to map out your project and cut the slab accordingly. You can also use a slump mold to create uniform shapes for things like plates and bowls. In this case, you would roll out your slab and drape it over or inside your form. Finally, you will join the two slabs together using a process called “score and slip.” Scoring your clay is essentially scratching marks on the two sides that will be joined together. After scoring, you will brush slip on each side as if you are gluing the sides together.
What materials and tools do you need for handbuilding?
You only need a few materials and tools to get started handbuilding pottery. There are a few essential items, like clay and a kiln, along with many optional tools that can add texture and depth to your pieces.
For handbuilding, use earthenware clay that is strong and easy to shape. Store it in a plastic bag to keep it moist. It is easiest to work with premixed, wet clay. If you are a local to the Bay area, Clay People in Richmond is a great resource for commercially produced clay. You can also get clay online from a vendor like Laguna Clay Company.
Clay is often sold in large bags, weighing anywhere from five to 50 pounds. When you first start your project, use a wire cutter to cut off smaller pieces of clay from your larger piece. Make sure to keep your clay bag closed when you are not working with it, as it can quickly dry out.
A pin tool is a sharp instrument used to cut, pierce, and incise designs on the surface of clay, adding unique texture. Many ceramicists also use second-hand dental tools to create unique texture on the surface of their piece.
Scoring tools are necessary for joining slabs together when handbuilding. Before applying slip, you will score the pieces of clay that you want to join together, so that the slip penetrates the clay and bonds the two pieces.
Slab roller and canvas sheets
A slab roller is used to roll out slabs of clay to an even thickness for slab building. If you do not have access to a slab roller, a rolling pin and two canvas sheets will work fine with a little muscle.
You will place your clay on a banding wheel to easily rotate your clay and make it easier to work on your piece. This is especially helpful with larger coiled pieces and when creating uniform textures.
A brayer comes in handy for rolling out and smoothing the edges of your clay, especially for the lips of bowls and cups. You can also use a brayer to add texture to the clay’s surface by impressing objects between the clay and brayer. [Photo: lace texture from Ceramics I]
Cut templates out of heavy stock paper to act as patterns for projects. Templates make it easy to duplicate a project when handbuilding.
Rubber ribs are essential tools used to smooth out the surface of clay.
Fettling knives are used for easily cutting slabs of clay. These knives can also trim, carve, decorate, and more.
While working your clay, prevent it from drying out by misting it with a spray bottle filled with water to keep it moist.
A damp sponge moistens the surface of the clay and keeps the surface smooth.
A kiln is used to fire ceramic work. Depending on your project and clay type, a kiln can take about 8 hours to heat up to about 2000 degrees Fahrenheit, and an additional 12 hours to cool down. If you don’t have access to a kiln, many ceramic studios offer pay-to-fire services and will fire your pieces for you. You will need to know the cone level of the glaze you are using and confirm that the studio can fire your piece at the correct temperature.
The Crucible does not offer pay-to-fire services at this time, but students are welcome to use our studio’s kilns and glazes when working on their own projects during The Crucible’s Ceramics Labs. If you are interested in Bay area pay-to-fire services, check out Potters Studio in Berkeley and Merritt Ceramics in Oakland.
Handbuilding project ideas
Once you have a few simple handbuilding techniques under your belt, you can make your own functional tableware, vessels, sculptures, and more.
Pinch pot bowls
Pinch pots are a great project for beginners to handbuilding pottery. Perfecting this technique is a great way to start developing your ceramics skills and familiarity with clay. You can make a set of small pinch pots to hold salt and pepper at the dinner table, or slightly larger bowls to hold sauces and other garnishes.
Coiling is a great technique for creating larger-scale projects as the next step up from pinch pots. Planters are a popular project in our Large Ceramic Forms class. When you are planning out your design, keep in mind that it is easier to coil a narrow pot than a wide one, as wider pots tend to get off-center and are prone to collapse.
Coffee mug and pour over
Make mornings special with a unique, handbuilt coffee mug and pour over set! Using a slab roller and paper cut templates, you can easily use your handbuilding skills to make a matching mug and pour over. You can use your new mug for much more than coffee, and ceramic pour overs are a great alternative to plastic.
How to learn handbuilding
In The Crucible’s Ceramics Department, students make sculptural and functional forms in clay, covering traditional hand-building and surface treatment techniques. You can get started in introductory classes like Ceramics I to dive deep into handbuilding, or try a 3-Hour Taster to explore a new art form without the deeper commitment of a full course. After you have the foundations of handbuilding down, we offer a variety of advanced handbuilding classes. In Large Ceramic Forms, you can pinch and coil a large planter or sculpture. In our Raku classes, students utilize a unique firing technique where ceramic pieces are taken out of the kiln glowing hot and placed in an oxygen-reduced atmosphere, giving sparkling colors to your glazeware.
What is the best clay for handbuilding?
Earthenware clay is the best clay for handbuilding pottery because of its strength and plasticity. Other clays, like porcelain, are not recommended for beginning handbuilding because they are stiff and not as easy to form. You can also use grogged clay, which contains a high amount of alumina and silica, reducing the shrinkage and protecting your piece from cracking when firing. The grog also provides strength if you are building larger pieces.
What is handbuilding with clay?
Handbuilding with clay allows you to create ceramic forms without using a throwing wheel.
How do you prepare clay for handbuilding?
Before starting to build your project out of clay, you need to knead it, a process also known as wedging. Kneading clay makes it easier to work and maintains a consistent moisture. It also eliminates air bubbles that may have been trapped when the clay was mixed or recycled.
What are the three methods of handbuilding?
The three methods of handbuilding are pinching, coiling and slab building. Once you have experience with these three methods, you can make just about any object out of clay. It helps to start with pinching, and build upon the technique with coiling, before moving onto to slab construction.
Can you do handbuilding without a kiln?
Whether or not you can do handbuilding without a kiln depends on the type of clay you use. If you are working with a self-hardening clay, you can let it dry overnight instead of firing it. There are also kid-friendly polymer clays that you can bake in the oven. The downside of these types of clay is that uses of your ceramic piece will be limited. You will not be able to eat or drink out of this type of ceramic piece.
If you are handbuilding with earthenware clay, use a kiln to fire it. Ovens do not get hot enough to fire earthenware ceramics, and if you’re not careful, baking the clay can cause it to crack. Depending on your project and clay type, a kiln can take about 8 hours to heat up to about 2000 degrees Fahrenheit, and an additional 12 hours to cool down.
