The Art of Coil Building
Updated: Sep 16
Coil building is a handbuilding pottery technique in which long ropes of clay, called coils, are stacked and joined to create vessels and sculptural forms. It is one of the oldest and most enduring ways of working with clay, used by cultures around the world for thousands of years, long before the invention of the potter’s wheel.
Ancient artisans rolled coils by hand and carefully layered them to form beautifully intricate shapes. These pieces served everyday needs, carried cultural meaning, and reflected the artistic traditions of their communities. Today, coil building continues that legacy, connecting modern makers with one of the most fundamental methods of working with clay.
What Is Coil Building in Pottery?
Coil building is a handbuilding technique in which clay is rolled into long ropes, or coils, and gradually stacked to create form. Each coil is attached to the previous layer and blended together to build walls and structure.
Unlike wheel throwing, coil building does not rely on rotation or symmetry created by a spinning wheel. Instead, the form grows slowly as each coil is added, allowing for greater control over shape, thickness, and design.
Potters often smooth the coils together to create seamless surfaces, but sometimes the coils are left visible as part of the final aesthetic. This flexibility makes coil building both a structural technique and a powerful design tool.

Why Coil Building Is Still Popular Today
Despite its ancient origins, coil building remains central to contemporary ceramics. Many artists choose this technique because it offers freedom that other methods cannot.
Working with coils allows potters to:
Create large or sculptural forms that would be difficult to throw on the wheel
Adjust shapes gradually as the piece grows
Build organic or asymmetrical designs
Focus on texture, carving, and surface decoration
Because the process unfolds slowly, coil building also encourages a thoughtful, meditative approach to making. Each layer requires patience and attention, allowing artists to respond to the form as it develops.
From Ancient Technique to Modern Design
While the technique itself is ancient, coil building is widely used in modern ceramics. Contemporary artists often combine coils with other handbuilding methods—such as slabs or pinching—to create complex forms.
Some artists highlight the rhythm of the coils as a visual element, while others smooth the surface completely to emphasize the finished shape. The technique adapts easily to both functional pottery and sculptural work.
From expressive vessels to architectural forms, coil building continues to inspire new approaches to clay.
Learning to Build with Coils
For beginners, coil building offers an accessible way to start working with clay. The technique does not require specialized equipment, and it helps students develop a strong understanding of form, balance, and wall thickness.
As coils are added, they must be joined securely so the walls become one continuous structure. Depending on the project and the moisture of the clay, potters may blend the coils together, compress the joins, or use scoring and slip to help strengthen the connection between layers.
As skills grow, potters can experiment with scale, texture, carving, and more ambitious designs. Each project builds confidence and deepens an understanding of how clay behaves.
Because the form grows layer by layer, coil building naturally encourages observation, patience, and careful craftsmanship.
Sculpting with Coils at Throw Clay LA
At Throw Clay LA, students explore coil building through guided projects and individual experimentation in our handbuilding courses. Students learn the fundamentals of building strong forms while developing their own creative ideas. You’ll learn how to:
Roll consistent coils
Join and strengthen layers
Shape balanced vessels and sculptural forms
Refine surfaces and explore texture
Continue the Tradition
Coil building has endured for thousands of years because of its versatility. The same fundamental technique can be used to build a small functional vessel, a large sculptural form, or something entirely unexpected. The tools are simple, but the possibilities for form, scale and surface are remarkably broad.
