Coiling Technique is a traditional technique for creating clay vessels. It involves rolling clay into long, rope-like strands, which are then layered and coiled to form a shape such as a vase, pot, or bowl. This method allows for the creation of large vessels without the use of a rolling pin, and is one of the basic techniques still taught in ceramic studios around the world today.
The coiling technique has been around for 4,000-5,000 years and is found in many ancient civilizations in Africa, Central America, China, and Japan. It is the simplest method humans could use to create clay containers without the need for complicated tools, and is considered the “beginning of pottery.”
The main steps in coil molding are not difficult. They include kneading the clay to soften it and removing air to prevent cracking when fired. Then, turn the clay into long, uniform strips, about the thickness of a little finger. Then, gradually build the base of the piece, using a flat piece of clay as a base or coiling the clay strips into a circle and smoothing them out. Then, layer upon layer of strips of clay. The lines can be adjusted inward or outward to control the shape of the container.
The most important point to be very careful about is connecting each layer. You must use slip to apply and smooth the joints to prevent separation. Finish by decorating and smoothing the surface. Or if you want to show the coiled grooves for a traditional beauty, you can do so.
For clay that is suitable for coil molding and is very popular. namely
-
Earthenware is an easy-to-shape clay, perfect for beginners.
-
Stoneware It is a soil that provides strength to the workpiece, making it suitable for work that requires durability.
-
Terracotta clay gives a reddish-orange color and is widely used in handicrafts and decorations.
The advantage of coil molding is that it does not require a turntable, it can easily produce large containers, it gives the work a unique look, it can show the coil grooves or keep them smooth, and it is a technique that can be used in both art and real containers.
