slipwashed

Slipwashing is a technique used in the production of ceramics, particularly in the creation of earthenware and stoneware. The process involves applying a slip, which is a suspension of clay particles in water, to the surface of a ceramic object. This slip is then washed off, leaving behind a thin, smooth, and often slightly glossy layer on the surface of the object. The purpose of slipwashing is to create a uniform, smooth surface that can enhance the aesthetic appeal of the ceramic piece and provide a protective layer against wear and tear.

The technique is typically used on the interior surfaces of ceramic vessels, such as bowls, plates, and mugs, to create a smooth, non-porous surface that is easy to clean. It can also be used on the exterior surfaces of ceramic objects to create a smooth, glossy finish. Slipwashing is often used in combination with other decorative techniques, such as glazing, to create a variety of surface effects.

The slip used in slipwashing is usually a body slip, which is a suspension of the same clay body that the object is made from. This ensures that the slip and the body are compatible and will not cause any issues with firing or warping. The slip is applied to the surface of the object using a brush or sponge, and then allowed to dry. The object is then fired in a kiln, which causes the slip to fuse with the surface of the object, creating a smooth, non-porous layer.

Slipwashing is a versatile technique that can be used to create a variety of surface effects in ceramics. It is a simple and effective way to create a smooth, protective surface on ceramic objects, and is widely used in the production of earthenware and stoneware.
