strawclay

Strawclay is a type of clay body used in pottery and ceramics. It is made by mixing straw with clay, typically in a ratio of about 1:10 to 1:20. The straw acts as a fuel during firing, providing a reducing atmosphere that can help to reduce iron oxides in the clay, resulting in a darker color in the final piece. This process is known as straw firing.

Strawclay is known for its ability to produce a wide range of colors and textures. The straw can be left in the clay, resulting in a textured surface, or it can be removed before firing, resulting in a smoother surface. The color of the final piece can vary depending on the type of clay and the firing conditions.

Strawclay is often used for functional ware, such as bowls and plates, as well as for decorative pieces. It is a popular choice among potters and ceramicists due to its versatility and the unique aesthetic it can produce. However, it requires careful handling and firing to avoid issues such as cracking or warping.

Strawclay is not suitable for all types of clay or firing conditions. It is typically used with kaolin or ball clay, and it requires a reducing atmosphere to achieve the desired results. It is also important to ensure that the straw is completely dry before mixing it with the clay to avoid issues during firing.
