What is Slip in Pottery?

Slip is a mixture of clay and water that is used to decorate pottery. It is versatile and can be applied in various forms to achieve different textures and colors. Understanding the foundational elements of slip is essential for any potter looking to elevate their work.

Types of Slip

There are primarily two types of slips used in pottery:
