What is the purpose of slip in pottery making?

The purpose of slip in pottery making primarily serves the function of joining two pieces of clay together. Slip is a liquid mixture of clay and water that acts as a bonding agent, helping to ensure that different clay components adhere securely when they are pressed or joined. This is particularly important when assembling parts of a pottery piece, such as attaching a handle to a mug or combining different elements in sculptural forms.

In contrast, while slip can indeed be utilized for decorative finishes and to impart color to surfaces, its fundamental role centers on the structural integrity of the pottery-making process. Slip helps prevent cracks and ensures that joins remain secure during the drying and firing stages, which is essential for maintaining the final piece's durability and appearance. In summary, while slip has various applications in ceramics, its primary purpose lies in bonding clay components effectively.
