What is the purpose of wedging in pottery?

Wedging is a crucial step in the pottery-making process primarily focused on kneading clay to ensure it is homogenous and free of air bubbles. This technique helps to prepare the clay for shaping and forming into various structures, whether for functional items like bowls and mugs or artistic pieces. By removing air bubbles, wedging minimizes the risk of those bubbles causing cracks or explosions during firing in the kiln, as trapped air can expand and create pressure.

Additionally, wedging allows for a more even distribution of moisture and consistency in texture throughout the clay, which contributes to the overall integrity of the pottery piece. The kneading process enhances the clay's workability, making it easier for potters to create, sculpt, and mold their designs effectively.

While adding decorative elements, drying the clay, or adding texture are important aspects of pottery, they do not specifically address the essential function of wedging, which is foundational for ensuring the clay's readiness for subsequent stages in the pottery-making process.
