What is the process of wedging in clay preparation?

The process of wedging in clay preparation is essential for ensuring the clay is workable and free of imperfections. Kneading the clay removes air bubbles that could cause defects during firing. Air pockets can expand and cause the clay to crack or explode due to the trapped air heating up in the kiln. Wedging also helps to evenly distribute the moisture throughout the clay, making it homogeneous, which is crucial for achieving consistent results in both shaping and firing. This thorough kneading creates a more pliable and malleable material that is ready to be shaped into various forms. The other processes described, such as molding, drying, and pushing through a mold, do not serve the primary purpose of preparing the clay by eliminating air bubbles and ensuring an even texture.
