if you are using recycled clay, wedge the clay on a solid surface, use your cutter, and cut in half, if you see any wavy lines in it, it needs more wedging. if you are using new clay you should not have to wedge but use it, making sure as when you are building that you do not leave air pockets in the piece work, otherwise it can explode in the kiln, worst case scenario
To make a clay pot, you need skills in hand-building techniques, such as pinch, coil, or slab methods. Understanding the properties of clay and how to properly wedge it to remove air bubbles is essential. Additionally, proficiency in using a pottery wheel can enhance your ability to shape the pot. Finally, knowledge of glazing and firing processes is important for finishing the piece.
