p>Cracking in clay can occur due to various factors, including moisture content, firing temperature, and techniques used. While no clay is entirely immune to cracking, certain types of clay are less prone to cracking than others.
Clay bodies that are formulated for high-temperature firing, such as stoneware and porcelain, tend to have lower rates of cracking. The higher firing temperatures result in stronger and more durable ceramics.
Preventing cracking involves using proper techniques, such as wedging the clay to eliminate air pockets, allowing the clay to dry evenly, and using appropriate firing schedules to reduce stress on the clay during cooling.
While no clay is completely crack-proof, using high-fire clay and implementing proper techniques during the forming, drying, and firing processes can significantly reduce the likelihood of cracking in your ceramic creations.
