Clay, like other natural materials, can change over time due to factors such as exposure to air, moisture, and contaminants. While clay itself doesn’t “go bad” in the same way perishable items do, it can undergo changes that affect its workability and performance.
If clay is not stored properly or is exposed to air for extended periods, it can dry out and become less pliable. Adding water and kneading the clay can help restore its moisture content and workability.
Clay can become contaminated with foreign materials or debris, which may affect its texture and quality. It’s important to keep clay covered and stored in a clean environment to prevent contamination.
Some commercially available clays may have expiration dates or recommended use-by periods. It’s advisable to check the packaging for any specific guidelines from the manufacturer.
While clay doesn’t spoil like food, it can experience changes that impact its characteristics. Proper storage, handling, and reconditioning techniques can help maintain the quality and usability of clay over time.
