How clay pot decay?

Clay pots can decay primarily due to environmental factors such as moisture, temperature fluctuations, and exposure to the elements. Over time, water can seep into the porous material, leading to cracking and structural weakening, especially when freezing temperatures cause the water to expand. Additionally, biological factors like mold and mildew can contribute to deterioration. Finally, physical impacts or abrasion can also lead to the gradual breakdown of the pot's integrity.
