Yes, putting a hot pan, especially a cast iron skillet, into cold water can cause it to crack. This phenomenon is known as thermal shock. When a hot pan is suddenly exposed to a drastic temperature change, the material undergoes rapid expansion or contraction, which can lead to stress and ultimately cause the pan to crack or warp.
This risk is more pronounced with cast iron skillets because they have high heat retention and are generally thicker and denser than other types of pans. Nonstick pans, on the other hand, are typically made from materials like aluminum with a nonstick coating. While they are less likely to crack due to thermal shock compared to cast iron, they are still susceptible to damage.
To avoid thermal shock and prevent damage to any type of pan, including nonstick pans, follow these precautions:
Allow the pan to cool naturally: After cooking, let the pan cool down at room temperature before exposing it to water or any temperature changes.
Gradual temperature changes: If you need to clean a hot pan, let it cool for a few minutes, and then rinse it with warm water. Gradually increasing or decreasing the temperature differential helps reduce the risk of thermal shock.
Avoid drastic temperature changes: Never place a hot pan directly under cold running water or in a sink filled with cold water. Instead, let it cool down gradually on its own.
Check the manufacturer's instructions: Different types of nonstick coatings may have varying temperature limits, so it's essential to follow the manufacturer's guidelines on safe use and care.
By taking these precautions, you can help prolong the life of your cookware and minimize the risk of cracking or warping due to thermal shock, whether it's a cast iron skillet or a nonstick pan.
