Cast iron is incredibly durable. With proper care, it should last you a lifetime. But, mistakes happen in the kitchen. You might have dropped your pan accidentally. Or maybe you heated or cooled it too quickly.
Here’s how to repair your cracked cast iron skillet.
The simplest solution is to replace your cast iron pan. Check with the manufacturer to see if it’s under warranty. You might be able to get a new one for free.
If you want to keep your pan, you have two options. You can pay a welding company to weld the cast iron back together. Or you can try a product called Castaloy, a metal rod that melts at 500º to fill cracks in your cast iron cookware.
Keep in mind that it will likely cost more money to get the skillet repaired than to buy a new one. You also can’t guarantee how long the repair will last.
If you have experience working with metal, you can repair your cast iron skillet yourself. Effective techniques include welding, cold metal stitching, and brazing. Only qualified professionals should attempt any heat treatment processes. It’s vital to work with food-safe metals when repairing your cast iron pan.
The average homeowner can’t guarantee that the repair will be successful and extend the life of your cast iron. Not to mention that treating cast iron at high heat is quite dangerous.
