How To Fix Your Cracked Cast Iron

Help! My favorite skillet has developed a crack. Can it be fixed?

—Jeremy B., South Carolina

THE SOLUTION:

A cracked skillet can still be used for what Jeff Rogers calls “light-duty” cooking, such as making cornbread. But if it’s a family heirloom, handed down through the generations, we recommend that you retire it from active duty, hang it on the wall, and show it off as a family heirloom. Even with light use, you never know when a faint crack will be enough to break a piece in two.

  1. I have had some luck by drilling a hole at the end of the crack, sawing along the crack with a saber saw with a hacksaw blade until you reach the hole, then filling the hole and sawed out crack with J-B Weld which is good to 400 degrees. Then sand the dried excess J-B Weld.

    • Is it food safe with the B.J. Weld? And they have so many products, which specifically did you use? I have a giant cast iron caldren tat has split down one side, and was thinking about when SHTF. As is it’s barely a flower pot!!

  2. If you are a welder or know one, it can be repaired. I have had good luck with cleaning the crack up real well and grinding in a bevel. Then using a nickel rod after the skillet is preheated to weld it up. Can’t even tell it was cracked after the weld, cleanup and reseasoning. Hope it helps.

  3. Doesn’t nickel have carcinogens? Isn’t it dangerous use nickel for cooking?
    I really don’t know the science of metals and irons, but I have heard in it a poison. I really don’t like the idea of making someone sick or dying.

  4. Have an old cauldron that has a cancered area in the bottom can i use j-b weld to fill it in and still use it?
