We often get asked how to repair handles when the metal part that is attached to the pan body starts separating or has completely come off. We aren’t aware of any services where you can send your cookware in to get repaired.
The surest way is to find a local welder that can either spot weld (typically how they were usually attached in the first place) or braze the pieces back together. Brazing is similar to soldering, where a metal filler is heated up such that it flows in the space between the two parts. I’ve seen one estimate for $35 for repairing a handle in this way, which is more than the typical Revere Ware vintage piece is worth. But for sentimental hand-me-down items, cost may not be an option.
I also investigated using an epoxy to repair a handle. By all indications, on a gas stove, the cookware can reach very high temperatures, perhaps as high as 500 or more degrees. JB Weld, a product well known for bonding metal together, does offer a high heat formula, but it is rated only up to 500 degrees. Another product is stainless steel putty, which is rated food grade and is often used to repair stainless steel food processing equipment. Unfortunately this is only rated to 250 degrees.
A third option is to drill small holes and use stainless steel hardware to reattach the handle. This is perhaps the most unsightly option.
I’d love to hear if anyone has tried this method or has had success repairing broken handles any other way.
