copper cookware numbers

melaina Nov 28, 2012 11:16 AM

Does anyone know what the numbers stamped on vintage copper cookware mean? I'm talking about ones such as "1," "3," and "5." I don't believe they have anything to do with size, because some of the pieces I have are the same size with different numbers. The numbers are typically stamped on the brass handles. Thanks.

    Hi, melaina:

    I've been collecting for awhile now, and I think the numbers on the handles and the rivets are part size or lot numbers, e.g., to signify the right internal radius for handle flanges (to match the pot's exterior radius), or for rivet dimensions. I don't believe the numbers have any significance once the pan is assembled.

      Thanks so much, kaleokahu. Shoot, I was hoping they added some kind of value. Thanks again.
