Trying to figure out who made a particular pot or pan? Here are some starting points that might help you.

Field Guides

I have a growing set of posts about some of the more well-known European coppersmiths of the 19th and 20th century.


Field guide to DehillerinWhen you have a piece of copper in front of you, the first thing to look for are stamps — words, numbers, logos, or symbols that were pressed into the copper. Stamps can help identify not only the maker of a pot, but also the time period in which it was made.

Here are some of the different types of stamps you might find.

  • The maker of the piece
  • The store that sold it
  • Numbers for the size of the pan or to identify it (and its lid) in a busy kitchen
  • The name or initials of a former owner

My Stamps page has a more detailed explanation of this, and links to posts that list the ones I know.
