Identifying the Griswold Iron Mountain Line of Vintage Cast Iron Cookware

About the Griswold Iron Mountain Line

The Iron Mountain line of vintage cast iron cookware is one of my favorites from the old days. Sometimes, my Iron Mountain chicken pan is my absolute favorite, while at other times, I am really partial to my old cracked “ERIE” no. 11 skillet.

The catalog page shows the entire Iron Mountain product line from the Larry and Marg O’Neil collection.

According to the Blue Book, the Iron Mountain line was manufactured by the Griswold Manufacturing Company in Erie, PA in the 1940s. Neither the Griswold name nor trademark is on the pieces. 

I like this fine old cookware’s aesthetics, heft, and cooking surface. Because it is not marked with the Griswold name, it is also often found at a more reasonable price point than cookware marked with the Griswold trademark.

Because the line is “unmarked” – meaning it doesn’t carry the name or logo/trademark of the manufacturer – folks sometimes don’t know that their piece is part of the Iron Mountain line, made by Griswold. Here is some info to help you identify the Iron Mountain line.

What to look for to identify Griswold Iron Mountain

Skillet handle

The shape of the Iron Mountain skillet handle is unmistakeable – see above.

Heat rings

The Iron Mountain skillets all have inset heat rings. The heat ring, of course, is the circular raised ring at the bottom of the skillet. The ring’s purpose was to hold the pan within the open stove “eye” on the old coal or wood-burning stoves.

Pattern number

Every cast iron cookware piece in the Iron Mountain line is marked with a pattern number. The pattern number is typically found on the bottom or underside of the piece (as shown in the photos above). Each pattern number in the Iron Mountain line has four digits. The pattern numbers for the line are set forth below.

Iron Mountain Self-Basting Lids

Iron Mountain Covers are self-basting, with raised broken concentric circles on the underside, as shown in the photo above. Griswold also has self-basting lids, but their self-basting lids have raised unbroken concentric circles on the underside.

Iron Quality

The iron quality of the Iron Mountain line is that of Griswold. Once you’ve handled a number of Griswold pieces, you’ll get a feel for the iron. It is satin-smooth, lightweight compared to iron pans of current manufacture, and the walls of the pieces are much thinner than those currently made.

I think the Iron Mountain line is truly exceptional. If you find one at a reasonable price when you’re out hunting for iron, pick it up!
