Seven ways to identify a cast iron skillet, six of them fully offline. Decode the number on the bottom, measure the rim, check for a recast, then see what it sells for.
Cast Iron ID is a decoding toolkit for antique American cast iron. The bottom of a skillet carries more information than a logo: a pattern number, a size number, a heat ring, a gate mark, the finish of the cooking surface. This app reads all of it, and only one of its seven tools needs a photo or a signal.
SEVEN WAYS TO IDENTIFY
- Decode a number. Type the number cast on the bottom and get the maker, the size and the typical diameter. 704 is a Griswold No. 8. 1058 is a Wagner Ware No. 8. 8SK is a Lodge. 35 pattern and catalog numbers, offline.
- Measure the pan. Enter the rim diameter in inches or centimeters and get the size number, with the tolerance collectors use. A pan that comes in an eighth of an inch small is flagged, because shrinkage is the classic sign of a recast.
- Date an unmarked pan. Tick the casting features you can see: heat ring, gate mark, raised or incised letters, machined or rough surface. The app intersects their date windows and tells you when two features cannot both be true.
- Read the markings. The offline path built for the middle of a flea market. Brand text narrows the maker, casting features and size number rank 88 logo variants, each with its own date window.
- Reproduction check. Ten recast tells weighted by how damning they are, plus maker-specific fake flags for Griswold, Wagner, Wapak and others. Get a plain verdict before you hand over cash.
- Restore or leave it. Enter the condition, get an honest answer: cook on it, cook with care, or display only, and what pitting, warp, heat damage or a crack does to value. Safe stripping and seasoning guidance, no shortcuts that ruin a pan.
- Scan the bottom. Point the camera at the pan and get a maker, a date range and a live market price range in seconds. Three scans free.
