Cast Iron Cookware

The great American makers — their wares, their marks, and how to read the iron.

This is a citation-first reference to the foundries that made America’s cast-iron cookware, built one maker at a time. Every fact carries its source and a confidence flag: a primary document read directly, a claim corroborated across reliable collector authorities, or a figure still to transcribe from a page image. Where the record is thin, the page says so; where a popular story doesn’t survive scrutiny—a “counterfeiter” that wasn’t, a founding date that isn’t proven—it says that too. The recurring lesson runs under everything here: the name on a pan is often the seller, not the maker. Read the iron.

The makers — nine foundries, 1865 to today

Bars show each firm’s span (see each page for the precise cast-iron-cookware years and the founding-date nuances). Lodge is the lone survivor. Atlanta’s dashed bar marks the brand after its Atlanta foundry closed in 1957 — its later cookware was Birmingham-cast by BSR.

The “big three” — the premium marked makers

Griswold

Erie, Pennsylvania · 1865–1957

The benchmark — America’s most collected cast iron, and the one maker whose own catalogues priced every skillet to the cent.

Wagner

Sidney, Ohio · 1891–1957

Griswold’s great rival—and its 1957 acquirer. Its catalogue spec’d each piece to the eighth-inch but quoted the price only “on application.”

Spec’d, not priced · the inverse of Griswold →

Favorite

Piqua, Ohio · 1889–1935

The third of the big three, with the one joyful mark in cast iron—a smiling sun—and the Sears “Puritan” line it shared with Griswold.

The survivor

Lodge

South Pittsburg, Tennessee · 1896–present

The last major American maker, still going—and, for fifty years, so lightly marked that you date it by the notches in its heat ring.

Dated by notches, not logos →

The second tier — thinly documented, richly confused

Wapak

Wapakoneta, Ohio · 1903–1926

The “imitator” that wasn’t a forger. It cast off borrowed patterns—leaving faint ERIE ghosts—under its own Indian-Head mark.

Sidney Hollow Ware

Sidney, Ohio · 1886–1903

Four different “Sidneys” in one word. A cursive script is Philip Smith’s genuine ware; block letters are Wagner-made, from the same foundry.

Chicago Hardware Foundry

North Chicago, Illinois · 1900–1938

The diamond that isn’t Atlanta — a size number in a diamond, the mark collectors keep misreading. And Favorite’s pattern heir: it bought the Piqua patterns in 1934 and cast under the revived “Favorite” name.

The mass-market South — the Jones-family pair

Atlanta Stove Works

Atlanta, Georgia · 1889–1957

BSR’s Jones-family parent — and its opposite. Where the child signed nothing, ASW branded: a script mark, paper labels, and named lines (Small Fry, Lady Bess). But after 1957 an “Atlanta” pan was usually Birmingham iron.

Birmingham Stove & Range

Birmingham, Alabama · 1902–1989

The maker that signed nothing. Heavy, utilitarian, mass-produced Southern cast iron with no logo—you read the shape: its number system, an ever-present heat ring, and a distinctive angled handle.

Who really made this pan? — the threads that tie the makers together

The most useful skill in cast iron is telling a maker from a seller, and one maker’s iron from another’s. Six threads run across these pages:

The “ERIE” ghost. A faint ERIE can be a genuine Griswold—or a ghost on an early Wagner or a Wapak, cast from a pattern taken off a Griswold pan. The ghost isn’t proof of Griswold; the maker’s own mark is.
Two names, one iron. The Jones family owned both Atlanta Stove Works and BSR; from the 1920s they cast under both names, and after 1957 an “Atlanta Stove Works” pan was usually BSR (Birmingham) iron. The mark is the brand; the foundry is Birmingham.
The “Puritan” puzzle. Sears sold “Puritan” cast iron made by both Favorite and Griswold at once—told apart by the handle and Griswold’s 4-digit pattern number.
The diamond, and Favorite’s second life. A size number in a diamond is Chicago Hardware Foundry, not Atlanta—and CHF bought Favorite’s Piqua patterns in 1934, casting under the revived “Favorite” name. So a late “Favorite” pan may be Chicago iron, not Piqua.
The four “Sidneys.” The town, Sidney Hollow Ware (script), Wagner-made “Sidney” (block), and Wagner’s own “Sidney” kettle & “SIDNEY -O-” logo. Untangled here.
The store & budget brands. “Puritan” = Sears (Favorite/Griswold); “Wardway” = Montgomery Ward (Wagner); “Oneta” = Wapak’s budget line; “Miami” = Favorite’s. The brand names the counter, not the foundry.

How each maker treated a skillet in its catalogue

Maker	In its own catalogue, a skillet was …
Griswold	priced, by the “No.” — No. 8 = 50¢ (1888 & 1895, held flat).
Wagner	spec’d, by the “No.” + a catalogue number, size & weight — but “prices quoted on application.”
Lodge	priced, by the inch — an 8-inch skillet = 35¢ (c.1910).
Favorite	(no catalogue survives) — sold as premium Piqua Ware, budget Miami, and Sears Puritan.
Wapak	(no catalogue) — premium Wapak & budget Oneta, under the Indian-Head mark.
Sidney	(no catalogue) — script “Sidney O” = genuine; block = Wagner-made.
BSR	(no catalogue, no logo) — the mass-market maker; sold utilitarian & unmarked. Read the shape.
Atlanta	(no catalogue) — the Jones parent; branded lines (Early American, Small Fry, Lady Bess) + paper labels, but the iron is often BSR.
CHF	(only a furniture catalogue survives) — the diamond firm; sold Sani-Ware & the revived Favorite (Piqua patterns, Chicago iron).

One striking geography

Four of these nine makers grew up in Ohio. Wagner, Wapak, Sidney and Favorite grew up within a short drive of one another in the west-central part of the state—Sidney, Wapakoneta and Piqua are practically neighbors—and Favorite’s roots run to Cincinnati. The rest sit outside it: Griswold (Erie, PA), Lodge (South Pittsburg, TN), Chicago Hardware Foundry (North Chicago, IL), and the Jones-family pair — Atlanta Stove Works (Georgia) and Birmingham Stove & Range (Alabama). The pattern holds two ways: the premium marked trade was, to a remarkable degree, an Ohio story; the mass-market South was a Jones-family one. And fittingly, Favorite’s Ohio patterns lived on in Illinois — recast by CHF long after Piqua went dark.

Using & caring for cast iron — the general guides

Beyond the makers: what cast iron is, why it cooks the way it does, and how to keep it for a lifetime—seasoning, the soap question, and the myths worth retiring.
