Thatcher Glass Manufacturing Company marks (c.1904-c. 1985)
Thatcher Manufacturing Company / Thatcher Glass Manufacturing Company has a long and very confusing history. During the earlier years, (1889-c.1904) this company sold dairy-related products including milk bottles that were actually made by other glass companies, especially Whitall Tatum and Company. The first plant where they actually made their own bottles was built at Kane, Pennsylvania, circa 1904.
Later glass plants were eventually built (or acquired through purchasing other glass companies) including locations at: Ottawa, Illinois; Streator, Illinois; Elmira, New York; Wharton, New Jersey; Mt. Vernon, Ohio: Lockport, New York; Dunkirk, Indiana; Clarksburg, West Virginia; Olean, New York; Winchester, Indiana; Cedar Grove, West Virginia; Parkersburg, West Virginia; Lawrenceburg, Indiana; Long Island, New York; Muscatine, Iowa; Saugus, California; Jeannette, Pennsylvania; and Tampa, Florida. Some of those plants operated for a relatively short period of time. (For more info on the individual plants, see the .pdf file on Thatcher, by Lockhart et al (link near the bottom of this page).
Thatcher Glass was acquired by Diamond-Bathurst in 1985. Diamond-Bathurst went into bankruptcy in 1987, and was later purchased by Anchor Glass Container Corporation, now part of the Ardagh Group.
Marks used by Thatcher include:
T.M’F’G.CO (mark used c. 1904-1920s)
T M C (c. 1910s-1920s)
T.MFG CO (c. 1910s-1920s)
M T C inside a triangle
M T C
This variation is seen in the form of a large T with smaller “m” and “c” sheltered underneath the “roof” of the T, in rather plain “block” style lettering (as shown in photo). This mark was used c.1923 into the early 1950s, and is usually seen embossed on the heel of clear glass milk bottles.
Thatcher Glass produced TREMENDOUS numbers of milk bottles that were used by MANY dairies, large and small, located across the United States. Many of these dairies had bottles made specifically for them with the dairy name and/or city and state embossed (i.e. with raised lettering) on the front. Some bottles made by Thatcher would also be classified as “generic”, with no markings other than the glass manufacturer’s mark on the heel or the base.
MTC variation: T, vaguely resembling an anchor with horizontal upper stroke, with smaller, angular M and C nestled underneath to the left and right. This particular mark used from circa 1944 to circa 1982(?) On this variation, the mark is often indistinct and the 2 smaller letters may be illegible. This mark was first used about 1944 and is seen on a wide variety of bottles including liquor flasks and other containers.
T (double-lined letter, shown) , I think this might have been used circa 1982 to c. 1985. This has been confirmed on the base of an American-made (I assume) emerald green liquor flask with a 1985 date code, and an amber beer bottle with a 1983 date (pictured). This may be the very last mark used by Thatcher Glass Manufacturing Company, although I don’t have positive confirmation on that attribution. I may be completely wrong here. I received a post from Lloyd McWilliams who wrote that this mark was never used by Thatcher. (See his letter from October 2014 in the “Comments” section on “Glass Bottle Marks Page 5”. In any case, I would certainly like to find out the correct identity of the user of this “Double-lined T” mark. If you have information concerning this mark, or have seen it on other bottles, please contact me!
