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, New York; 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 was used from c. 1944 to about 1982. On this variation, the mark is often indistinct and the 2 smaller letters may be illegible. This mark is seen on a wide variety of bottles including liquor flasks and other containers.
T (double-lined letter, shown) , this was the last mark used by Thatcher, and dates from approximately 1981 to 1985. (Please see the email I received from Bill F, and which I quote from below). This mark has been confirmed on the base of an emerald green liquor flask with a 1985 date code, and an amber beer bottle with a 1983 date (pictured).
For some period of time, I was not sure if this mark was that of Thatcher, and noted that it MIGHT have been used by them, not being 100% certain. However, the mystery has now been solved once and for all…………… Here is a portion of a very informative email I received on May 8, 2018 from a former employee of Thatcher. He writes:
“I worked for Thatcher as a QC/Customer Service rep upon graduating from college in 1984 until Thatcher went out of business in 1985. I believe I was the last salaried employee hired. Although I worked from the Production and Engineering facility in Horseheads, NY, I spent a great deal of time in the Elmira NY, Wharton, NJ and Lawrenceburg, Indiana manufacturing plants.
“I can confirm that the double lined “T” was used on all containers manufactured by Thatcher in 1984. It was my understanding that the T logo was used on all new molds manufactured after the company was purchased by Dominic & Dominic from Dart-Kraft Industries in 1981. ” (Bill F, Elmira, NY)
In a subsequent email, he also stated that there might have been a gradual transition over a period of time after 1981 before the “new” mark was used on all molds, but he was quite certain that by 1984 all bottle molds in use did carry the “Double lined T”.
