Thatcher Glass Manufacturing Company

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

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!

      Thanks Wayne for the correction! I don’t know how I missed that, or how long I had the error posted……..I have fixed it today! Take care and best regards,
      David

  2. Cindy Moss says:

    I found an old brown soda/ beer bottle with mTc on the lower rim. Any idea of what it contained and possible age?

  3. Brandon S Bowling says:

    I recently purchased a milk bottle with T. M’F’G. CO 16 embossed on the bottom. The bottle is a pint and has a purple hue. It says P.M. Davidson Pasteurized Milk and REGISTERED on the front.
    I was curious if you knew what year this bottle was made and if you had an idea of what state it was produced. Also, do you have any information on which state this dairy was located?
    Thanks

  4. Gary Moseley says:

    I found a bottle with the “double lined T”. Has there been any more information found on this marking?

    • David says:

      Hi Gary,
      Not to my knowledge. Can you send a pic of the bottle and the mark to my email address, which is listed on the bottom right-hand corner of the page?
      Thank you,
      David

    Thatcher Glass was one of the largest employers – about 800 – on San Fernando Rd. in Santa Clarita [northern Los Angeles County] when they closed – supposedly sold to a plant that made plastic bottles rather than glass bottles.

    • Matt says:

      Hi Bob, Were you connected with the Saugus plant? I have at least one relative who worked at the plant.

      Matt W.

      • Bob says:

        No – we lived there [1974-95] – less than one mile from the plant. Their sale and eventual closure was devastating to the local economy. Eventually Six Flags and the Valencia Town Center created more jobs but at a lower salary rate. The only other large employer [other than schools] was Newhall Refining. Little by little small manufacturers and auto repair shops moved into parts of the old factory buildings. I didn’t realize that the original buyer filed for bankruptcy soon after the purchase.

    I worked at Thatcher in Tampa,fl. It was my first job when i graduated high school. I worked on the hot end. I liked my job, but was most interested in the lab, I was very curious how glass was made. I remember when the plant closed. A lot of the older men talked about a TMC in Cuba before the revolution…is this true? Very fond memories of my first job after high school… thank you.

    • David says:

      Hi Aaron,
      Thanks for your post! I don’t know anything about a Thatcher glass plant in Cuba, but perhaps a reader with more information will let us know.
      Take care, David

    My whole Family worked for Thatchers at some point. First in Streator, then in Saugus. My grandparents retired from there, both with 38 years.

  8. BILL says:

    DEAR DAVID I HAVE A MILK BOTTLE THAT HAS ON IT REGISTERED SEALED 1-11-14 AND IT ALSO HAS BIG T OVER LITTLE MC WHICH ON THE WEB SITE SAYS C.1923 CAN YOU COMMENT ON THAT? PLEASE THANKS BILL.

  9. Shannon kelley says:

    Thanks David for your reply. I have so many I may be back in touch. I wish there was a site to go to I could plug in numbers and get a response. But your website has been very useful

  10. Shannon says:

    Thank you David for a fantastic informational page. I have been collecting sea glass on Marylands eastern shore and and have found quite a few glass bottoms which I am struggling with identifying. Right now I am trying to identify what I believe to be a Thatcher Glass bottom but cannot locate a rectangular brown glass bottom that saya “MADE IN USA” 855 mTf “logo” D126 5 8 53. Any help would be appreciated. I have many more to identify.

    • David says:

      Hi Shannon, the bottom is certainly from a bottle made by Thatcher Glass. What appears to be an “F” in the mTc logo is actually supposed to be a “C” although often it has an odd angular look. The “D126” is a distiller code so we can be sure it was from a liquor bottle (flask). Not positive about the other numbers but I assume the “53” is a year date code for 1953. “855” may be a style number assigned to that bottle. Hope this helps!

  11. Edward Flugel says:

    Above you have Lockport, NY as a bottle plant. I believe it should be Brockport, NY.

    • Edward Flugel says:

      Brockport, NY also, rather than wrong city.

      • David says:

        Hi Edward,
        Thatcher Glass Manufacturing Company acquired the Lockport Glass Company of Lockport, New York in August of 1919. That’s why the Lockport, NY location is included in the list of glass plants that were acquired, controlled or owned by Thatcher at some time during it’s history.
        HOWEVER, the Brockport, NY glass bottle container plant, which I believe you are referring to, is an Owens-Illinois (Owens-Brockway) plant, not a Thatcher Glass plant. Those are two separate glass companies. Take care, David
