Formerly headquartered at Toledo, OH; now based at Perrysburg, OH, Owens-Illinois, Inc. had (and has)  many glass manufacturing locations worldwide. (See list of 19 currently operating glass container plants in North America, farther down on this page).

Owens-Illinois Glass Company was the result of the 1929 merger between two glass-making giants of the industry: Owens Bottle Company (Toledo, OH; predecessor Toledo Glass Company began operation in 1896) and Illinois Glass Company (based in Alton, Illinois, glass production dating from 1873).

Shown on this page are pictures of typical trademark variations used on their containers, especially during the early years.  Most of the pics show the first and most widely recognized mark used beginning in 1929.  As pictured, it can vary slightly from one container to another.  It consists of a “Diamond and O (oval)  entwined, with an I in center” and dates from circa 1929 into the mid and late 1950s. (Latest confirmed date code with this older trademark known on a bottle is 1966).   The diamond/oval/i mark may not have been, in actual practice, implemented onto bottle molds until some time in 1930, simply because of the time and effort involved in re-tooling/altering molds already in use.

On very small bottles, the mark may be rather indistinct and the “I” may be virtually invisible, or just a tiny dot.  It may be misinterpreted as the number “1”.  On the typical bottle, there is usually a number to the left of, to the right of, and below, the trademark.
(Note: The above arrangement is the most commonly seen, at least on soda bottles, but some containers, such as liquor flasks, are frequently marked in other ways and thus the codes may be arranged in a different configuration).

Typically, the number on the LEFT of the diamond logo is the plant code number, the number on the RIGHT is a year date code, and the number below the logo (if present) indicates the mold number (mold identifying number, “mold cavity number” or serial number).  Examples: plant code #2 stood for the Huntington, WV plant; “3″ was the Fairmont, WV plant(number used up to 1981, later “3” was used by Muskogee, OK); “4” was Clarksburg, WV;  “7″ indicated Alton, IL; “9″, the Streator, IL factory; “12″ was Gas City, IN; “14″ was the Bridgeton, NJ plant, #21 is Portland, OR; #22 is Tracy, CA; #20 is Oakland, CA; #23 is Los Angeles, CA, etc.

Note: Several of the plant numbers used by O-I have been re-used by other plants opened in later years, so it is important to take into consideration the date code, the bottle style and other characteristics to positively identify which plant location made a particular bottle.

DATE CODES

On many bottles, a single-digit date code along with the diamond/oval/I mark may indicate the 1930s. From information compiled in Bill Lockhart’s article (link below) on Owens-Illinois’ date code markings, it appears that, on containers with this earliest trademark, if a single digit date code (such as “O” or “1” placed to the right of the logo) is followed by a period, the chances are very strong that the bottle in question dates from the 1940s, especially the 1940-1947 period. However, there are some exceptions to this general rule, and single-digit date codes were also used in later decades along with the later “I inside an O” mark (but without a period placed to the right of the code).
Most bottles from the late 1940s into the 1950s and 1960s have two-digit date codes. For more info, please check out this article by Bill Lockhart:
http://www.sha.org/bottle/pdffiles/owensill_blockhart.pdf

The second mark was phased in during the 1950s with the removal of the diamond. There was a gradual changeover from the “old” to the “new” trademark on containers which occurred over a period of four or five years beginning in 1954 (with a few known exceptions—see note below discussing a bottle made in 1966 with the “old” trademark).

Some bottle molds already in use were not re-engraved until as late as 1957, 1958, 1959, even, as mentioned, in 1966.  However, after c.1958 the great majority of O-I bottles carried the “new” (second) principal trademark, which merely consists of an I inside an oval, or circle.

OWENS” appears on the base of some clear prescription bottles.  Illustrated among the pics on this page is the base of a bottle made at the Columbus, Ohio facility (plant #18) with a date code of “7” which stands for either 1937 or 1947.

NOTE: Recently [July 2013] I have received a photo, submitted by Taylor McBurney,  showing the base of a Yacht Club Beverages ACL soda bottle, carrying a 1966 date code, but bearing the old logo! This is the very latest instance of use of the “old” O-I mark that I am aware of.  Presumably, when this particular mold was pulled out of the storeroom, and used to produce some more bottles (probably for a relatively small order), it wasn’t considered important enough to take the time to re-engrave the trademark.

The mark “O-I” has also been in use for some time in very recent years (but I’m not sure when it first appeared on containers).  The “O-I” mark shown on this page is on the heel of an emerald green ALE81 soda bottle made in 2011.

Other marks include “ILLINOIS” a brand name apparently used for a line of prescription bottles (similar to their bottles marked “OWENS”);   “DURAGLAS“,  a trademark used after 1940 and which appears embossed on innumerable bottles of many types;  and “LOWEX” another brand name which was used for their borosilicate glass forumula employed especially for power line insulators.

Although Owens-Illinois has made containers of many different shades of color over the years, the great majority of glass bottles commonly found (especially older containers that show up often at flea markets, antique malls, yard sales, junk shops, ebay, etc) are made of clear (colorless), green (emerald, forest green or “seven up” green) and amber (“beer bottle brown”) glass.

The diamond/oval/I mark is by far the most common identification mark on glass containers found in trash dump sites in the United States from the 1930s, 1940s, and 1950s. (The second most common mark encountered is probably that of the  Hazel-Atlas Glass Company.)

Electrical Insulators

Owens-Illinois took over operation of the Hemingray Glass Company factory, located in Muncie, Indiana, in 1933. Hemingray was a prolific maker of electrical insulators (of many types and sizes) for power lines, telegraph, telephone and other uses.  Within a year or two, most glass insulators produced at Muncie were carrying date codes. Owens-Illinois continued to have the great majority of insulators marked with the “HEMINGRAY” brand name, with very few exceptions in later years.   Other brand names used by O-I  on insulators include “Lowex” and “Kimble“.  Many millions of insulators were made at Muncie,  up to 1967.  (See my webpage on Hemingray Glass Company for more information on Hemingray insulators.)

    I have a old bottle the has the imprint on the bottom F.G on top half of Bottom and 7 on the lower half of Bottom. What would the history be of this bottle. There is no label.

  2. Randy Bishop says:

    I have a duraglas players 10 oz. soda bottle with different sports players on the front of it, on the bottom of the bottle it has #3 for the plant code, #48 for the date code,#1 for the mold code. Does anyone know what its worth? Or where can I find a picture of it at? Or any other information about it?

  3. Bill says:

    We have a duraglas from the Alton plant #7 on the left, the number 6 on the right (36 or 46?) and the mold #3 below. This is a Russian Soldier Vodka 1/2 Quart bottle, painted and molded, it pretty much looks like Stalin, big black mustache and with a bottle neck coming out of the top of his head. But we can’t seem to find this anywhere. Any contact with this bottle before? Or would there be anyplace to find info on the mold?
    Thanks,
    Bill

    • David says:

      Bill, I’m not familiar with the bottle, but Owens-Illinois has made tens of thousands of different bottles over the years. Perhaps a reader will have more info.
      Best regards, David

  4. Earnel Rayno says:

    i have a bottle with diamond/O and I logo. the left no.is 7 and the right side no.is 6. the logo no.below is 5 and the top of the logo no. is 5250 it is a giant bottle 20 inches tall…..

    • David says:

      Hi Earnel,
      Sounds like it may be a 5-gallon water bottle. If so, the markings show it was made in Alton, Illinois by Owens-Illinois Glass Company. The “6” on the right is probably a date code for 1936 or 1946. The “5250” is, I believe, a code number for that bottle type.

      ~David

  5. Jim curley says:

    I just dug my first bottle and would love to know more about it. It is 4″ tall x 2″ wide. Screw top (don’t have the lid) , says duraglas on the front, Owens on the bottom with a logo that looks like a sideways diamond with a circle going through it. There is a 6 to the left of the logo and an 7 to the right. Any ideas? Age? Value? What was originally in this bottle?

    • David says:

      Here are some points to help with age, etc:
      1) Duraglas is the trademarked brand name of Owens-Illinois Glass Company’s typical container glass, introduced in 1940.
      2) The number to the left of the Diamond/Oval logo is usually (but not always) the plant code number. “6” was the plant code for their Charleston, WV plant.
      3) “7” (date code usually on right) would stand for either 1947 or 1957. Probably 1947.
      4) Without seeing it, I can’t be sure of purpose, but most of these small screw-type clear bottles made by Owens-Illinois in the 1930s, ’40s, and ’50s are quite common, and so have little market value to collectors. Still, a nice little piece of mid-20th-century Americana! (Send me a pic of the bottle to email address listed at lower right on any webpage on this site).

  6. isabel saques says:

    I found a brown bottle bottom on Ocean Beach in San Francisco. It has half the Duraglas trademark in the center. I am trying to find out the range in years of the glass I found. The Duraglas trademark began in 1940. Is it still being used on bottles? If not when did it stop?

    • David says:

      Isabel,
      I’m sure the info is out there somewhere, but I’m not sure offhand exactly when the Duraglas brand name was discontinued (not sure if it HAS been discontinued??). The information is probably available somewhere at the official U.S. Patent and Trademark Office website. (Try searching that site only if you have lots of free time and don’t mind being frustrated by long ‘wild goose chase’ searches. :-) I usually have trouble finding exactly what I’m searching for on that website).
      In any case, most of the bottles I see with the Duraglas marking seem to date from the 1940s, 1950s and 1960s.
      Best regards, David

  7. Lindsey says:

    David, I find this so interesting because I found this glass in Jefferson Barraks memorial park here in St. Louis while mushroom hunting. This bottle has the 3ii on the back near the neck indicating size but no side markers. The top is a screw top and it’s got like a indicresiant coat on it and it’s clear

    • David says:

      Lindsey, the “weird 3″ symbol stands for “ounce” so your bottle is a 2 oz. medicine bottle. The “iridescent” coating is a result of being buried for many years— over the years the moisture in the soil very slowly disintegrates a microscopically thin surface layer of glass (gradually leaching out some of the soda), creating the “look” which is sometimes called “sick glass”…. The appearance can range from just a faint whitish stain all the way to outrageously beautiful multicolor “rainbow” effects on bottles that have been buried for a very long time. I think that the type of soil (mineral content) can also play a part in how colorful the effect may be. Thanks for your posts! ~David

  8. Lindsey says:

    Hi David I have a small medicine bottle marked 15 with a dot above the 5, oval diamond, 3. I can’t figure it out can you please help?

    • David says:

      Hi Lindsey,
      I’m not sure but I think the chances are good that your bottle was made at the Owens-Illinois Glass Co. plant located at Okmulgee, Oklahoma, which was their “#15 plant” until around 1939. The “3” may be a date code for 1933. However I don’t think there is any way to be 100% sure on that.

  9. Ken says:

    I understand your reluctance to make blanket statements. My source for this is an article by Bill Lockhart called “The Dating Game,” that appeared in the summer 2004 edition of Bottles and Extras. I have a .pdf file of the article that I’d be glad to share with you. As far as stippling goes, I just checked about a half-dozen of my 1940s 7 oz. bottles on the shelves (Squirt, 7up, Canada Dry, Bubble Up), and even the stippled bottles have clearly discernible periods.

    • David says:

      Hi Ken,
      Thanks for your comments —- good observations! I’m familiar with the article, and I am going to add another paragraph of text on this page, along with a link to that article. The base stippling, as you know, is less of a “problem” on larger bottles, but on some of the smaller bottles, it’s practically impossible to tell whether a period or dot (even though it may be slightly larger) is supposed to be there along with the single digit. However, we can just assume, with a pretty strong degree of confidence, that any Owens-Illinois bottle with a single digit date code number AND a period likely dates from the 1940s. Thanks!
      David

  10. Marie says:

    Your explanation of the markings on the bottom do not seem to relate to the jar I have. It is a large clear glass jar which I believe is a coffee jar. The numbers on either side of the oval /diamond are a 7 on each side – so when was this made?

    • David says:

      Hi Marie,
      Owens-Illinois has made thousands of different containers, and on many of them the markings do not always conform exactly to the most “typical” factory/date/mold code configuration. In any case, from your description, the number on the left (7), typically a plant location code, indicates production at the Alton, Illinois factory. The number on the right (7) is a date code, but since it is a ONE-DIGIT code, it is not possible to be 100% certain whether it stands for 1937 or 1947. (It is almost certainly one of those years.) There may or may not be a number (mold identifying number) situated directly underneath the logo. In your case I assume there is not. Hope this helps,
      David

      • Ken says:

        Bottles and jars with single-digit dates can be distinguished by whether or not there is a period after the date. If there is a period, then it was made in the 1940s. I have hundreds of Owens-Illinois soda bottles, and the ones I am certain were manufactured after 1940 (bottle design, graphics, etc.) almost always have a period after the date. It was O-I’s dating practice before it switched to double-digit coding. I have a Del Monte coffee jar with a 1. date code, which denotes 1941.

        • David says:

          Hello Ken, Thanks alot for your information. In general, I agree with you, and you are more than likely correct about O-I soda bottles…..but I hesitate to make any “blanket” statements on this site since I seem to find exceptions to nearly every “rule”. The practice of placing a dot after a single digit year code to indicate the 1940s may have been standard for most if not all soda bottles, but was this true on all of the other types? There are other problems including:
          1) Stippling (as you know, an overall pattern of tiny dots) on the base of many bottles makes it difficult, and sometimes impossible, to ascertain whether or not there is a specific ‘dot’ engraved after the single digit.
          2) I have a green 4 OZ jar marked with the “old” trademark and a single digit ‘1″ but with NO dot discernable, although there is a general stippling on the base. It also carries the Duraglas marking which indicates production after 1940. So this could theoretically be either 1941 or 1951. Since there is NO dot, presumably this is from 1951?
          3) I have a small emerald green vial, marked with a single digit date code (9) to the right of the “newer’ (second) trademark, just an I inside an O. This may stand for either 1959, 1969, or 1979. It certainly doesn’t date from the 1930s or 1940s.
          Thanks and take care!

    david I have a george dickle bottle that has the newer o i mark but still says federal law forbids and the date code is 1970 but i know that they ended this in 64 is this bottle uniuqe or why did this happen

    • David says:

      Hi Gerald, There are some bottles that continued to carry the “Federal Law Forbids” phrase on them, long after 1964. No one seems to know exactly why, but my “take” is that it simply wasn’t worth the time, effort and expense to retool (erase) markings engraved into the mold. It wasn’t of any “real” importance if the phrase was left on a bottle mold even after the phrase was no longer “officially” required. (Bottle molds were often used for a period of many years). Thus, some bottles made long after 1964 are seen with the phrase. David

  12. John says:

    Hello David, we found a small clear bottle with “N [IO] 81 N8″ printed in a single line at the base of the bottle. Since 81 was to the right of the new IO mark, we figured it stood for the year 1981, but is the N to the left of the IO the plant code?

    We found it half-buried in the woods on our land, and were just curious about what it might have once contained. Thanks!

    • David says:

      Hello John, Some relatively recent bottles made by Owens-Illinois do not conform to the “typical” marking system/configuration of earlier years. I believe the “81” is a date code for 1981, but I’m not sure what the “N” represents. It might be a plant location code. You can email a pic of the bottle to the email address listed at the lower right-hand corner of any page on this site. I am guessing it is a soda bottle.

  13. Kimberly says:

    I have a Duraglas water bottle with the lid. The numbers on the bottom are 7 (oval/diamond/ I ) 5. Can you please tell me an appropriate year for this bottle.

    • David says:

      Hi Kimberly,
      I can’t supply an absolute answer. The “5” stands for either 1945 or 1955. (My vote would be for 1945, but no guarantees). Since the brand “Duraglas” was not introduced until 1940, we can be sure it stands for sometime after that year. Also, it wouldn’t be 1965 since by that time the mark no longer carried the diamond. The “7” stands for their Alton, Illinois glass plant.
      Best regards, David

  15. eric says:

    Found a owens glass mason jar which has saturn symbol and left number is 23, right number 3. What year is this jar and do items like these ever have a value?

    • David says:

      Hi Eric,
      Owens-Illinois has made alot of generic “mason” or fruit jars. Some of them may have been “packer jars” (containing various foods, bought retail at the grocery store) and they were frequently saved to re-use as canning jars or containers for storage (nails, nuts, marbles, buttons, screws, etc) . Yours indicates manufacture at their Los Angeles, Ca facility (plant code #23); I believe that number was used circa 1948 to 2004. “3” probably stands for 1953. Value is subjective, but since these are common jars, typically 50 cents to a dollar or two value to jar collectors. Any damage will reduce the collector value to virtually nil. Of course it can still be used for “practical purposes” and if in decent condition (no cracks or chips) will always retain some utility value, regardless of “collectibility value”.

  16. Maureen says:

    My husband was uncovering a rock wall along our property and came across a Duraglass bottle. It’s green. It has a 3 on the left of the diamond over the oval emblem. There might be a little something inside the diamond. Very hard to tell. To the right of the emblem is the number 4 and then a smaller 7 slightly above the 4. Under the diamond/oval emblem is the number 18. Any idea what year this is??

  17. Nora says:

    Hello David,
    I found a gold decanter that has the OI on the right and D126 above 55 65 and 10 on the right. I’m wondering if this means its from Owens-Illinois Atlanta, Georgia in 1955-65? It also says “Federal Law Prohibits Sale Or Re-Use of This Bottle”.
    Thank you =)

    • David says:

      Hello Nora,
      These Owens-Illinois decanters and liquor bottles often have code numbers on the bottom that are arranged differently than the more common configuration as seen on most soda bottles. This has created confusion for researchers. I believe either the “55” or the “65” is a date code, but I don’t know which is correct. I think it is more likely the “55” (for 1955), but I really don’t know for sure. “10” may be a mold number. I understand that “10” was a factory code number for Atlanta, Georgia location, but that plant number was instituted around 1960. (The number “10” had also served as the factory code number for their Newark, Ohio glass plant earlier on, but that was in use circa 1929-1938). In conclusion, I cannot give you any information that I can guarantee is absolutely correct. (Perhaps a reader, or another researcher, has more information that can clear this up). Sorry about that,
      Best regards, David

    • David says:

      Krystal, the makers mark is “I inside an O”. Made in 1985 by Owens-Illinois Inc, emerald green non-returnable soda bottle, perhaps contained Sprite, 7-up, etc). Many of these types of soda bottles from the 1980s and ’90s have rather faint embossing arranged along the lower “heel” of the bottle.

    I found a Dad’s Root Beer 10-oz. bottle (“Big Junior” size) dated 1960. It was made in Alton, Ill, and it bears the diamond O-I trademark. It’s the first bottle from the 1960s I’ve found bearing the old trademark, and I’ve been collecting soda bottles since I was 15 years old (1978).

    • David says:

  20. casey says:

    what year is the date code 3?

    • David says:

      Casey, a single digit, such as “3” on the right side of the “old” Owens-Illinois logo (Diamond and oval superimposed, with I inside) can theoretically stand for several different years, including 1933, 1943 or 1953. If the “3” is accompanied by the “newer” mark (I inside an O) it could stand for 1963 or 1973. Sometimes a date code was reduced to only one digit on a very small bottle. However, that doesn’t always hold true. If your bottle carries the “old” logo, I think the chances are highest that it stands for 1933, but I can’t guarantee that. Perhaps 1943. Sometimes additional information about the bottle can narrow down the date range. For instance, if the bottle also carries the DURAGLAS brand, we can be sure it was made after 1940, the year Duraglas was introduced.

  21. Russell Kolb says:

    I purchased a Kolb’s Bavarian Type Brew beer bottle. The Kolb Brewery was in Bay City, Michigan and closed during or shortly after prohibition. Left of the diamond-I logo is a 3; to the right is a 6; below is a 2. Near the opposite edge of the bottle is a larger “G 11.” Can you tell me how old the bottle is?

    • David says:

      Hi Russell,
      The bottle likely dates from 1936 (the 6 on the right of the logo is a year date code). Assuming your information on the date of closing of the brewery is correct, it would not stand for 1946.

      Best regards,

  22. Valerie says:

    I found a bottle in a farmhouse basement that is green with the I O diamond mark. The center I barely has any length. To the right is a 2, the bottom seems to be stamped off center so cannot tell what was stamped to the left. Beneath it is an 8. Beneath that is PAT APPLD FOR. It is not stamped with Sunsweet nor Duraglas. It is not completely round as it has flat angles coming off of the flat bottom but then becomes rounded on top so is neither completely round nor completes a hexagon. The flat front and back of the bottle have a set of 3 raised arcs at the 3, 6, 9, and 12 positions. I have seen one similar bottle for sale in a group of green bottles on ebay but the person had no information. Appreciate any help you can give! Thanks!

    • David says:

      Valerie,
      Can you send me a clear pic of this bottle,and a closeup of the base mark, if possible. (My email address is at the bottom of the page). I tried emailing you directly, but the email you gave was invalid.
      Best regards, David

  23. Hi David. My husband & I found what looks to be an old pickle jar in the woods. It has the Diamond & Oval w/capital I marking on the bottom with a #7 to the left, #4 to the right & #4 below. I think the #4 to the right is the possible dates of 1934, 44, or 54 ; probably 54. I think the #7 is the factory in Alton, IL, & the #4 below is the mold #. Am I correct? The one thing I can’t find any information about is the number C2989 located next to the name Duraglas at the bottom of the jar. Would you have any idea what that would mean? I am wanting to restore the jar- lid & handle- for my parents but I am not positive what the jar was used for. Any ideas from you would really be appreciated.
    Best regards and God bless,
    Mary

      Hi Mary!
      You are correct, although I am thinking the “4′ most likely stands for 1944. Would you be able to email me a photo of this bottle? (Send to the email address listed at the very bottom of any page on this site). The “C2989″ would almost certainly be a code number for that particular bottle style (i.e. catalog number, inventory number, design number), used in communications between the glass factory and the company(ies) they sold the bottles to.

    where can I find information on Owens-Illinois whiskey bottle marks?

    • David says:

      Milt, I don’t know of any source for information that specifically discusses Owens-Illinois whiskey bottle marks. Good luck on your search for info.

    Thanks for your speedy reply!

    HI, I have a 10 in tall x 4 in wide Amber Glass Bottle, Diamond/ Oval and I inside marking on bottom. It has a 14 to the left, 3 to the right and 8 under the logo. What can you tell me about it?
    Thanks,
    Sharon

    • David says:

      Hi Sharon, the “14” is a factory location code number for Owens-Illinois Glass Company’s Bridgeton, New Jersey glass manufacturing plant, where the bottle was made. The “3” to the right is a date code which stands for either 1933, 1943, or 1953. Sorry but I don’t know which year it would be. The “8” is a mold number.

    Hello,I also found an old coca cola bottle with the diamond and oval with a capital I inside. It says Chicago, IL with an S on the bottom. Does this mean it was made in 1947? Can you give me any information so I may find the value of this bottle.

    • David says:

      I’m sorry, but I don’t do appraisals. I have no idea if your bottle was made in 1947, since you don’t mention any numbers on the bottle that might possibly be a date code.

      • Cheryl Secrest says:

        Sorry, I had the numbers in the first time I entered my comment which did not take so I had to rewrite. The numbers were 17 on the left of the logo and 47 on the right.

        • David says:

          Hi Cheryl,
          Your bottle was made at the Clarion, Pennsylvania glass plant (facility #17), and yes, the number “47” on the right side of the O-I logo would indicate 1947.
          Take care,
          David

    I found an old bottle with this logo but there is a 6 to the left of the logo, a 17 under the logo, and a 6 to the right. Does this mean it was made in 1906?

    • David says:

      Hi Lindsay,
      I am assuming by “logo” you mean the “diamond and oval with an I inside”. To begin with, Owens-Illinois did not come into being until 1929 (O-I was a merger of Illinois Glass Company, and Owens Bottle Company). So it is totally impossible for the “6” date code to stand for 1906. The “6” on the left is a plant code number that stands for the Charleston, West Virginia glass plant. That plant operated up to (I think) around 1962, give or take a year. The “6” on the right, which is the date code, could theoretically stand for either 1936, 1946 or possibly 1956. However, I am of the opinion that it stands for 1946. Note that this is just my opinion…….I don’t have proof of that. The “17” is a mold number. Thanks for writing!
      David
