Owens-Illinois Glass Company
Bill Lockhart
A few years back, I was asked to conduct the analysis of a fairly large assemblage of amber bottle glass that was excavated by the University of Texas at El Paso. Most of the artifacts were fragmentary and consisted of amber beer bottle glass. This provided me the opportunity to observe a large sample of amber beer bottle bases from the 1933-1941 period. I noticed an interesting pattern in the Owens-Illinois bases that did not fit the description from Toulouse’s Bottle Makers and Their Marks. That set me on a quest to look at as many Owens-Illinois bottles as I could find (mostly beer, soda, and milk) to see if the pattern occurred regularly. What I discovered was a more refined way to date Owens-Illinois bottles from the 1940-1946 period with information provided by their marks. While I was looking, I discovered that Pepsi-Cola bottles made by Owens-Illinois followed a still different pattern in their markings as did those from Coca-Cola.History
The Owens-Illinois Glass Co. began with the merger of two of the industry’s giants: the Illinois Glass Co. and the Owens Glass Co. The Illinois Glass Co. was incorporated in March 1873 and began business in August. The company was successful and made virtually every type of bottle. By 1911, Illinois Glass had obtained the first of three Owens Automatic Bottle Machine licenses and made many other containers from semiautomatic machines. The firm expanded until the merger with Owens (see Lockhart et al. 2005a for a discussion of the company and its marks). The Owens Bottle Co. (1911-1929) grew from a series of companies that began with the Toledo Glass Co. (1896-1903). The Toledo company was succeeded by both the Owens Bottle Machine Co. (1903-1911) that made and sold the Owens Automatic Bottle Machine and the Northwestern Ohio Bottle Co. (1904-1908), a company that make bottles. In 1929, the firm merged with one of its major competitors, the Illinois Glass Co. to form the largest glass company in the industry. The merger between the Owens Glass Co. and the Illinois Glass Co. brought under the Owens umbrella the “largest individual bottle plant in the world” (Paquette 1994:71). The merger was formally approved on April 17, 1929 (Paquette 1994:70). On March 25, 1931, the firm was incorporated in California as the Owens-Illinois Glass Co., Ltd. The newly renamed organization purchased the Illinois Pacific Coast Co., the largest glass manufacturer on the West Coast on November 30 of the same year. The name of the West Coast operation was changed to the Owens-Illinois Pacific Coast Co. on April 23, 1932 (Paquette 1994:81-82). According to Paquette (1994:81) Owens-Illinois introduced Applied Color Lettering (ACL) in 1931, although other sources place the date of the practical application at 1934. Owens-Illinois purchased Brockway, Inc. in 1988, renaming the combined giant Owens-Brockway. According to Paquette (1994:45), the Owens scars appeared on the earliest bottles, made in 1904 and 1905 and continued until the final two machines, “AQ” models, were phased out of the Gas City, Indiana, plant on December 17, 1982.Types of Marks
There are at least three different types of marks embossed on returnable bottles by the manufacturer. These were probably not placed on the containers at the behest of the purchaser (the actual bottler) but reflect the needs of the glass house. The first type is the manufacturer’s mark. These are usually symbols and/or letters embossed on the heel or base of the bottle that identify the maker of the container. These were used at least as early as 1821 by Henry Ricketts on his now well-known style of mold that included what was probably the first plate mold (often called slug plates – although the industry term was “plates”) on the base of his bottles. Date codes are usually one- or two-digit numerals that indicate the year the bottle was made. This idea appears to have been conceived in conjunction with machinemade bottles. At this point, I have not seen date codes embossed on any blown-inmold bottles (with the possible exception of Hutchinson bottles made by the Illinois Glass Co. between 1901 and 1903). Date codes are often integral with manufacturer’s marks, embedded in mold codes, or they stand alone. They probably originated as tracking devices for returnable bottles. Manufacturers and bottlers alike wanted to know the number of round trips a bottle would make in typical use. Mold codes are cryptic marks embossed on the heels or bases of bottles. According to Miller and Jorgensen (1986), “bottle mould [a “u” in the word mold is correct in British and Canadian English] numbers serve several functions,” including the following:- Identification of the bottle, particularly for customers placing orders;
- Mould and inventory control of the factory;
- Quality control for bottle production, i.e. bottles with defects can be used to identify the defective moulds that produced them
- Production liability, e.g. should a bottle burst, the mould number, in combination with trademarks and date codes, can tell how old the bottle was and what company produced it.

The OI Mark
Owens-Illinois changed to a new variation of its manufacturer’s mark during the mid-1950s. The new mark was identical to the old one except that the elongated diamond was eliminated leaving only an I in an oval. The dating scheme, however, remained the same with the company code to the left of the mark and the date code to the right. Other combinations of letters and numbers often appeared on some part of the base, possibly identification numbers for the bottle style (catalog numbers), although they could have other meanings. The timing of the change is subject to a bit of controversy. According to Toulouse (1971:403), the older mark (with diamond) was used from 1929 to 1954, and the new mark (without the diamond) was used “since 1954.” Peterson (1968:49) agreed with a beginning date of 1954 for the new mark. Both almost certainly referred to the change that occurred in 1954. Although planning for the change had begun a year earlier, 1954 was the year that Owens-Illinois Glass Co. became Owens-Illinois, Inc. The conversion included a modification of the logo to the “‘I’ placed within a larger ‘O'” (or oval). It was not until shareholders voted at the company’s annual meeting on April 21, 1965, however, that the name was legally changed (Paquette 1994:147). As you will see below, the transition was not nearly as smooth as the official pronouncement would indicate. Using empirical methods, Giarde (1980:80), discovered that the “diamond and circle mark appears on milk bottles through 1956 with the new circle mark appearing on 1957 milk bottles.” Giarde’s ideas set me looking through my soda bottles, and I discovered the older diamond-oval-I marks with date codes up to 58 (1958) and David Whitten found one from 1959 (from factory #7)! Although currently unconfirmed, a date code of 60 (1960) in conjunction with the older mark has been reported. The newer, I-in-an-oval marks, however, began at least as early as 1956 (a 56 date code), so there was a minimum of a three-year overlap. If we could find enough bottles with both types of marks from 1954 through 1958, it would be interesting to see which factories changed at which times. It may be that some plants adopted the new system earlier than others. The Oval I mark continued in use after the 1988 name change to Owens-Brockway and is still used in 2005 (Powell 1990; Emhart 1996:49; 2005).Variations in the Owens-Illinois Code
Owens-Illinois was very inconsistent with its date codes. My “key” holds true most of the time, but neither it nor any other will be 100% accurate. The dot system was used on returnable bottles from 1940 to at least 1946. The earliest two-digit code I have heard of or seen was 43 (1943). Occasionally (especially on whiskey bottles), the code to the right of the logo does not make sense as a date code and should be ignored. Other times, the plant and date codes are placed somewhere else – not in conjunction with the logo. On many flasks, the factory and date codes are both to the left of the logo (separated by a dash) and are oriented perpendicular to the logo. More empirical and historical research needs to be undertaken on liquor-bottle codes, and Carol Serr is currently collecting such data. As a slight aside, Giarde (1980:77-94) devoted 17 pages to discussion about the Owens-Illinois Glass Co. Along with specifics about dating, he included a section on the lightweight milk bottles (invented by Julian Harrison Toulouse), tables about the dates on the lightweight bottles, discussions about each individual plant, and a section on coffee creamers. Giarde is by far the best reference for manufacturer’s marks on milk bottles. Owens-Illinois also used the older mark (with the diamond) in three slightly different variations. All three differences center around the I inside the diamond. The first is a simple vertical line (sans serif lettering). The second style has two horizontal bars, one attached to the top and one to the bottom of the “I” (serifs). The final style has the serifs but they are slightly upswept and attached to the oval (figure 2). At this point, I have not been able to find a specific connection between factories or time periods. These seem to have been used at the whim of the engraver rather than as identifying marks from factories. The newer mark appears in the first two styles but not the one with the serifs attached to the oval. In some cases, especially on smaller bottles, the “I” is reduced to a dot.Coca-Cola Bottles
An interesting exception to the usual markings is the date (and plant) codes on the bases of Coca-Cola and Pepsi-Cola bottles. The two major soft drink companies (Coke and Pepsi) have both required bottle makers to adhere to specific requirements in marking their respective bottles. For a good survey of manufacturer’s marks, date codes, and other information associated with Coke bottles, see the Coke Bottle Checklist (1996) by Bill Porter. Porter discussed where date codes and other marks are found and what to look for. Lockhart (2000; 2003:34-37) consolidated known data on dating the characteristics of Coca-Cola bottles. Before making a connection with Owens- Illinois, a few generalizations about manufacturer’s marks on Coca-Cola bottles need to be examined. The earliest variation of the almost universally known “hobbleskirt” bottle is marked PAT’D November 16, 1915. Many of these have no manufacturer’s marks. When such marks are present, they are usually on the heel of the bottle. Until 1934, the bottles made by Owens- Illinois maintained the standard Owens- Illinois marking system (e.g. 9 OI mark 3) located on the heel. Virtually all glass houses making Coke bottles had changed to “skirt” markings by 1934 (see below). This consists of a two-digit mold code followed by a manufacturer’s mark (in the case of Owens-Illinois, the earliest mark with the elongated diamond) and the twodigit date code (to the right) all embossed on the narrowest constriction of the “skirt” or lower half of the bottle. In 1951, two changes occurred simultaneously. The date code migrated to the left, and the manufacturer’s mark moved to the base of the bottle. The remaining embossing on the skirt was the two-digit date code, a dash (-), then the two-digit mold code on the right. These changes occurred about mid-year, so Coke bottles are found with both configurations. Some Owens-Illinois-made Coke bottles actually used the standard Owens- Illinois format (e.g., 24 OI mark 4 – Porter 1996:4, 7). The Owens-Illinois mark on Coke bottles changed to the Oval-I mark about 1954 (when it changed on other bottles – see above). The final mark-related change on Coke bottles occurred by at least 1953 (probably in 1951), when Owens-Illinois began placing a smaller single letter above the manufacturer’s mark to identify the plant making the bottle. Factories and marks included A (Alton, Illinois); B (Bridgeton, New Jersey); C (Charlotte, Michigan); F (Fairmount, West Virginia); S (Streator, Illinois); and W (Waco, Texas) (Porter 1996:4).Pepsi-Cola Bottles
I have seen no comparable work on Pepsi bottles, so I include my observations here (although Stoddard’s most recent book [2003] contains much helpful dating and historical information). Prior to Pepsi’s adaptation of Applied Color Label bottles (often called painted-label bottles or pyroglazing, in the case of milk bottles), the company did not require any special coding, so all early bottles are marked just like any other bottle from the respective glass companies. However, beginning with the first ACL fountain syrup bottle in 1943, all Pepsi bottles followed a specific format. Although I will use the Owens-Illinois marks as examples, the same basic format applies to other companies as well (although the earliest bottles followed the older formats). On Pepsi bases, a line of numerals and a single letter appears above the logo. The first one or two digits is an unknown code that may indicate the area of the country (the only one I have seen in New Mexico and El Paso, Texas, is 14) followed by a single letter (all I have seen so far are either A or B) followed by a two-digit date code. Generally, another single-digit number will appear to the left of the logo, and a singleor double-digit number will be placed at the right (figure 3). The right-hand number is often (but not always) identical to the date code or to the last digit of the date code. Also, either above or below the logo and the line of code above it is a single letter followed by a three- or four-digit number. This is probably a mold code, although the meaning is currently unknown. From looking at El Paso soda bottles, it appears that plants 9 and 6 were the most active in making soda bottles with the older logo (1929-1959) (although soda bottles were also made at plants 3, 18, 19, and 23). Plants 5, 7, 9, 15, and 20 made soda bottles with the newer logo (after 1955). Oddly, Toulouse (1971:403) claimed that “there were no plants 5 and 19.” However, those numbers appear (with highly legible embossing) on El Paso soda bottles. Two different bottles bearing the I-in-an-ovalsuperimposed- on-an-elongated-diamond manufacturer’s mark bear a “19” in the space to the left of the logo. Similarly, one container with the later I-in-an-oval mark shows a distinct “5” to the left of the logo. It is clear that Toulouse was confused about plant #5. In his table (Toulouse 1971:395; reproduced here as table 1), he lists plant #5 in Charlotte, Michigan, which opened about 1963. Although he calls it an “old number reassigned,” it is likely a new plant number that was skipped earlier. In a table provided to David Whitten by a representative from Owens-Illinois, however, factory #19 is listed as being in Crenshaw, Pennsylvania. The table also included factory numbers as high as 52! Obviously, Toulouse only listed the earlier plants.Exported Jars
Owens-Illinois also manufactured fruit jars. Creswick (1987:107-108) lists several jars made by Owens-Illinois and its Pacific Coast subsidiaries. Jars were embossed on the reverse heel MANUFACTURED BY OWENS-ILLINOIS GLASS CO. or MFD. BY OWENS ILLINOIS GLASS CO. or MANUFACTURED BY OWENS-ILLINOIS GLASS COMPANY. One misstrike read MANUFACTUPED BY OWENS-ILLINOIS GLASS COMPANY. Subsequent evidence suggests that jars and bottles bearing the full name of the company were manufactured for export. Such containers are found as far away as New Zealand – embossed on the bodies with local company names (Lockhart et al. 2005b).Other Discrepancies
In a personal communication, Mike Elling noted that ca. 1944-1945 (World War II) Owens-Illinois seems to have run short of red pigment. Mike has a Royal Crown pyramid bottle that is missing the red that was typically used on the label. Billy Grice offered a yellow-only Squirt bottle on eBay with a 1945 Owens-Illinois mark and date code embossed on the base. He stated that “during the war many west coast bottlers went to single colors.” It is probable that red dye was in short supply during the end of World War II. Owens-Illinois may have only experienced the shortage for the final year or so of the war. One additional discrepancy is worth mentioning. In very small bottles, Owens- Illinois often left off the date, plant, and mold codes completely; only the logo remained. Another exception was provided by David Whitten. He sent information on several pharmaceutical bottles with OI logos and dated paper labels, one of which had the OI logo (no diamond) but only had a single-digit date code. The date code (5) matched the prescription date of 11/23/55. Apparently, on small (but not tiny) bottles, the company reverted to a single-digit date code to save space. David also has several more small bottles with the OI logo and a single-digit date code. The abbreviated date code was apparently pretty common on small bottles. A final discrepancy was also noted by Whitten (personal communication). This concerned a slight difference in the Owens- Illinois logo during the 1930s. The marks tended to be “taller and larger, and the oval is maybe a bit more ‘squared’ or ‘vertically rectangular’ at least . . . compared with later ones.” By the 1940s, however, marks became more refined and smaller. This trend toward reduction in line thickness and increased clarity of the mark and codes continued into the 1980s.Owens Scars
Owens scars, found on the bases of all bottles made by an Owens Automatic Bottle Machine, are discussed in numerous publications (e.g. Jones & Sullivan 1989:37- 38). These scars are caused by the suction process of drawing the glass into the mold, a technique that is unique to bottles made by the Owens machine (on bottles made in the U.S.). As the glass was sucked into the mold, it was sheared of by a “knife.” This shearing action created the scar. These are often described as “feathered” or “rough,” but that does not accurately describe all Owens scars. Although we currently have no documented evidence, empirical observation suggests that this feathering may have been caused by dull knives. Over time, the feathering decreases until most Owens scars consist of only a single line. Probably, technicians learned to change or sharpen the knives more frequently or some other technical discovery allowed for the more refined scar. On later bottles from the Owens company, for example, the scars consist of a roughly circular fine line. Usually, this line is debossed or sunken into the glass (unlike embossing and most mold lines which protrude from the glass surface). However, the Owens scar may be raised above the surface of the bottle. The Owens scar is rarely centered on the base. It is often so off center that it extends over the heel and onto the body of the bottle. This is especially true of smaller bottles, but the phenomenon also occurs on fairly large containers.Conclusion
Thus, we find that the Owens-Illinois coding system is a bit more complex and revealing than we originally thought. The transition period between one- and twodigit date codes is usually clearly marked. This research confirms Toulouse’s date of 1940 for the use of the Duraglas mark and also sets a date (1940) for the use of stippling on bottle bases by Owens-Illinois. In addition, Pepsi-Cola and Coca-Cola required a slightly different date coding, and date codes were either eliminated or abbreviated on some smaller bottles. Owens-Illinois, however, was very inconsistent with its coding.References
