- Made in USA by Owens-Illinois Glass Company
- Vintage 1930
- Details: A collector’s great find, very rare Hoffman’s Dairy Half Pint milk bottle. Tradition suggests that customers with poor quality ice boxes or no refrigeration were more likely to prefer half- or quarter-pint containers. To arrive at the age of this bottle we took into consideration the following. The raised glass letters, called embossing. The top edge of the bottle has a built-in ledge to support a ligneous (cardboard) disk for a closure, this type of closure was designed in 1889 by two employees of the Thatcher Manufacturing Company in Potsdam, New York. The top of the bottle reads: “MILK FOR HEALTH – IN A BOTTLE FOR SAFETY”. This is most likely due to the 1922 condemnation, by the New York State Tuberculosis Association, of selling “loose milk”, glass bottles were deemed as safer for the public. The bottom markings tell us several things, there are the two large initials “HD” for Hoffman Dairy. There is also the name: Hoffman’s Dairy, Monroe, Mich., embossed on the bottom of the bottle. The markings on the bottle tell us it was manufactured by Owens-Illinois Glass Company, it was made specifically for Hoffman Dairy in 1930 at their Glassboro, New Jersey plant (operated from 1930-1939). The off-center round “scar” at the base of this bottle suggests it was made by blown parison molds. This is true with both Owens machines and later press-and-blow machines. The scars can be faint or distinct, but they are always off center. The word “Registered” is on the bottom edge, most states had laws that allowed dairies to register their milk bottles. A registered bottle meant that it was illegal for any firm other than the originating dairy to use that milk bottle. “Sealed BB48” is also visible on this bottle. We were unable to find information on Hoffman’s Dairy in Michigan, if you have any information, we would appreciate you sharing, we always like to know the history of our items.

Owens-Illinois Glass Company formed in 1929 after Owens Glass Company merged with Illinois Glass Company, this company eventually controlled a vast share of the glass bottle manufacturing market. Their first distinctive trademark is often called the “diamond IO mark,” and is essentially the combination between the Owens Glass Co. and Illinois Glass Co. trademarks: the letter ‘I’ within an oval, superimposed on an elongated diamond.
Embossing consists of raised letters, numbers, and designs that extend above the surface of the glass. From the earliest milk bottles in 1878 to the initial use of enameled lettering, (called pyroglazing in 1934), embossing was the primary method of labeling on any dairy containers.
For many collectors, milk bottles carry a nostalgic quality of a bygone age. The most prized milk bottles are embossed (raised glass lettering) or pyroglazed (painted) with names of dairies on them, which were used for home delivery of milk so that the milk bottles could find their way back to their respective dairies. Milk bottles since the 1930s have used pyroglaze or ACL (Applied Color Label) to identify the bottles. Before the 1930s, names were embossed on milk bottles using a slug plate. The name was impressed on the slug plate, then the plate was inserted into the mold used to make the bottle – the result was the embossed name on the bottle. Some interesting stats:
- The first home milk deliveries occurred in 1785 in rural Vermont.
- The first glass milk bottle was patented in 1874 in the United States.
- In the 1920s advertisements began to appear on milk bottles, etched on the glass using a sandblasting technique.
