The Duraglas Half Pint Milk Bottle is a quintessential piece of mid-century Americana, manufactured by the Owens-Illinois Glass Company using their revolutionary 1940s strengthening process. These bottles are highly collectible because they represent a major technological shift toward lighter, more durable glassware capable of surviving high-temperature sterilization in the dairy industry.

What Is Duraglas Half Pint Milk Bottle Worth?

The typical price range for Duraglas Half Pint Milk Bottle is $10 - $11 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

  • Condition of the glass, specifically the absence of chips or heavy 'case wear' from industrial washing.
  • Clarity of the embossed 'Duraglas' lettering and any specific dairy plant markings.
  • Presence of original painted pyroglaze labels, which can increase value over plain embossed versions.
  • The integrity of the reinforced rim, as these were prone to nicks during the capping and uncapping process.

How to Identify Duraglas Half Pint Milk Bottle?

  • Look for the 'Duraglas' script logo embossed on the heel or base of the bottle.
  • Verify the half-pint capacity, characterized by a compact round body and a reinforced rim designed for heavy reuse.
  • Check for the Owens-Illinois Glass Company maker's mark, typically an 'I' inside a diamond and circle.
  • Confirm the glass is clear and features the specific structural thickness associated with the 1940-1950 production era.
