Duraglas Glass Jar Value Guide

The Duraglas glass jar is a quintessential piece of mid-century Americana, produced by the Owens-Illinois Glass Company between 1940 and 1960. These jars are highly collectible due to their specialized 'Duraglas' strengthening process and their functional design featuring a wire bail handle and threaded metal lid.

What Is Duraglas Glass Jar Worth?

The typical price range for Duraglas Glass Jar is $25 - $25 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Condition of the metal components, as rust or corrosion on the wire bail and threaded lid can decrease the $25 market value.
• Clarity of the glass, with cloudiness or 'sick glass' from mineral deposits reducing appeal compared to crystal-clear examples.
• Presence of original manufacturing marks and date codes that pinpoint the jar to the 1940-1960 production era.
• Structural integrity, specifically the absence of chips around the threaded rim which is vital for the jar's historical canning function.

How to Identify Duraglas Glass Jar?

• Look for the 'Duraglas' script logo embossed directly on the glass body or base.
• Check the bottom for the Owens-Illinois 'I' inside a diamond or circle mark, often accompanied by a plant code and year digit.
• Verify the presence of the original wire bail handle and the specific threaded metal lid used for 1940s-60s food preservation.
• Examine the glass for the characteristic clarity and thickness associated with the Owens-Illinois industrial manufacturing process.
