Vintage Owens-Illinois Duraglas Clear Glass Utility Jar

This is a mid-20th-century clear glass storage or utility jar manufactured by the Owens-Illinois Glass Company. The item features the 'Duraglas' branding, a proprietary glass-making process introduced in 1940 that utilized a specific annealing technique to increase surface strength and durability. The jar has a cylindrical body that tapers slightly into rounded shoulders leading to a threaded neck. It is topped with a distinctively styled clear glass lid featuring a raised decorative pattern around the perimeter, likely designed for better grip. The glass is transparent with no significant discoloration, though the base shows embossed markings consistent with Owens-Illinois production, including the diamond-O-I logo. The construction is machine-made with visible mold seams and a thick, weighted base for stability. In terms of condition, the jar appears in good vintage state with no major cracks or large chips visible in the photograph, though typical shelf wear, minor abrasions, and a slight patina inside the base from use may be present upon closer inspection. The style is utilitarian yet classic, reflecting the mass-produced household glassware of the 1940s to 1950s. The quality of the pressed glass is high for a commercial container, indicative of the era's robust manufacturing standards.
