Clear glass Presto one-pint canning jar. The jar is square with rounded corners so that it is almost cylindrical. It has screw threads at the top, and has a brass ring screwed on so as to secure a lid that is made of clear glass with a red rubber seal that meets the jar lip. The mold seams extend from a horizontal seam on the side but very near the bottom up to but not over the lip. Besides the seam near the bottom there is a horizontal mold seam where the top meets the base. Embossed on the side: "Presto Supreme Mason" "Duraglas" "D75". On the bottom: "Owens Illinois Glass Company" "7". Also on the bottom is embossed a diamond shaped logo. On the glass lid: "Presto".
Duraglas was the proprietary name for a process used by the Owens-Illinois Glass Company where the surface of the hot, just produced bottles, were sprayed on the body, shoulder, and neck (not base or the top of the finish) with a stannic chloride vapor that allowed the tin to bond to the outer surface and providing scratch resistance and durability to the bottles.Made/Created
