Glass pint-size 'Kerr Self Sealing Mason' canning jar

Kerr Glass Manufacturing Corporation began producing self-sealing mason jars in the early 1900s, with this embossed style becoming popular from the 1910s through the 1940s. These jars were essential household items for home food preservation, allowing families to safely can fruits, vegetables, and other perishables. The self-sealing design featured a two-piece metal lid system that created an airtight seal during the canning process. Vintage Kerr mason jars appeal to collectors of antique glassware, kitchen memorabilia enthusiasts, and those interested in the history of American domestic life. These jars are valued for their nostalgic connection to traditional home canning practices and their simple, functional design. Collectors appreciate variations in embossing styles, sizes, and the historical evolution of the Kerr brand, making them popular items at antique shows and online marketplaces.
