More about this item
This is a rare 1931 Presto canning jar, not a reproduction. Presto Supreme Mason Square Half Gallon Canning Jar, Aluminum Ring and Presto Glass Lid. Fruit Jar, Mason Jar, Canning Jar Collection Made in 1931 in California, USA. Jar embossed on front side: Presto Supreme Mason embossed on the back: Manufactured by Illinois Pacific Coast Co. embossed on front heel: 7505, IPC mark in triangle, 1 (this is a rare mark) Two-piece lid: Aluminum ring with window for viewing the Presto name on the glass insert. Embossed on the glass lid: Presto Embossed on the aluminum ring: "The Presto Jar and Closure are approved by the Good Housekeeping Institute. Serial No. 1205, Conducted by Good Houskeeping Magazine." Illinois Pacific Coast Company operated 1930 - 1932. The company name was changed to Owens-Illinois Pacific Coast Co. on April 23, 1932. From online research, this mark was used only in 1930 - 1932. The IPC mark in triangle is not found on most online glass mark lists. The number 1 to the right of the mark indicates manufacturing date 1931. (sources: www.blm.gov/historic_bottles/pdffiles/IGPCO_BLockhart.pdf ) ( and: www.sha.org/research/owens-Illinois_article.cfm ) I thought that square canning jars came into use in 1942, during World War II, (The WWII war board required all glass manufacturers to adopt this shape). But discovered that "Square jars were made by many manufacturers as early as the 1890s. Although they took up less space in the pantry they were never as popular as the regular canning jars and so are a little rare making them a little higher in value." (from antiques.lovetoknow.com ) Size: about 9.25 inches tall without lid; base 4.25 inches wide; top 2.5 inches diameter. Weighs almost 2 pounds unpacked. Condition: Good. Has one small chip (1/4 inch long) on outside top rim, which does not interfere with screwing on the lid (see photo). No other defects. Glass is clean and shiny. I have had this Presto canning jar since the early 1970s, when I acquired it from its original owner. (She was in her 80's at the time.) USPS Priority Mail with Delivery Confirmation.
