Today is: National Mason Jar Day
- Oops!Something went wrong.Please try again later.
National Mason Jar Day — created by Misty Campbell-Olbert, the founder of Unboxing the Bizarre — celebrates the jar used for canning and countless other purposes and takes place on the anniversary of the day John Landis Mason patented it in 1858. It seems that the importance of the patent and its date was known early on, as Mason jars were embossed with that information well into the 20th century.
Prior to the invention of the Mason jar, and even after its invention to some extent, glass jars were often sealed with wax — a type of sealant that was many times faulty. The Mason jar was an improvement because of the airtight function of its screw-on-lid. These lids consist of a metal band or ring, which holds down a tin-plated steel disc.
