If you spend any time at all on Pinterest, you will know that all you need to have a perfect home is burlap, chevron, and Mason jars.I can’t tell you how many posts I have seen that list 101 Uses for Mason Jars…of course, most of them don’t actually involve canning.
While canning jars have been around for a long time, it wasn’t until 1858 that the screw-on lid was created.
Prior to that time, flat tin lids were attached to the jars with wax rings.
John Mason was a tinsmith in New York and perfected a machine that would cut threads into the lids, creating a jar with a reusable, screw-on lid.
This process was easier and more reliable than the tin lid and wax method.
Although other companies began creating the jars, Mason held the patent, and so the style of jar became known as a Mason jar.
Clamped Glass-Lid Jars (Lightning Jars) In 1882, Henry William Putnam of Bennington, Vermont, invented a fruit jar that used a glass lid and a metal clamp to hold the lid in place.
These “Lightning jars” became popular because no metal (which could rust, breaking the seal or contaminating the food) contacted the food and the metal clamps made the lids themselves easier to seal and remove (hence the “Lightning” name) .
There were many similar glass lid and wire-clamp jars produced for home canning all the way into the 1960s.
Many can still be seen in garage sales, flea markets and on specialty food jars today.
