INVENTION
An original glass jar canning method begins with a story that is 200 years old. The technique was invented in 1810(1). A (competitive?) inspiration by Napoleon Bonaparte began in 1795 also brought results 15 years later with metal cans.(2)
The original glass jar had no thread to grip a metal closure onto it. Required instead was sealing with paraffin wax since the canning system had no other means of closure. The paraffin wax seal could last for up to about six months.

Progression
Actually, about 50 years later in 1858, John L. Mason (of mason-kerr-ball jars) invented a threaded lip jar along with a two piece sealing lid. The result of this invention allowed for a vacuum seal that was essentially sterile. Thus a long lasting storage system became available. Documentation and directions about this is much easier to find in future writings.
Quote from ‘Home Canning with Paraffin Wax’
Paraffin Wax: Short Term Method
As a temporary sealant mentioned above, paraffin was available. But for long term storage, a paraffin seal was not the safest way to seal a jar. Mold could form if the seal was not air tight.
Traditionalists like Homestead Tessie like this old fashioned method. She scrapes mold off the top of jam so as not to waste the entire jar. ‘Waste not, want not’. Traditional canning is part of her intentional homestead lifestyle.

Dangers Due to heat and cold, expansion and contraction also posed a liability. Lastly, botulism and even death were extreme, out of the ordinary, possibilities. But this wax technique was adopted by Survivalist Preppers for dire circumstances. It is demonstrated in the video below.

Keeping Traditions
Originally paraffin was the only seal available with jar canning as shown in the video above. It is a system that can be used ‘if the grid goes down’. Once safer methods were available, wax was not necessary. In spite of this, there is more to the story.
Actually, this traditional system is still practiced today. It is demonstrated in the video below. The author also explains why she likes to use it.
