Canning Jars

Hi all, I thought I'd share this image of an 1858 canning jar made by John Mason. His jar was the first to have the twist on lid with a metal lid. A gasket was placed on the top of the canning jar before the lid was screwed on. I found this image of this 1858 Mason jar on sale online in wonderful condition. It's an interesting insight to how soon these kinds of jars were available for canning food for the home-maker.
