I was out thrifting with a friend when we came upon a mass of vintage mason wire clamp mason jars! When I say mass, I mean that there were about a dozen jars, embossed with "Le Parfait Super" in a beautiful raised script on the glass.
The jars are made in France, and their volume was written in metric on the base of the jars. They could have been used for canning preserves, as the rubber gasket would be boiled, the contents closed in, and then heated to create a vacuum seal.
