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.
Because there were so many, including a couple of Arc France jars, we had our pick of the litter and scrounged around looking for those with the best gaskets and wire clamps. I learned that these are called bail tops, or lightning closures. They are an extremely effective and easy way to tightly close up a jar!
Even the hinged tops of the jars were beautiful, with their scripted print. Parfait is French for "perfect", so I suppose these are the perfect super jars!
I just love their shape, with their bulbous bottoms. Le Parfait actually still makes jars for canning and general uses, but I don't think the modern ones are as nice as these! =) It is helpful to know that there are replacement gaskets available. An interesting fact is that the orange gaskets are trademarked by the company since it made consumers recognize these as Le Parfait jars.
I'm still pinching myself about this, but this thrift store has low prices and was still holding a half price sale. I got both of these beauties for 55¢. I know this post is a bit picture-heavy, but I just had to share!
Linking up to ATG's Thrift Share Monday!
UPDATE: I have finally found some vintage Ball mason jars - if you are interested, check them out here!
