Kilner jar was invented by John Kilner. Originally they were just a glass jar, a glass lid plug, and a rubber seal places over it. It then evolved to where you had the glass lid placed on the neck of the glass jar then you seal it all together with a metal screw ring with the rubber seal in side the metal screw ring. Today now the whole lid is made of metal with the smaller rubber seal ring inside the screw on lid. You still can find and purchase the older type jars. Kilner jar main use was for preserving foods, storing/bottling food, and pickling food. Kilner jars are great jars to store your homemade preserves, jams, or sauces.
