This clear glass pot was made by Pyrex in the late 1950's or early 1960's and may have originally been sold as a set with a smaller pot to be used as a double boiler. For sale here is one clear pot with lid, in excellent condition with no scratches, chips, or stains, only a small amount of minor scuffing on the bottom of the inside which may be a touch of limescale from hard water.
This pot is a unique piece which allows you to see how your dinner is coming along without having to lift the lid, and glass pots don't hold on to smells and clean up more thoroughly than steel.
