Hello, my name is Carol from PA. I have a large jar, perhaps five gallon size. It is clear glass with a large mouth opening approx. 4 1/4" in diameter. Also, it has two small feet side by side on the mouth end of the jar that have been molded into the glass, making it like it could sit it it's side. I have been looking everywhere for another jar like it and I was hoping that someone could help identify it. It is not a water jar but perhaps some kind of chemical jar. I see no markings at all on it. Anyone have any idea's. Thanks
