I have spent a lot of time searching for this mark on the bottom of other ball perfect mason jars on the internet but can't find another linke it. It looks like a + o - or positive sign 0 negative sign. I'm stumped can someone tell me more about this mold marking?
Hello..What I Can Tell You Is That Your Marks Are 'O' And 'X'..The Are Purely For Mold Identifying Purposes, Positioning Of The Mold. The Ball Brother's Began In The Late 1800s With Glass Jars For Canning.
