These mason jars are my Daddy's. After I opened this aqua colored one, I went online and it really looks as if this one is from 1910 or 1915! How many people have used this one jar? How many hands have touched it? What made them stamp that word "Perfect" upon these early jars? I can't find an explanation for it. Apparently, the blue color is from iron imperfections in the glass but I think it is lovely. There is also a small bubble in the side, and that is another indication that it is an early piece.
My Dad knows that this is an old jar but he USES it still. I love beautiful things but I love useful things too! These jars will be returned to my Dad when they are both empty and hopefully, will be refilled with wonderful food from his garden. Now, that is what I call PERFECT.
