I’m guessing 1920-30’s

Love how it says "tight" on the lip.

Loose lips sink ships was what I was taught. Lol! It says tight on both sides buddy. Thank you for your kind comments.

That's a nice one! I was always told that they stopped using manganese in the glass around the first world war, so I'm guessing this one dates to the first half of the 1910s since it doesn't look much older than that.

The glass is purple. Not irradiated. From what I was told.

According to the "Fruit Jar Works" made between 1910 and 1913 by the Elk Flint Bottle Co. of Shingle House PA. and has a Red Book # of 1391 valued between 10-12 . That one must have set in someones sunny window for a long time to turn that color, glass was originally clear.

so they did not make these in amethyst at all? This was what I was told. That is why i am asking.
