A long time ago, someone created this blown glass decanter. It has no marks that I can find, other than the marks for sterling silver on the collar. When placed under a black light you can see how beautifully it glows. When it was blown, the glass had flint in the formula. That's what is causing the glow. With the stopper in place the height is 13 1/2". There is shelf wear to the bottom, which you can expect to find on old glass. The glass itself is remarkably nice and clear with no damage of any kind. It's in excellent condition!
