Luna Blue - ODDS - Northstar
Luna Blue is a clear glass that fluoresces blue under a U.V. light source. We recommend using an ultraviolet L.E.D. flashlight with a 365Nm-395Nm range for the brightest blue glow. No uranium is used in this glass.
Second quality glass can have the properties of odd quality glass, but may also have small stones, air bubbles, vary in tone/shade, or the shape can be very out of round. Both odd and second quality glass can provide a great value to the right person.
