NS145 Luna Blue is a clear glass that fluoresces blue under a U.V. light source. This glass does contain some air content, although stable and can be used in any type of flame. 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.
Tubing is sold by the ounce with a minimum order of 8 ounces. Tubes are pulled as close to the weight ordered as possible. Because of the nature of hand pulled tubes, the weight ordered and the weight sent/billed may vary by several ounces.
Please be aware that some tubes may taper or have varying wall thicknesses throughout the tube.
