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. 

Second quality Tubes do not meet our visual inspection standards. May contain one or more of the following: stones, scars, scratches, excessive air content or color inconsistencies.
