Experiment #4 is a clear glass that fluoresces blue under ultraviolet light. This campaign represents our efforts to produce a brighter blue reaction under U.V. light. This glass varies in air content and Seconds may contain some pink U.V. 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.
