Experimental UV Off-Color


Experimental UV off-color is a clear glass with inconsistent UV reactivity resulting in a mixture of bright yellow and pink rods under ultraviolet light. As flame stable glass this color will result in a salmon orange UV reactivity when worked. These rods vary in air content and will not be reproduced in the future. We recommend using an ultraviolet L.E.D. flashlight with a 365Nm-395Nm range for the brightest UV reactivity. Uranium is used in this glass.
