Synthetic Fluorescent Rock: Alkali Halide Melt on Scoria - UVc

From the "lab" comes this 4" wide specimen. It consists of salt, calcite, gypsum and epsom salt melted on red scoria. (Perhaps it should be called an alkaline earth melt.) The orange fluorescence is likely due to CaS:Mn2+. This orange fluorescing phosphor was given the name "orangite".

 

Contains:

Orangite (FL+PHOS Pink/Orange >UVc)

 

Shown under UVc light.
