Synthetic Fluorescent Mineral Experiment: Gorn Powder-SrS:Cu,Pb on Rockyard Calcite - UVc

FOV: 4" wide.

 

Approx. 1mL of strontium carbonate, 1mL of sulfur, about 1mL sodium nitrate, 1mL of sugar, 0.01mL of lead chloride and about 0.01mL of copper carbonate was ground together and half the mixture was placed on top of a piece of calcite. It was ignited with a MAPP gas torch and immediately burst into bright yellow flame. The boiling mixture was heated to incandescence. This resulted in a hard dark grey melted substance that was quite luminescent.
