Synthetic Fluorescent Mineral Experiment: Gorn Powder-SrS:Mn on Chalcedony - UVb

FOV: 4.5" wide.

 

Approx. 1mL of strontium carbonate, 1mL of sulfur, about 1mL sodium nitrate, 1mL of sugar and about 0.01mL of manganese carbonate was ground together and placed on top of a piece of chalcedony. It was ignited with a match and immediately burst into bright yellow flame which burned for a couple of seconds. This resulted in a hard grey melted substance that was quite luminescent.

 

This mixture was named "Gorn Powder" in reference to a Star Trek episode wherein an alien (the Gorn) was defeated using a mixture of a nitrate, sulfur and carbon (aka "black powder").
