Synthetic Fluorescent Mineral Experiment: Planet Nitrate (BaS) - UVc

 

FOV: 3" wide.

 

15 mL of Plaster of Paris was hydrated with 7.5mL of a solution of 1mL sugar and ~20 crystals of CuCl2. On top was added about 1mL of barium carbonate, 0.5mL of sulfur and about 0.5mL sodium nitrate. After the plaster had set it was heated until bluish yellow incandescence using a MAPP gas torch. While heating, the mixture on top 'exploded' leaving a small amount remaining.

 

The luminescence of this sample was particularly bright in the red, having one of the brightest responses to blue.
