Synthetic Fluorescent Mineral Art: Planet Plaster (SrS) - 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 strontium carbonate and 0.5mL of sulfur as well as about 0.03mL of copper carbonate (malachite). After the plaster had set it was heated until bluish yellow incandescence using a MAPP gas torch (gas ran out during heating).

 

The luminescence of this sample was particularly bright making it a challenge to photograph.
