Synthetic Fluorescent Mineral Experiment: Sphalerhalite with CaCl2 and Mn - UVa

 

FOV: 5" wide.

 

Zinc chloride from pennies and calcium chloride from limestone (digested by muriatic acid) was combined with sulfur, NaCl and 3 drops of MnSO4 sol. This was melted with a MAP gas torch.

 

Contains:

ZnS:Cu (FL Green >UVabc)

ZnS:Mn (FL Orange >UVab)

CaS ?
