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

 

FOV: 5" wide.

 

On an aluminum tray, salt, sulfur and zinc chloride solution containing trace amounts of copper chloride were combined with a bit of manganese sulfate ssol. and two drops of lead chloride ssol. The sample was then well heated with a MAPP torch until the salt had melted and partially drained off the tray.

 

(~5 drops of Ba(OH)2 sol. were added as flux.)

 

Suspected phosphor: ZnS:Mn,Pb,Cu,Al in NaCl

 

Contains:

ZnS:Cu,Al (FL+PHOS! Green/Orange, Blue/Green/Orange >BL UVab,c)
