Synthetic Fluorescent Mineral Experiment: Jackolite in stages - UVa

 

From the basement lab comes this 2.5" wide specimen.

 

On an aluminum tray, salt {~15 mL}, washing soda and sulfur were heated until the salt had melted leaving a mustard yellow mass that smelled strongly of hydrogen sulfide.

 

On the sample was then placed a solution of calcium chloride containing a drop of MnCl2 sol and a drop of PbCl2 ssol. which was absorbed into the yellow mass turning it whitish. The sample was then reheated until the salt had melted.

 

Suspected phosphor: CaS:Mn,Pb

 

Contains:

NaCl:Cu (FL+PHOS Lavendar,Pink,Orange >UVa,b,c)
