Synthetic Fluorescent Mineral Experiment/Art: Partiyte_11 - UVc

 

From the basement lab comes this 3.5" wide specimen.

 

On an aluminum tray containing a bed of melted salt + NaNO3 {~2 grains} + PbCl2 ssol {2 drops}, SrS mix was spread in a thin layer in the center and CaS mix was placed in a ring around it. The sample was then well heated with a MAPP torch until most of the salt had melted.

 

SrS mix: AA SrCO3 {1 spn}, S {1 spn}, NaCl {1 spn} + AgNO3 {~3 xtls} + PbCl2 ssol {1 drop}

CaS mix: fresh CaCO3 {1 spn}, S {1 spn}, NaCl {2 spn} + MnSO4 ssol {1 drops}

 

Contains:

SrS (FL+PHOS Green/Yellow/Greenish yellow >UVabc)

CaS (FL+PHOS Orange >UVabc)
