Synthetic Fluorescent Mineral Experiment/Art: Partiyte_17 - UVc


From the basement lab comes this 3.5" wide specimen. 3rd attempt to create a "rainbow rock".

On an aluminum tray CaS:Mn, SrS:Pb and CaS:Cu were spread in a thin layer from left to right. The sample was then well heated with a MAPP torch until the salt had melted.

CaS:Mn mix: fresh CaCO3 {1 spn}, S {1 spn}, NaCl {1.5 spn} + MnSO4 ssol {1 drop} + PbCl2 ssol {1 drop}
SrS:Pb mix: AA SrCO3 {1 spn}, S {1 spn}, NaCl {1.5 spn} + PbCl2 ssol {1 drop}
CaS:Cu mix: fresh CaCO3 {1 spn}, S {1 spn}, NaCl {1.5 spn} + malachite {few grains} + PbCl2 ssol {1 drop}

Contains:
CaS (FL+PHOS! Orange >UVabc)
SrS (FL+PHOS!! Yellow/Yellow green >UVabc)
CaS (FL+PHOS! Blue/Pink >UVabc)
