Synthetic Mineral Attempt: "Esperite" - SW+MW

This pic shows a 3" foil pan containing an attempt to synthesize a rare Franklin fluorescing mineral, esperite - PbCa3Zn4(SiO4)4 :Mn.

 

The upper image shows the precipitate before it was heated by a MAPP gas torch. The bottom image shows it after it was heated with the torch.

 

Esperite fluoresces yellow/green under SW light. There's a bit of yellow in the heated sample....maybe esperite?

 

Shown in SW+MW light.
