Synthetic Fluorescent Rock: Synthilite II, Synth2.1 - UVc

From the basement lab comes this 2" wide specimen.

 

Salt, Aluminum Sulfate, Magnesium Sulfate, Sodium Metasilicate, Sulfur and a small amount of Sodium Hydroxide was combined with water and allowed to evaporate for a few days. This produced a thick viscous yellow liquid that easily formed small crystals.

 

This liquid formed the "base" for Synthelite II. To this was added a small amount of strontium carbonate, sulfur and a bit of manganese sulfate solution. This was roughly mixed in an aluminum foil form. On top was sprinkled some filings from a lead fishing sinker and filings from a new US penny (zinc + copper).

 

This was then heated with a MAPP gas torch until incandescent and the foil was burned away.

 

The resulting rock was chalky and brittle.
