Synthetic Fluorescent Rock: Synthilite II, Synth2.5 - UVc
From the basement lab comes this 3" 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 Synthilite II. To this was added a small amount of sulfur and about 6mL of a hydrated zinc chloride solution. This was mixed in an aluminum foil form. On top was sprinkled some filings from a new US penny (zinc + copper).
After drying in the sun for a day, the sample was covered in foil and roasted over charcoal coals for about 4 hours. The resulting substance was a hard dry dark gray material with many air bubbles created by the aluminum sulfate expanding as it became aluminum hydroxide. The material melted easily from the heat of the MAPP gas torch resulting in a very hard gray ceramic-like "rock". Under UV the rock didn't really fluoresce other than in a few spots where a dark green color was being produced.
It was then topped with a small pile of barium carbonate + sulfur combined with a few crystals of cupric chloride. The pile was then heated with the MAPP gas torch which caused it to ignite as the sulfur burned. As the heating continued, the pile grew more incandescent.
