Uranyl nitrate and sodium chloride from a previous experiment was dissolved in water. Approx. 6mL of this solution was added to ~5mL of dry sodium metasilicate along with water in a small watch glass. This was rehydrated every few days for about two weeks as the sodium silicate would crystallize and then dissolve again. At the end of the two weeks it was dried under a small electric light bulb resulting in a clear glassy substance with a tinge of green color. On the surface formed large crystalline layer. Before the substance dried it was not very fluorescent. After drying and crystallizing, it became very fluorescent yellow-green under all UV wavelengths.
Because of the crystalline nature of the substance, I don't think I succeeded in creating hyalite opal which is amorphous and not crystalline.

Experiments in recreating the Bologna Stone, one of the first synthetically made phosphors made by heating barite from near Bologna, Italy. Heating barite (BaSO4) with carbon reduces it to barium sulfide (BaS).
These "cakes" were made by combining BaSO4 with flour and sugar (plus a tiny bit of NaCl and KCl as fluxes and CuCl2*2H2O as activator). Water was added and the mixture was baked at 500 degF until jet black and no longer producing smoke. The black mass was then and heated with a MAPP gas torch until it glowed bluish white.

After reading a paper titled "The Bologna Stone: history's first persistent luminescent material" I was inspired to attempt to investigate the paper's claim that The Bologna Stone (a "mystical" medieval stone that glowed in the dark) was in reality barium sulfide with a copper impurity.
A small quantity of barium sulfate doped with 1% copper (by mol) was made by combining solutions of barium chloride, cupric chloride with a solution of sodium sulfate. The resulting precipitate was then filtered and dried then combined with carbon (21% by weight) then fired in an alumina crucible over the flame of a MAPP gas torch. The crucible became "pale pink" hot and was fired for almost 15 minutes over two sessions.
The image shows the results after the second firing.

Calcium sulfide made by heating rockshop calcite with hardware store sulfur in molten salt. Manganese and lead were added as activators.
I believe the bubbles in the salt were formed by carbon dioxide gas being produced by the calcination of the calcium carbonate. In the molten state the bubbles glowed a bright bluish white similar in color to the incandescence produced by heating calcium oxide into candoluminescence (aka "limelight").
