Rhenium doped phosphate glass!

For the first time and after many unsuccessful attempts I was able to incorporate a small amount of Rhenium (~ 0.6 - 1 mol%) into an aluminum barium phosphate glass without immediate reduction to black Re.
On the right you see the colorless and transparent glass with fully dissolved Re in the +7 state. On the left there is the same glass where Re formed nano clusters after slow cooling under slight reducing conditions.

The picture below shows the pale yellow luminescence of the colorless glass under 257nm UV irradiation.

Very impressive! Is Rhenium known for fluorescence in glassy materials?

Very exotic: Erbium doped Barium Sodium Magnesium Bismuthate glass.

This glass consists almost entirely of Bi2O3 containing no other glass former. This is my first stable and reproducible bismuthate glass.
The very aggressive glass melt even attacks a Platinum crucible!
The 1 mol% Erbium oxide makes it suitable for infrared optics.
Its a very high density glass. The smallest bead in the picture weighs exactly 2 grams!

Neon discharge tube.
Every time I fire them up for the first time after sealing I fall in love with the deep red color.

Rare Purple Gold

Purple Gold is an Alloy of 80% Gold and 20% Aluminum with the average formula Al2Au which is fused under high vacuum to avoid oxidation of the aluminum during fusing. There is only one try and not every attempt is rewarded with such nice and shiny surface

I am wondering as a Jeweller if this would be workable, if it would keep its colour after the various annealing Heating processes gold has to go through to fabricate a piece of Jewelry, interesting i would so love to make a ring from this.
