I have fallen in love with another silver glass that goes by the name of Arke (by Double Helix glass).
I have only made a few beads with it, using shards, and I have got the most spectacular range of colours from it. I also made a bead that encased the shards in clear glass. I lost the rainbow of colours, but what I got was an extra shimmery look to the bead (the photo does not do it justice).
This is what I 'm talking about.
The silver in the Arke shards has actually fumed some of the black base to a metallic blue, you can see the effect around the murrini.
