I first reviewed it many years ago - hmm - I think I may have lost track of how long I have been doing this - anyway - I was investigating yellows and it was part of my comparison.
Anyway - the conversation was about Vetro 910 and how it looked green over black - probably due to an optical effect - rather than a chemical reaction between the glasses.
As Vetro 910 is a yellow that goes a goes a cooked squash colour - I thought this warranted investigation.
The rod itself appears to be a transparent with a core and an outer skin. I don't know what happens if you slice it up as murrini, however.
Trails of it over black, (Hades, I think) - give you this, however. Interesting, no? Lots of webbing too.
Ah - the nice safe, security of making my monochromatic bits on wire - no worries about colours playing nice together and I can just enjoy the streakiness!
