1 is a spacer over clear and 2 is over white. 3 is over white with silver foil melted in, then reduced. I had noticed this effect with standard cobalt and wanted to see if it did the same thing. It does.
4 is a test to see if applying silver foil, melting it in and reducing it brought out the blue. I was surprised to find out it did, just barely. 5 is the same as 3, encased in clear. I was sorry to see that the effect wasn't really preserved, but there is some lightening of the blue. 6 is over ivory with ivory dots. The blue is so dark it's hard to see if there was any interaction between the 2. I don't think there was, based on the crispness of the edges of the ivory dots. 7 is with copper green and nothing changed on either side. 8 is with turquoise and nothing happened here either, but I got a nice thin dot on top. This is an idea--use the color to place over white on a cobalt blue bead so the dots on top of the white look as intense as the base bead color.
I like the way 9 turned out. It is dots of TE-331 with clear dots on top of half of them. I didn't make any special effort to strike the TE-331, and wouldn't you know it, it is my best color reaction to date. I wonder if I can do this again?
Would I get more of this glass if it were available? I don't know. The glass I have will last a long time, since it is really only visible in very thin layers. It would be good for fine stringer work or in murrini but that's about all I can see using it for. I can't make murrini so pulled cane and over other colors is about it.
