I offered no guarantees but said I would try! The above photograph is what happened when I tried a white base, dots of Vetrofond black and dots of sis*, gravity swirled and encased with clear. The "black" when spread out thinly (as gravity swirling is wont to do with your glass), becomes navy blue.The above photograph also uses black glass and sis but this time, the black is made by Effetre. When spread out, it's an entirely different colour, not sure I would describe it as violet but it has probably reacted with the silver in the sis anyway.The above beads are the most black of all, this time I've used Intense Black and it's done it's usual webbing out thing which is sometimes desirable in beads. The photograph doesn't show it that well, but the "black" is blue in places. You can see some top right of the right hand bead and there's also some of the "violet" in the webbing too.
Overall, I prefer the top beads and have made quite a few of these today and they're baking away in my kiln now as I type. They remind me of the colours in a poster that I have on my studio wall of two rare white tiger cubs (aw cute!)
Just as I was coming to the end of beadmaking for the day, some glass I ordered yesterday arrived (always an exciting moment!) I have got three other varieties of black glass to add to my stash:
- Reichenbach Deep Black
- Effetre Silver Black
- CIM Hades
*For non-beadmakers, sis stands for silvered ivory stringer (a rod of ivory glass with silver foil burnished into the surface, melted and then whilst molten pulled into a thinner rod of glass).
