I think I finally got the hang of Rubino Oro! This "cranberry" or "ruby gold" glass gets it's color from real gold. It's kind of difficult to work with, and after several tries finally I finally turned out this batch. These are for a friend, but I think I'll have to make more.
These are "stacked dot" beads, mostly. There is a poked bubble up there and a solid color bead, from when I was just messing around. Black base, layered Oro Rubino over white, with random transparent pink center dot. What worked was working further out in the flame, with more oxygen. I needed to let the beads get fairly cool before reheating them to bring the color up. It took a few repeats to get it good and dark.
