This 46mm long bead was made in 3 separate layers, and took me quite a long time to make. I started with a long tapered bicone that was green in the middle and blue on the ends. I shaped it carefully as if it were the final shaping. Then I used the strip casing method to encase the whole thing with clear, possibly using a transparent blue on the ends (it's been a while) to intensify the blue underneath. I like that method because it results in a thin layer of clear on the bead.
Once the whole encased bead was nicely shaped, I applied twisted cane (twisties) that I made using raku and black or blue chalcedony and black, one side at a time, near the ends of the bead. As in Trey's class, intense, focused heat and gravity is applied to the twistie to get it to flow toward the center of the bead, elongating the stripes. A lot of reshaping is necessary after doing this as the mass of glass gets very distorted. When I'm done with this the stripes have essentially met in the center of the bead. Then I spent some time playing with heat and O2 to get the raku or chalcedony to "bloom". I applied a goldstone stringer (this is also encased) around the center of the bead.
Then I used a clear glass stringer to twist around the center of the bead in five different spots. On top of each twisted spot I applied a dot of silvered glass (likely Triton or Psyche), poked it with my tungsten pick, and put a dot of clear on top.
The final task was to apply dots of reduction stringer (likely iris gold) on the ends of the bead. That's it! Easy peasy and only an hour to do.
