The Reichenbach Multi Glass has a gorgeous teal green with shades of purple, blue, and aqua. The outcome of color is definitely due to the heat. It was not harder to achieve colors. I notice the dots placed within the black glass had more color than the surrounding glass.
The rod was a bit thick, approximate 8mm or so, but it wasn’t shocky. It also played well with the black dots. The stringer in the swirl beads had the most color variations. In the bead above, I used EDP, but the color looks more orange than pink.
