These look much better in person and I can't seem to capture the depth or the color with my camera. I didn't make these all in on session and I plan on making more. This is only two colors of glass and one in particular gives all the colors under the clear encasing. It is a process of lots of oxygen and heating and cooling over and over. My concentrator only puts off so much oxygen and it would be interesting to see what I could get if I used tanked oxy instead of a concentrator. It is fun to see the difference in each bead and I could not make them exactly the same even if I wanted to.
