Work it VERY hot until it is transparent on the surface. Then cool and watch it turn a dark orange or brown. Depending on if and WHEN you encase, you will get different colors. If you encase it soon after it begins to turn dark, you will get blues and greens. If you let the dark brown really develop before you encase, you will get more blues and magentas. Depending on how you treat it after you encase, or not, you may get pinks, rose, lavenders and creams. But you have to get it pretty hot to begin with. Use a very neutral flame.

Rod colors vary from beige to green
