Mine arrived a few days back and so far, I have only been able to melt the Trans Cranberry and the Rose. Very pretty! I did have to be sure and work them cool, but I too tend to work hot anyway. I have a few other colors I want to try out when I get the chance.
AFA annealing goes, I batch anneal and have had no problems. The beads I posted pics of in one of the other threads are still fine. I don't use vermiculite though, I never have trusted it.
I use blanket, doubled and wrapped in a towel for added insulation.
Hopefully this can be a positive thread for those of us who choose to try it out.
