I tried a small sample of Mike F's new vetrofond called Silk. It is a translucent clear, which seems very easy to work. I don't have much experience with opalino or alabastro, so I can't compare with those. I made a small donut with light aqua dots. The base bead appears to be etched, and the dots show up very well. I hope I can post a picture this afternoon. I need more of this Silk.
