While I'm thinking of it I wanted to tell you all a neat way I have found to get around overworking a color in the heat until it blisters or starts devitrifying and turning matt... something I am forever doing it seems!
You can pull thin stringers of Devardi clear and wrap-encase your bead and it removes the blisters and matt finish. I encased this hollow blue bead before applying the white stringer, and it provided a softer surface for decoration to stick to and it covered any blistering.
Hope thats a useful option for some to use! Let's keep giving each other tips and info on glass as we come across them.
