red glass burnout

How do I prevent my red glass beads from burning out? I'm using different types of transparent soft red glass but can't seem to work it for long enough without it turning dark, brownish and with a bloom on it.
Any ideas?

With boro, I coat my opaque colors in clear to reduce bubbling at high temps. Some glass will strike to a darker color when hot and return to original once cooled. Not sure for soft glass tho.

Thanks, I have tried casing the red in clear but that seems to lengthen the work time and increase the heat required. I'll try casing the rod and see what happens then. K

Sounds to me as if you are using soft glass. In that case the red will fade out when you work with it like you say. However, you can get the color back by letting it cool down a bit and reheating it. You can't really shape it again at that stage, but it should bring back your nice transparent red color.
Anyway, it differs from glass to glass how much you can get back. Works better with some rods and not as good with others. At least, that is my experience.

red glass will look brown when being worked using 104 soft glass, once you have made your bead, let it cool so the outside no longer glows then flash it (put it back into a hot flame) heat it up not to a molten runny consistency but just until its hot, dont reshape etc, cool and anneal the red colouring will then return by the time its cold
