However - this glass seems to develop a greyish streakiness that does not go away by itself.
First off - the rod. This is a very dark, very dense red. Garnet usually is.
This looks quite orangey - but is strongly side-lit. You can definitely see where it has developed colour unevenly though.
I decided that with that little stumpy end, I wanted to see what happened if I melted it clear - got it so hot that it went clear. And this is the lovely little jewel that resulted. I got it drippy hot, completely clear, wound off the bead, and watched it cool and go red before my eyes without striking. And popped it in the kiln. Beautiful!
And with the tiny bit I had left - you just can't get it that hot and put it on the wire - the wire won't handle that kind of heat - due to being that much thinner. I encased it, and pulled it - which cools it quite quickly. I got some grey streaks and this time - spent rather a lot of time trying to re-heat them and strike them out. Fortunately, that reduced them significantly - although I won't say they are completely gone.
Not sure what to make of all this. Definitely a glass that can challenge you. The spacer bead is gorgeous, in other applications - you are going to get different results.
