After playing with the CiM Auburn - I had a couple of questions about it still - so I went back to the torch to experiment with it some more.
One question I had was: How would it look as a white-cored cane; and the other was: How does it encase, because, once you've been lampworking awhile, you realize that opaque red has a tendency to be unhappy about being encased. You may remember that using Auburn thin enough does reveal it to be a transparent, but it is dense enough that it will read as an opaque. (Many of the "Hot" colours, opaque yellows, reds, oranges don't handle being encased well - and can crack. The usual fix for this is to make a clear core bead, encase it in a thin layer of the troublesome colour, and then encase in clear. This reduces the amount of iffy colour to a lower percentage of the glass and usually allows you to get away with it. Some of them look paler when encased - this does not, however, fix that.)
Here is the white cored cane.
BTW - these pics were shot under a hot, incandescent light to show the red colour.
