This glass was all but extinct, but Val Cox Frit is now selling a new version. I have found the new blend to be just as lovely and very similar to the original.
“Purple Rose is back and this one is a dream to work with. Not prone to devitrification as Zimmermann’s original (Z99). Beautiful variegation between purple and blue violet. For best results, use an oxygen rich flame and cool slowly. This is a #1 grind but very close in size to the original Z99 #0.”
Val Cox Purple Rose frit swirled in Kugler K100 clear. The stringer decoration was pulled from the frit in the clear as well.
