Charles Sweigart of Reinholds, Pennsylvania adds this to the mix.
On the subject of the Carder copper-red color, I found the Bohemian master salt about 20+ years ago and have searched for any matching colored glass since then. It appears to me to be quite similar to the perfume in
question. Others opinions would be welcomed.

The surface of this piece should be described as oily and the red shades from orange-red to red when viewed through the varying thickness of the cut panels. It has an almost flourescent quality in natural light. Has any one ever encountered any other similar colored pieces? How does this compare to the Carder color?
