Original Message:   Re: Generally it's helpful when one hopes for input about their bead or beads....
I discovered this bead currently being offered on-line and it is described as a Roman crumb glass bead circa 1st century A.D. Of course, perhaps it's authenticity could be questioned as well. It does however have raised red and green bumps that seem to have faired better than the body of the bead. So what shade of red is appropriate for ancient beads? Is there a time line for the shades of red glass that were used? I know just a little about how the shade red has changed in Venetian beads. One site mentions how, "newly discovered Selenium was used in the production of the translucent red outer glass between approximately 1890 and 1930, giving a more garish ruby red outer color. Its use was discontinued when it became more expensive than the gold which had been used previously." So, I'd be very interested to hear what anyone knows for certain about the color red in terms of ancient glass...facts, not conjecture. Please, let me have it.
