Original Message:   Copper ruby vs Selenium/Cadmium and "striking"

Re-reading Rick Sprague's Beads:Journal... article 1990 Vol.2, found this: "The demonstration was of the making of a small, teardrop-shaped ear bob. This item is made without a wire insert from a clear-glass rod that turns ruby red when heated." Am I mistaken in thinking that lead glass with copper [later: gold glass also strikes to ruby] is what requires reheating to "strike" the color? This is not necessary with selenium/cadmium ruby glass? Could the duskier red beads on the left in my photos be copper red? Copyright 2024 All rights reserved by Bead Collector Network and its users
