I'm curious to learn, after the radium trials and aftermath, what were the compounds used for phosphorescent watch dials and numbers? Were there typical compounds used, or a certain range of compounds used for luminous dials? I understand that these questions likely fall under "proprietary" info, but as time's passed, what was used I imagine has now just become horology trivia. Leo Horishny Sun Valley, NV | ||
