Default Re: Rejuvenating Magic eye Valves?

I note that there has been some research done on rejuvenating electroluminescent displays which are using a very similar phosphor, and this suggests that annealing at a temperature of between 180C and 240C does significantly help (maybe takes about 2 hours, and the temperature is fairly critical - don't overdo it).
