Hello !

We are looking for photoluminescent (phosphorescent, not fluorescent) pigments suitable for glass blowing. Of course, after googleing the web we find some providers, but in many cases they just presume their pigments will be ok for glass blowing, i.e. will resist to a 1200 deg Celsius temperature. In one case (Glowglass LLC, managed by Joe Imler), we ordeer and paid for some samples which we never recveived...

That's why I'm asking this forum for advices from people who do test photoluminescent pigments in glass blowing. Can you suggest us some sellers with if possible references ? Is there any special tricks in using tthem ?

Many many thanks in advance !!
Luc
