CBS Blue Glow Pigment 1 oz

This glowing powder is a fantastic addition to flameworked glass - I've personally only used it for borosilicate, but it may be compatible with other types of glass as well. After 10 minutes in sunlight, it glows quite brightly for ~4 hours.Tips for use: don't expose to bare flame, especially under oxidizing conditions. My usual method is to put some of the powder inside of a small tube, then flame the tube enough to melt it into a solid rod. When exposed to flame the powder flashes red, off-gasses a strange-smelling vapor, and loses its magical glow.
