Glow-in-the-dark Glass Glow Powders can be used in lampworking, fusing and off hand glassblowing. All seven colors are compatible with all soft glass, including ASK, Effetre (Moretti), Vetrofond, Lauscha, Bullseye and Satake. All seven colors are compatible with hard glass, including Glass Alchemy and Northstar borosilicate. However, Orange and White are difficult to use with hard glass and are not recommended. Glass Glow Powders are non-toxic, non-radioactive and non-carcinogenic. Glass Glow Powders are charged by shinning light on them. Any light for about one minute will give short term glowing. Strong sunlight for about one hour will charge the glass long enough to glow for hours. Instruction sheet for use.
