This powder is the raw material for all glow in the dark crafts.  It can be mixed with candles, resins, plastics, glass or any kind of mostly transparent material that will allow light to reach it.  We don't maintain a stock at this time so please allow extra time for us to order it.  Many different colors, brightnesses and durations are available now, see the options.  Unlike the Zinc Sulfide which is probably used in alot of our pre-manufactured glow in the dark items, this powder is made from strontium aluminate.  It can glow for up to 12 hours and is truly premium stuff.  White and red are also available, but more expensive.  Please call or e-mail for a quote if these are your desired colors.
