Europium Glow Powder
You Save: $2.00 (13%)
Shine a bright flashlight (like the one on your cell phone) directly onto the side of this jar of powder for a few seconds and remove it to see something amazing.
This is a new generation of phosphorescent powder that can glow 10x brighter and 10x longer than traditional glow-in-the-dark materials. It glows bright enough to be easily seen in daylight, lasts up to 30 hours, and can be recharged indefinitely.
It is produced by doping strontium aluminate with europium while heated using molten salts to form nanoscale crystals. These crystals absorb light from across the spectrum, which they then re-emit slowly at a specific wavelength.
Mix it with light-colored paints to make objects glow, add to glaze to make glowing pottery, or just leave it in the jar a to impress guests.
It is non-toxic and non-radioactive but please do not eat it. MSDS (pdf)
Note: The green pigment glows the brightest and longest since our eyes are more sensitive to greens.
