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 (520nm). Other colors are possible, but green appears the brightest since human eyes are more sensitive to greens.
Mix it with light-colored paints to make objects glow, add to glaze to make glowing pottery, or just leave it in the jar as a fun light.
It is non-toxic and non-radioactive but please do not eat it. Safety data and tips for use are available at boxofmatter.com
Just got this recently and watching the glow makes me giddy with excitement. I can’t wait to use it!
I purchased some very unique items from this small company and am very pleased. They have very unique science-based objects. Great for kids and adult science nerds! Highly recommended!
