The science of glow powders:

• Strontium Aluminate is a molecule made from Strontium, Aluminium, and Oxygen.
• Strontium Aluminate molecules vary in complexity, with the exact molecular composition determining the colour it emits.
• There are various blues that can be made by varying the Strontium Aluminate molecule composition, but this one is by far the brightest.
• This is pure Strontium Aluminate, so this really is as bright as it gets. We don't dilute it at all.
• The size of the particles also has a large impact on the brightness of the glow (the bigger, the brighter), so depending on what you're using it for, you can make sure you have the brightest possible option.
