How to extend glow time?

Question asked by Sami Malik on Apr 4, 2014

Hi every one

 

I have a question that i hope you can

help me with, i bought some glow powder

in different colors and have to mix i with paint

but when its fully charged, it then only glows

for 1 hour after sunset, it has to glow for a whole night.

 

My question is, if there is a material that i can add,

so that the glow time is much longer ???

 

With Friendly Greetings
