i see colored motors all the time now..."green gorilla" "red line" ...etc...are these motors using the traditional coloring agents? such as barrium for green and strontium for red? or are they also using composite coloring agents?
As far as I know, Copper Oxide is not used in Blue Thunder Propellant, Copper Chromate is. Most Copper Oxide formulations have Aluminum in them to increase the brightness of the blue, but this increases smoke.Originally posted by bjmcder
Faster propellants like "blue thunder" have a small percentage of copper oxide to increase the burn rate, and the copper also produces the blue color.
