Copper benzoate is poisonous and should be handled wearing a dust mask
$20.00 PER POUND
Copper benzoate is used in pyrotechnics to create a blue flame. This is desirable because the blue spectrum is often difficult to achieve and a good blue star is the mark of an accomplished pyro. The formula for copper benzoate blue is 82/18 Ammonium Perchlorate/Copper Benzoate. It is not used very often as it is more expensive than most alternatives.
