Wondering if there is a process to purify barium sulfate. I have access to 1000 gm that has a slight amber hue to it. It dose not perform well in strobe propellant. I switched it with synthesized barium sulfate (white) in the same comp and everything worked fine.
The product was purchased from a pigment supplier. I suspect it is of the mineral type accompanied with some sort of impurities?
I believe there must be an easy way to purify it rather going through the laborious route to synthesize it.
