apparently copper chloride is the one to use for the best blue.
what i want to do is soak my wicks (Kevlar) in a liquid version it, let them dry so the copper chloride is then a solid, theoretically a powder, throughout the weave of the wick which can then be lit and burn blue. The wicks are for a fire staff, they are 63mm wide, 200mm long and 4mm thick. So not your average candle wick.
Would this work?
If so how do I make the copper chloride? or is there another substance that would be more appropriate?
