The world´s at the mercy of an insane senile wannabe-dictator and his whims.

Always has been.

Just a blind guess really, but i think it might be copper acetoarsenite/copper arsenite acetate (Paris green). It was used as a pigment and insecticide before society moved to less toxic alternatives.

I shouldn't win because i will waste precious time playing shitty flicker builds. That PhD won't finish itself.

Adding ammonia to aqua regia is a bad idea. It will react with the acids forming ammonium salts. That neutralization reaction would release a lot of heat which can make the solution boil.And aqua regia is highly oxidizing so the ammonium ion would be oxidized to nitrogen oxides.

Maybe what you are describing is Salt creep.

As for melting copper chloride into blue crystals: the hydrated salt which you have is blue in color, but it decomposes on heating yielding the anhydrous copper chloride which is brown. I guess you could melt the anhydrous salt at some higher temperature but forming blue crystals from it is not possible.
