Aqua Regia is not a suppressed technology secret. It is commonly used and
well known by anyone working with precious metals. It is mixed using 3
parts HCl to one part H2No3. It is not something you want to be playing
around with unless you follow safety precautions. It degrades fairly
quickly as the nitric evolves as an orange/brown vapor. HCl by itself
dissolves silver very quickly. In both cases adding some heat speeds up the
process. You do not want to be breathing the vapors from any dissolution of
metal.
