leaf is far from cheap. Sell the coins. get 24 karat fine shot. The copper simply contaminates the process and tends to make a color much like like nice motor oil. You need both hydrochloric and nitric to make aqua regia and you can write me privately as to how to use it and what amounts to add to silica to make the sands.

You will get this great stuff and it will run a bit over a buck a pound to get intense color rod. This is for my class students. The hard part is getting the lead.
