Kit contains 1/2lb pack of nitric acid substitute to be mixed with hydrochloric acid. This is used to dissolve gold for later precipitation. 1/2 lb 99% pure prilled Urea, pH balancer. Used in precious metal refining with aqua regia. Added to the filtered solution to balance pH. 1/2 lb gold precipitant (SMB) Odorless and non-toxic, with an unlimited shelf life. It precipitates in heavy, shiny, flake form, making rinsing and decanting much easier and faster, avoiding inadvertent losses of gold during rinsing. Precipitates gold of at least 99.95%+ purity. Stannous Chloride, gold/silver/platinum detector. Premixed liquid. An absolute necessity to make sure you have dropped all the gold from your aqua regia solution before you discard it.
