[QUOTE="Brumble-Gum, post: 214964, member: 1569"] Not nuggets but any specimens that have [u]most or all[/u] of the gold inside, I pop into Alibrite for a few months. I use a beetroot tuperware container with the sieve/basket inside its easy to lift up and see how the digestion process is going. In a well ventilated area, always use chemical rubber gloves and clear safety glasses at all times, wash your hands and arms after. [b]**** Do not use a glass containers to hold Alibrite as glass is made from silica and will eventually be eaten through by the acid[/b]. Its an Aluminum mag wheel cleaner from Supercheap Auto. Once the gold has been released from inside the rock I transfer to another container (Non silica) and heap bicarb soda with water onto whatever remains for two days. then you simply flood with water for 10 minutes. Then after months of waiting you can see what your gold looks like from inside the specimen. Any specimens that I find that have the gold already showing I keep instead of popping into an acid bath. These look good and shouldn't be destroyed. Please be safe when playing with any acids if in doubt , scrub or wash your self. Alibrite contains Hydroflouric acid this dissolves calcium and silica to get the gold out of the specimen. When applied to the human body it dissolves the calcium in your bones making them brittle and easily broken. A course of calcium injections for the rest of your life doesn't sound good. So play safe with all acids. [/QUOTE]
