Q. How long does it take to dissolve away the impurities of a, say, heavy 14k gents ring?
If you simply drop the entire ring into nitric, it's going to take a long time for anything to happen as the outer gold content will resist the acid
and not allow it to penetrate.
Instead, I'd cut the ring up into many small pieces which will then give the acid a much gretaed surface area to attack and consequently speed up the
dissolution of any silver, copper, etc.
Q#2, have you encountered gold+platinum alloys, yet? Platinum tends to 'take over' if you remelt an alloy containing the two (found in some high-end
white gold alloys).
No, most of the "raw" material I use has been obtained from gold nuggets so platinum contamination hasn't been an issue for me.
Last question / point = now what?
If you sell it, it still has to be assayed and while your investment is raising in price, you will still have to sell it at a discount.
All the gold (and silver) that I process is for personal LONG-TERM investment purposes e.g, 2, 5 or even more years. By the time I do get around to
selling any of it, hopefully it will have increased in value sufficiently to allow a slight loss due to "discounting".
Also, selling on eBay always seems to find a buyer willing to pay at, and occasionally slightly above the going market rates.
