Hi Danny: On sterling silver (92.5%) I use 1.0 milliliter of nitric for 1.0 gram of pure silver and 3.5 ml of nitric for each gram of other metal like copper and etc. (GSP formula) So on 10 grams of sterling at 92.5% silver, I would use 12.0 ml of nitric acid and 12.0 ml of distilled water. Bring it to about 150 to 175 degrees F. and it should totally dissolve in about 5 to 10 …
Both cause a chemical reaction that disintegrates the alloys in the jewelry over time. (Nearly all gold jewelry is alloyed, because pure gold is too soft on its own.) One study showed that when a 14K white gold ring was placed in common bleach for 36 hours, the ring completely disintegrated! Small amounts of chlorine exist in tap ...

after that much material has been run through such a low volume of solution im surprised your getting any reaction at all,especially without a fish bubbler.your solution is loaded with tin, it probably has been to the saturation point a few times. as you add H2O2 it also dilutes the acid somewhat and allows tin to precipitate out as a white crystal.when you start back …
Using only the HCl acid (muratic) will normally breakdown the rock/silca which encases the gold. but HCl is also used to remove/dissolve the base metals associated with …
