I'm wondering what is the best process after a 50/50 nitric acid soak.
I have Gold Filled jewelry that I am refining. I put about 5 ounces in my beaker. After about 3 days and 800 ml of 50/50 nitric acid(pouring off after each 200 ml) I am wondering how to proceed without impeding my future process. I normally let each 200 ml HNO3 sit on a hot plate for 4-8 hours. I will eventually put my GF lot into aqua regia.
I'm not trying to sound stupid, just looking for advice. I have already washed twice with hot water. Should I proceed to wash with ammonia? I am looking for an efficient way to get to the point where I can put my lot into aqua regia. After I washed with hot water, how long should I let it set before I pour it off? I have been waiting about 4 hours. Is this too long or too short? Hoke doesn't really say much about time frames, so I'm wondering if you have any advice.
After the 3 days of HNO3 soak, I pulled a watch case out and tested it, came up at 10K, so should I soak the lot in more HNO3? Or go right to AR?
Thanks for any advice and time you can give me!
