I think I found a nitric acid legally

Ok, so there WILL be a few issues, BUT food for thought.

I was testing my Silver and the active ingredient was nitric acid. I looked at some gold testing solutions and again Nitric acid

EXPENSIVE but it could finish a small batch???

Thoughts

If that is your only option, I would find a less expensive hobby.

I know, it was just food for thought.

No Nitric acid sadly. I just had a thought and decided to share it. Still doing research and popping in every now and then to see if anyone has found a solution to this issue.
