JSPNitric Acid Substitute 16 Ounces

I used this stuff to etch some gold coins. Worked great. Made the coins look much better and they were graded, with a score, so i achieved my goal. Thanks!

"Effective Nitric Acid Substitute for Gold and Silver Refining!"

Need it in a liquid works better

It's not what I thought it was ... but it's OK

Product didn't work was week lost gold because of that and didn't dissolve according to instruction.

Arrived fast, as advertised, great price

I followed the instructions to a tee, with very weak nitric acid results. Ran it 4 times and not one batch was worth saving

Has a extensive process to make nitric acid from this substitute....just get nitric acid...Walmart online sells it cheapest I've found for small amounts
