I figured I would ask this here because well........ you guys find a ton of gold. 
I am looking to get a gold test kit. I see kits that test for various k's have a different bottle of acid for each. How does that all work? If you use a 10k bottle on 14k what happens? And vice versa if you use a 18k bottle on 10k? Is there anything I should look for. How do you actually use the kit? And last has anyone purchased a kit that they like?
Thanks!
