My experience, however, was so positive with these.
It is very important to use the acid If you get it on your fingers, it will destroy them. The first thing you need is a touchstone if you do not already own one. When you scratch the material to be tested on the slate stone, you will get a dark grey speck. Once on the mark left on the stone, you drop a single drop of acid. It indicates a negative reaction to whatever acid you used by not disappearing the mark. be careful so children and adults who are immature do not come into contact with the acids. I wish you the best of
That was not the case with mine. If you could give me instructions on how to test one piece with a 10-foot model What if 22kt and Silver scratched and then did not disappear?

The product was good and the price was good.
An excellent set of tests.
In accordance with the advertisement.
I've always found JSP's products to be on top of the game. The Xenon 40D does the job admirably. If you don't have a fancy xenon 40D, then this is the one for you Metals can be tested using a ray machine.
The product works for me. I am satisfied with the product. I would like to thank the.
In my opinion, it would be nice if there was more 14 karat gold test acid in there. A complimentary bottle would be nice.
My quest for what I wanted.
For the price, this is a good set of acids. Each of the chems works as required. There is no stone that comes with it, and that is kind of disappointing.
