Professional Gold, Silver, Platinum Jewelry Testing Kit with Stone Instructions and Box with 30X Eye Loupe Magnifier Precious Metals 10K 14K 18K 24K 999 925 Scrap

This metal testing kit comes with everything you need to verify the type and quality of metal you're looking at. In addition to this kit, you will need safety goggles, rubber gloves, and baking soda, in order to use it safely.The kit comes in an intricately compartmented wooden box. Most of the compartments are small and designed to hold your various acids and chemicals closely. It comes with a 30x jeweler's loupe and a scratch stone with a non-slip surface on the back.There is an included instruction booklet, but the procedure is very easy; scratch your metal item on the stone, back and forth a few times, in a spot that won't show the scratch. Really, the scratch is very minor; I couldn't see it without the loupe after I did it. But still, try to pick a spot in the back of the piece if you can. Next, apply your clearly marked, appropriate acid from the kit. Repeat if necessary (there are several formulas for testing gold). The instruction booklet will help you interpret positive or negative results based on whether or not the line dissolves fully, partially, or not at all. Then, carefully clean the stone with a solution of baking soda (to neutralize the acid) and water, dry, and put it away for next time. Easy and fun! It works great, and it takes longer to set up for the test than it does to do the actual test, which is pretty typical for sciencey things.My only complaint is, I wish the box had a poison sticker or brand on it, because something about the plain wooden box attracts people to it. They make a bee-line for it and open it without asking. I'll have to make my own sticker or mark, although that might make people even MORE curious. Anyway, that doesn't effect the quality or the accuracy of the kit, it's still a 10/10 for quality, accuracy, ease of use, and a really well-made storage box.

Justo lo q esperaba los acidos para poder probar las prendas

Although I haven't tried this yet, I believe it will work fine. Whether it does or not, I will try it on several metal objects , and will then submit a revised evaluation.
