<p>[QUOTE=&quot;Joan, post: 9574055, member: 5398&quot;]I&#039;ve been trying to test some unmarked and marked silver jewelry that I&#039;ve had for years...trying to label things for future selling. </p><p><br /></p><p>A few days ago I posted photos of a necklace that I thought might be platinum because it&#039;s heavier than sterling, and [USER=81222]@Kaiserpoo[/USER] translated the Chinese marks and included a link to the probable maker in Hong Kong. It tested positive for platinum, but I was using old platinum testing solution and was told old solutions lose their effectiveness, so I ordered a new bottle. However, when I tested it with the new platinum solution, the scrapings dissolved. So I took it to a jeweler who used an electronic tester which showed the necklace is solid platinum (she also did a teeny scrape on one of the links (which she later polished out) to make sure it wasn&#039;t plated, which it wasn&#039;t). </p><p><br /></p><p>Anyway I did more research on testing solutions to figure out why my old platinum solution seemed to work and the new solution didn&#039;t. Somewhere I read that the acid can last for years if it&#039;s not used much and is kept tightly sealed. This was the first time I had used my old platinum acid.&nbsp;&nbsp; </p><p><br /></p><p>I also read reviews on the various Amazon sellers of the testing solutions, and several buyers complained that the solutions they ordered were old and not usable. <b>So I&#039;m wondering if my new platinum solution is outdated and I should ask for a refund</b>.</p><p><br /></p><p>I&#039;m also having difficulty interpreting results with new silver testing solution that just arrived today. When I tried it with a marked sterling silver piece of jewelry, it seemed difficult to distinguish whether the scrapings turned dark red (.925) or brown (.800) as shown in the instruction booklet. I also tried it with a few other pieces of sterling jewelry and had a hard time seeing a red color under the acid bubble.</p><p>[ATTACH=full]460623[/ATTACH] </p><p><br /></p><p>I decided to try the same piece of sterling jewelry using brand new 18K test solution and also my old 18K solution (which I&#039;ve only used a few times). Here&#039;s what happened.</p><p>[ATTACH=full]460624[/ATTACH] </p><p>So I&#039;m thinking I should ask for a refund on the new 18k solution also--I bought it from a different seller than the platinum solution that doesn&#039;t work. Has anyone else had problems like this with metal testing solutions?[/QUOTE]</p><p><br /></p>
