<p>[QUOTE=&quot;Jeff Drum, post: 453995, member: 6444&quot;]Hard for me to know since I dont know what technique you used or how you did the math, but if your website was reliable and showed how to do the math then that should be right.</p><p><br /></p><p>And those values do suggest “German silver” or similar tin/copper based alloy. I always test a known piece of sterling and silver-plate along with the pieces I need to test. That way I can be sure I’m not screwing up somehow. There are other tables of specific gravity online, this one shows German silver at 8.58 and pure silver at 10.5 (the spec gravity of sterling and other non-100 percent mixes will be somewhat lower than 10.5 due to the mixed in copper etc but still higher than 10). <a href="https://www.engineeringtoolbox.com/specific-gravity-solids-metals-d_293.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.engineeringtoolbox.com/specific-gravity-solids-metals-d_293.html" rel="nofollow">https://www.engineeringtoolbox.com/specific-gravity-solids-metals-d_293.html</a>[/QUOTE]</p><p><br /></p>
