<p>[QUOTE=&quot;desertgem, post: 779583, member: 15199&quot;]The majority of patents issued for non-tarnishing silver ( mainly for medical uses) consist of 92% silver, 4% indium and 4% titanium ( or similar alloying) . It would be a small thing to make the silver content 92.5 or above to qualify for sterling for consumer silver. These patents go back almost 30 years, but there is a huge time difference from getting a patent and producing a commercial product. I don&#039;t think the refiners would care to deal with this silver. And the higher the silver level, the less tarnish resistance.</p><p><br /></p><p>The newest advances are in the area of silver-carbon fiber and silver ceramic composites., which also are non-tarnishing . </p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
