<p>[QUOTE=&quot;Oldhoopster, post: 4471287, member: 84179&quot;]The ice test depends on the thermal conductivity of the metal/alloy.&nbsp; It may give you some indirect information, but I would not call it a conclusive test.&nbsp; If you do it side by side with some known metals, then you might be able to say if the thermal conductivity is higher or lower than the known sample.</p><p><br /></p><p>Testing for specific gravity should tell you a lot more.</p><p><br /></p><p>BTW. If you&#039;re not locked down, find a local coin shop, jeweler, or &quot;we buy gold&quot; place with a handheld XRF.&nbsp; That should give you a good answer as long as it doesn&#039;t have a thick plating (and a specific gravity test will confirm if it&#039;s plated or not)[/QUOTE]</p><p><br /></p>
