<p>[QUOTE=&quot;DragonflyWink, post: 2350574, member: 111&quot;]Positively determining whether an unmarked piece is silver or not from images online can only be an educated guess, but will offer some thoughts:&nbsp; </p><p><br /></p><p>Regarding the form, though not necessarily what it is, it looks very much like a fairly plain English pint tankard, and would more typically be silverplate or pewter, but they were also produced in silver - quick search doesn&#039;t find any with a reinforced lip like yours (kind of reminds of the brass lip sometimes found on pewter tankards).</p><p><br /></p><p>Regarding the &#039;ice test&#039;, have used it and silver does chill very fast, but I&#039;ve only used it for spoons, with a known silver and/or silverplate spoon of very similar thickness and length for comparison (a friend calls it the &#039;ice cream test&#039;, and just sticks the spoons in ice cream) - the silver will chill much faster, but should be kept in mind that nickel silver is not just nickel, it is typically at least 60% copper, and it will conduct the temperature fairly well too, though at a slower rate.&nbsp; Not going to take the time to search for a chart like Nate&#039;s that includes nickel silver, but this page mentions that it &quot;possesses high thermal and electrical conductivity&quot;: <a href="http://www.nealloys.com/cupro_nickel.php" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.nealloys.com/cupro_nickel.php" rel="nofollow">http://www.nealloys.com/cupro_nickel.php</a>&nbsp; I&#039;m no scientist, and honestly don&#039;t know the effectiveness of an ice cube test without a comparison object. </p><p><br /></p><p>The pics are not particularly clear on my screen - does the bottom show soldering, could it have been replaced?</p><p><br /></p><p>This page linked below shows a number of sterling pint tankards, similar in style, size, and even weight in some (you might also measure its capacity, keeping in mind that Imperial pints differ from American) - I&#039;m not stating an opinion on the origin or material, but if mine, an XRF test would be in order...</p><p><br /></p><p><a href="https://www.bryandouglas.co.uk/silverware/tankards/tankards.htm" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.bryandouglas.co.uk/silverware/tankards/tankards.htm" rel="nofollow">https://www.bryandouglas.co.uk/silverware/tankards/tankards.htm</a></p><p><br /></p><p>~Cheryl[/QUOTE]</p><p><br /></p>
