<p>[QUOTE=&quot;Plumbata, post: 3226806, member: 96864&quot;]I&#039;m not really sure, but the appearance of acid-etched modern silver is significantly more &quot;frosty&quot; and fine-grained than the appearance of ancient crystallized silver, which is much more coarse and fissured in appearance to both the naked eye and under magnification. My understanding is that the crystallization of silver is an extremely slow process and takes centuries, but perhaps it can be replicated by repeated heating and cooling to encourage the copper atoms to migrate, followed by chemical treatment? That&#039;s a question for a metallurgical expert.[/QUOTE]</p><p><br /></p>
