<p>[QUOTE=&quot;Bronwen, post: 3543248, member: 5833&quot;]Thank you, Holly.&nbsp; The article is riddled with inaccuracies, but the photo of ultrasonically worked shell is very interesting.&nbsp; I&#039;m not home at the moment, but want to check the Miller book to see if this is quite correct: &quot;In her 1991 book, “<a href="https://amzn.to/2W3H05r" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://amzn.to/2W3H05r" rel="nofollow">Cameos: Old &amp; New</a>,” Anna M. Miller wrote that at that time it was estimated that as many as eighty-percent of cameos were being machine-cut by ultrasound in Germany and Japan.&quot;&nbsp; The German cameos would be the hardstone ones.[/QUOTE]</p><p><br /></p>
