<p>[QUOTE=&quot;2manybooks, post: 4490961, member: 8267&quot;]It can be quite difficult to confirm ivory when it is intricately carved. You need to find flat surfaces, large enough and in the right orientation, to see the uniquely diagnostic &quot;Schreger&quot; lines. (Schreger lines are subtle, spiraling and intersecting lines, which are fine tubules that carry nutrients during the growth of the tusk.) If you cannot find Schreger lines, it does not necessarily prove that an object is not ivory, as they are sometimes difficult to see. But if you do see them, it is the best evidence that an object is indeed ivory.</p><p><br /></p><p>Here are some resources that describe how to identify ivory and similar materials:</p><p><a href="https://www.antiquers.com/threads/ivory-references.69023/" class="internalLink ProxyLink" data-proxy-href="https://www.antiquers.com/threads/ivory-references.69023/">https://www.antiquers.com/threads/ivory-references.69023/</a>[/QUOTE]</p><p><br /></p>
