<p>[QUOTE=&quot;2manybooks, post: 2719593, member: 8267&quot;]Which is what I have said - absence of easily visible schreger lines does not mean an object is not ivory, but if you do see them it is a positive indicator of ivory. For those who can see them it is an easy way to confirm an object is ivory.</p><p><br /></p><p>This is a card case that [USER=63]@cxgirl[/USER] recently posted here. Faint schreger lines are visible on the edge of the small panel in the center:</p><p><img src="https://www.antiquers.com/attachments/ivory-card-case-jpeg.275181/" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><a href="https://www.antiquers.com/threads/card-case-ivory.53414/#post-2707597" class="internalLink ProxyLink" data-proxy-href="https://www.antiquers.com/threads/card-case-ivory.53414/#post-2707597">https://www.antiquers.com/threads/card-case-ivory.53414/#post-2707597</a></p><p><br /></p><p><br /></p><p>I don&#039;t know why you cannot see them on a cross section of genuine ivory, unless perhaps it has been bleached as [USER=1496]@Hollyblue[/USER] has suggested. If you cannot see them on a cross section, the conclusion should be that you are not looking closely enough, the ivory has been treated to minimize their appearance, or your object may not be elephant ivory. </p><p><br /></p><p>Unless you have a unique source of mutant elephants, the structures that appear as schreger lines are present in all genuine elephant tusks, whether you can see them or not. This is not just my opinion. While I have handled a great many ivory objects, I have also studied the scientific literature on the physical structure of natural materials. Have you read the article I provided a link to? I can provide more if you want to explore the topic further.[/QUOTE]</p><p><br /></p>
