<p>[QUOTE=&quot;2manybooks, post: 4413960, member: 8267&quot;]The diagnostic schreger lines cross-hatching of elephant ivory are most visible on cross sections, or at least curved areas, of the original tusk. They will be much less apparent, or even invisible, on thin flat sections cut along the length of the tusk (a tangential section), such as these fan sticks, or piano keys. What might be visible are faint nested cone shapes, or a sort of &quot;watered&quot; effect.</p><p><br /></p><p>Here are piano keys, which traditionally used elephant ivory. (The lighter keys in this view are modern ivory alternatives. The yellower ones are genuine ivory.)</p><p><img src="http://www.squarepianotech.com/wp-content/uploads/2011/03/C-and-E.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
