<p>[QUOTE=&quot;2manybooks, post: 4505460, member: 8267&quot;]From a previous discussion about rhino vs cow horn on the forum:</p><p><br /></p><p>&quot;Cattle horns grow over a bone core, in a series of nesting cones. They are hollow for most of their length, with just a small portion of solid material at the tip. Inside, at the center of the tip, there is an &quot;eye&quot; pattern created by the overlapping series of cones. The walls of cattle and bison horns are relatively thin, as support is provided by the bony core. The base of the horn tends to have a smooth circumference, round, or elliptical, or triangular, but not wavy and irregular.</p><p><br /></p><p>Rhinoceros horns do not grow over a bone core. Rather, they grow like bundles of hair fibers extending upward from the skin surface. There is only a shallow hollow at the base of the horn. This would be enlarged by carving for the traditional use as a drinking cup. Because of this hair-like structure, a cross section of Rhino horn will not show patterns of growth rings like the stacked cones of cow horns. Instead, under sufficient magnification, it will show a collection of tubes. These tubes are about .5mm in diameter, hence the need for significant magnification.</p><p><img src="http://www.vikingsword.com/vb/attachment.php?s=aa65b6f060ae831a5dac92c66c573314&amp;attachmentid=28204&amp;stc=1" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><a href="https://www.antiquers.com/threads/carved-horn-2.50906/#post-2313069" class="internalLink ProxyLink" data-proxy-href="https://www.antiquers.com/threads/carved-horn-2.50906/#post-2313069">https://www.antiquers.com/threads/carved-horn-2.50906/#post-2313069</a></p><p><br /></p><p>When reviewing information on rhino horn, I came across an article describing a potential method of making fake rhinoceros horn from horse hair. An abstract of the article describes the process:</p><p><br /></p><p>&quot;Demand for rhino horn is driving poaching with devastating effect for the few individuals left of the few species surviving from this once numerous, widespread and cosmopolitan clade of pachyderms. We bundled together tail hairs of the rhino’s ubiquitous near relative, the horse, to be glued together with a bespoke matrix of regenerated silk mimicking the collagenous component of the real horn. This approach allowed us to fabricate composite structures that were confusingly similar to real rhino horn in look, feel and properties. Spectral and thermal FT-IR, DSC and TGA analysis demonstrated the similar chemical composition and thermo-mechanical properties between the natural and the faux horns.&quot;</p><p><br /></p><p>And you can read the whole article here:</p><p><a href="https://www.nature.com/articles/s41598-019-52527-5" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.nature.com/articles/s41598-019-52527-5" rel="nofollow">https://www.nature.com/articles/s41598-019-52527-5</a> </p><p><br /></p><p>The cup that [USER=77128]@gouldcx[/USER] has posted does have features that look like rhinoceros horn, particularly the fibrous texture. But if you look at all of the photos on the ebay listing that [USER=20118]@LauraGarnet02[/USER] linked to, the carving and texts appear to be identical (unless they are in fact the same cup). They look like they might have been pressed in a mold.</p><p><br /></p><p>If you search for &quot;horn libation cup&quot; on ebay, you will see many types of &quot;ox horn&quot; cups coming out of China. Some make the effort to more closely mimic the shape of rhinoceros horn, in addition to the fibrous texture. But they appear to be mass produced.

But they are probably making a tidy profit, and will fool some people into thinking they are buying a much more valuable object. Yet another type of fake to be wary of.[/QUOTE]</p><p><br /></p>
