<div dir="auto"><div>Several years back, in my post as conservator at the Pitt Rivers Museum in Oxford, I was very interested to learn that the mountmakers used polyethylene powder to create coatings for metal hooks. That was a while back and I don't know if this is still done today, but actually this is an option I want to check for some mounting I will have to create soon. The idea was that polyethylene powder wasn't all that different from all the other polyethylene products used in conservation and since it only needed heat to turn liquid and coat the metal this was preferable to other products. I'm not familiar with Plasti Dip, and gather that is a generic commercial product with unknown components (will be happy to learn more if possible) . Maybe it is better to seek out polyethylene powder? </div><div dir="auto"><br></div><div dir="auto">Some varieties may be chlorinated, though, so the product type will have to be carefully checked. </div><div dir="auto"><br></div><div dir="auto"><br><div data-smartmail="gmail_signature" dir="auto">Gali Beiner (ACR)<br>Conservator, Palaeontology Lab<br>National Natural History Collections<br>The Hebrew University of Jerusalem <br>Berman Building, Edmond J.

<p class="MsoNormal">Greetings all,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am looking for an option to cover these large hooks that will be holding Mammoth tusks. I suggested some polyvinyl tubing, but the cabinet shop wants to “dip” them in plasti dip. Does anyone have an archival medium suggestion that
won’t damage the potentially friable outer layer of these tusks? The hooks are 1.25 inches in diameter.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Thanks for any ideas!<u></u><u></u></p>
