[Nhcoll-l] Covering for large hooks

[Gali Beiner]

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?

Some varieties may be chlorinated, though, so the product type will have to
be carefully checked.
