Bark Tanning Skins into Leather for Taxidermy – A Sustainable, Natural and Non-harmful Alternative to Commercial Tanning Products?

Written by Jazmine Miles Long, Taxidermist.

When a taxidermy mount is made, the skin of the mammal (and in some cases reptiles and birds) is usually tanned. Tanning is the process of turning a raw skin into leather using chemistry. By turning the skin into leather, we are changing a fragile perusable material into something durable that can be sculpted into taxidermy and be more resistant to insect attack. Tanning the skin involves removing proteins in the skin and loosening the collagen fibres and then attaching tannins to these structures. Leather can be made with either the hair on or off the skin. When we are making taxidermy, we want the fur to stay attached to the skin and so the process is different to when the fur is to be removed. With hair on tanning, we want the pH to stay low to prevent the fur from falling out. The skin starts by going into a pickle solution of around pH 2 and after it has been through the tanning process it ends up at about pH 4.5 -5.

A Hundred Feet Through the Door – A Chance Encounter with some Centipedes set me on a Curatorial Path…

Written by Dan Gordon, Keeper of Biology, The Great North Museum: Hancock.

So, how did I get started in museums? Like perhaps many people, it began with a stroke of luck.

I’d decided to study Biology at university—I suppose I’d vaguely pictured myself at some point in the future, white-coated in the lab, pouring over spectrophotometer readings or agar plates. But by the end of the first year, I found myself staring out of the window during practicals. Nineteen-year-old me was slowly becoming disillusioned: Botany was biochemistry; Zoology was elegant mathematics; even Ecology was really an intricate forest of statistics, not trees. There was beauty in the numbers, but it was all a long way from my childhood passion for birdwatching, rock pooling and reading travel books. One day, peering at smudges on a petri dish and trying to work out if I’d just induced gene expression, I realised I might not be cut out for that imagined future. I was fascinated by the soul of the subject, but the finer points of its language were losing their magic.

5 Top Tips on How to Decant your Museum

By Eimear Ashe, Collections Moves Project Manager, National Museum of Ireland

Having recently completed a major decant of Natural History collections in the National Museum of Ireland, I thought it a perfect opportunity to share my learnings with fellow NatSCA colleagues.

National Museum of Ireland – Natural History

Tip 1. Start with the staff!

  • What skills do you need to recruit in or increase capacity in?
  • Recruit new temporary staff. Training should be provided in the following areas: hazards in collections, manual handling, object handling, photography (if part of the workflow), condition assessment, object packing, transfer documentation procedures, integrated pest management (IPM), and the collections management system.
  • If you cannot recruit new staff, you will have to use existing resources. Agree with management that the permanent staff team will not be able to carry on their regular duties during the period of decant. You should also make the public aware of this reduction in capacity and service provision.
