A Refresher Course on Fluid Specimen Conservation at the Natural History Museum of Denmark

Written by Anastasia van Gaver (Conservator) & Bethany Palumbo (Head of Conservation) Natural History Museum Denmark).

Workshop participants and Julian Carter

As conservators, it’s essential we keep up to date with developments in the techniques used in specimen treatments. With hundreds of fluid-preserved specimens to make and conserve for the new exhibitions at the Natural History Museum of Denmark, we sought the best in the field to give us a refresher course. Esteemed expert Julian Carter arrived fresh off the plane from Cardiff and over 3 days we explored different techniques for preserving and mounting specimens and well as discussing the unique challenges we face when conserving these invaluable scientific resources.

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.

30th Symposium on Palaeontological Preparation and Conservation: Call for abstracts

Please send abstracts of up to 250 words plus an image to sppc@geocurator.org by 10th April. Abstracts will be considered on any topic of earth science excavation, conservation, preparation mount-making and exhibition. Please state if the abstract is for a poster or platform presentation.

The 30th Symposium on Palaeontological Preparation and Conservation will be held in the Netherlands this year on 26 – 27th June.

The theme will be ‘From Excavation to Exhibition’ and they hope to broaden their usual remit to include more aspects of the story of how geological collections end up on display in our museums, as well as their conservation and preparation.
