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.

Planet Ocean: Using Local Collections to Celebrate Global Climate Action

Written by Sarah Marden, Curator of Natural History at The Box, Plymouth.

From March 2024 to April 2025, a new exhibition at The Box called Planet Ocean explored Plymouth’s marine heritage and contemporary identity as “Britain’s Ocean City”. Specimens from our natural history collections, including spirit-preserved marine invertebrates, molluscs, corals, mounted sea birds and seaweed folios were displayed alongside art, world cultures collections, image and film and loan material from local partners.

Taking inspiration from science fiction writer and undersea explorer Arthur C Clarke who said “how inappropriate to call this planet Earth when it is clearly ocean”, we explored why the ocean is so important- the fact that we literally couldn’t survive without it as it gives us around half the oxygen we breathe, but also that it sustains and supports us locally with food, jobs, leisure, health and wellbeing. Alongside this quote, the entrance wall of the exhibition featured a moving graphic created collaboratively with Plymouth Marine Laboratory. It used one of the oldest datasets in existence of changing ocean temperatures recorded in Plymouth Sound. This data was input into a globe representing our ocean planet that changed and distorted according to the human impact of climate change over time. This was the first example of science meeting art and partnerships that we developed throughout the exhibition.

A Time Capsule of Extinction: Scotland’s Iconic Wildlife

Written by Caitlin Jamison, Museum Collection Technician, Montrose Museum: ANGUSalive.

Montrose Museum in Angus, northeast Scotland, houses an impressive natural history collection. Everything from taxidermy to fossils to rare minerals are housed in a modest, Greek-revival style museum off the high street. Built in 1842, it is one of the first purpose-built museums in Scotland.

Sadly, due to changing public interest (and the challenging funding situation facing many local authority museums) the collection has been somewhat forgotten since it was catalogued onto neat pink index cards in the late 1970s.

New Unnatural History Museum Sessions

The Unnatural History Museum brings together museum professionals, creatives and academics across disciplines to platform vital conversations about the museum mediation of the natural world during the sixth mass extinction. The series unfolds over a series of themed Zoom sessions featuring short presentations, followed by a roundtable discussion.

Links to upcoming sessions can be found here: https://www.eventbrite.ie/o/verity-burke-53923741293 and will continue to be updated as more events are added.

The event series now has a website where recordings of prior sessions will be uploaded and you can check out upcoming events: https://unnaturalhistorymuseum.org/

Packing the Blaschka Glass Models 

Written by Julian Carter, Principal Conservator Natural Sciences, Amgueddfa Cymru – Museum Wales, Cardiff

During the late 19th century, Leopold Blaschka (1822-1895) and his son Rudolf (1857-1929) produced thousands of beautifully detailed glass models of a wide range of sea creatures, and other animals, for natural history museums and aquaria all over the world. The work has since been hailed as “an artistic marvel in the field of science and a scientific marvel in the field of art”. The work of the Blaschka’s remains remarkably contemporary today, working as they did on the cusp of design, craft, and industry. Crossing the boundaries of science and art, the surviving models today have a value that makes them irreplaceable. 

The idea for making lifelike renditions of sea creatures out of glass arose from the difficulty of preserving and displaying soft-bodied animals such as jellyfish, marine worms, and sea anemones. Preserving such animals in a lifelike way is difficult as techniques such as fluid preservation cause colours to quickly fade and shapes to become distorted. Leopold Blaschka devised a solution to this problem by using his glass working skills to accurately model these animals out of glass and other materials available to him and went on to establish a successful business supplying glass models to museums worldwide during the latter half of the 19th century.
