A Mammoth Task: Stabilising and Protecting Fossil Mammal Specimens in a Sustainable and Access-friendly Way for a Large-scale Collections Move.

Written by Lydia Amies, Caitlin Jenkins, Emanuele Casafredda, Lucia Petrera, Tanya Nakamoto and Fabiana Portoni, Natural History Museum, London.

The Natural History Museum, London (NHM) is moving a third of its collection (28 million) specimens to a to a new, purpose-built centre at Thames Valley Science Park near Reading. Under the umbrella of the Unlocked Programme a new facility is being designed and built to house natural history specimens, research laboratories, working space, and digitisation facilities. The project started in 2020 and the moves stage will commence in 2028.

The Unlocked Conservation Team is working to assess, treat and stabilise at-risk specimens that are due to move. Our focus is to futureproof collection storage while using materials in a sustainable and cost-effective way. Our work will improve access to the collections and enable safe handling of specimens. One of the largest and most complex collections we are working on is the Fossil Mammal Collection which is made up of a wide variety of species, from tiny extinct rodents to woolly mammoths.

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.

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.

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.

It’s Getting Better

Written by Dr Amy Geraghty, Assistant Keeper/Curator of aquatic zoology collections with responsibility for fluid collection management.

The National Museum of Ireland (NMI) Natural History Division (NHD) holds about 2 million specimens in its collection. The collection is ordinarily split between three locations: the museum and two off-site storage buildings. However, at the time of writing, nearly all specimens are in one of the two storage buildings. The museum galleries are being emptied to facilitate investigative works on and the refurbishment of building itself.

One of the storage buildings is a mid-nineteenth century British army barracks that came to NMI in the mid-1990s and now stores NHD collections. Retrofitting the building for collection storage has involved the installation of plasterboard ceilings, internal doors, and security and fire alarm systems. Toilets, telephones, a tearoom, shelving, and internet facilities were later installed in the 2000s.

Snagged Setae 2, The Sequel: Packing Materials After 14 Years in Fluid Storage

By Lu Allington-Jones (Senior Conservator), Wren Montgomery (FTIR Specialist) and Emma Sherlock (Senior Curator), The Natural History Museum, London UK

Many years ago, we undertook some research into a suitable replacement for cotton wool as bungs for vials holding small fluid-stored specimens. In 2008 we placed samples of Parafilm MTM, white Plastazote® LD45 and colourless HDPE (high-density polypropylene) lids in 10% formalin, 100% ethanol, and 80% IMS (Industrial Methylated Spirit, aka Industrial Denatured Alcohol) and allowed them to steep for 3 years. We undertook visual inspections, pH tests and FTIR analysis and concluded that Parafilm MTM was an unsuitable replacement, but that the other materials had undergone no change and had caused no contamination of the host fluids.  

We decided to revisit the samples after an additional 11 years on a south-west facing sunny lab windowsill, for a total of over 14 years of storage in the various fluids.
