Natural Materials
• Natural History Museum holds around
70 million specimens
• Natural origin or artefacts derived from
a natural origin
Challenges
• Collections support the
research of the museum
• Any interventive process
therefore will reduce or change
the value of the object
• Collections are held in an
environment that reduces rates
of deterioration and maximize
data

Digital Collections
Specialist Control
• Standards Review
Ethics
• Preventive Approach
• Object as Data

Specimen Status
Lace and Links
• Natural Materials
– Linen (flax plant, Linum
usitatissimum), Silk (protein
fibre) , Cotton (bolls Gossypium barbadense
– Metals, human hair,
natural history materials
– Hold samples of original
materials
– Role as a research
collection
• Museum holds its
collections as a research
archive
• Conservations role is to
preserve data

we treat specimens
Conservation Research
• Non-invasive Conservation
– Reduced invasive treatments
– Imaging
• Forensic Conservation
– Analysis
– Design
– Aid in preservation at scenes
of crime
– Sampling
– Ensure data for ID accessible
• DNA
• Geneaology
Changing Methodologies
