Although it’s only been a few weeks since I looked at ‘what lies beneath,’ it feels like a lifetime as so much has happened to our blue whale skeleton in a relatively short space of time. The biggest challenge of de-installing the skeleton from the Mammals Hall has been completed with resounding success and the Conservators are now busy with the next phase of cleaning and conserving each individual bone.
We all knew that safely removing the bones from the 81 year old armature was not going to be easy. Add in the fact that it was suspended over a large model of a blue whale and several other specimens with very little room for manoeuvre and you start to appreciate the whale-sized nature of the project. This post outlines what happened during the de-install.
The team have been busy in the 3 weeks since my last post, studying the blue whale skeleton and documenting its condition. The first stage was to record the initial condition of the skeleton, including the coating of dust that has accumulated over time, and to start to identify areas which would require attention prior to dismantling.
Dust particles that are deposited on museum objects will typically consist of fibrous material (aka “fluff”) and non-fibrous particulates. Dust is hygroscopic and can accelerate biological, chemical and physical deterioration of specimens and even though it is over 6 metres above the ground, the whale skeleton is a dust attractor so a regular cleaning schedule is important where practicable. On this occasion, over 1.3 kilos of dust was removed from the blue whale skeleton during this initial clean.
