It has been several months since my last post looking at blue whale on the move but finally the long process of cleaning and conserving each individual bone has been successfully completed and the conservators are now just embarking on surface scanning the bones in high definition. Conservation can be an extremely slow process but it is worth the time and effort. During the past 9 months the team have cleaned and conserved over 220 individual bones. This equates to over 110m2 of whale bone surface area.

During this time we also planned the final position and articulation of the whale for its suspension in Hintze Hall so the armature design could commence. This post outlines the conservation treatment and articulation planning phase of this project.
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.
