Case Study: Flying Squirrel Treatment

Another of the specimens treated as part of our preparation for our Care of Historic Mammalian Taxidermy workshop at the Society for the Preservation of Natural History Collections (SPNHC) 2017 annual meeting was a taxidermy giant red flying squirrel. Project Intern Logan Kursh executed the treatment. There was little data available about the date or…

Case Study: Lemur Mount Treatment Part 2: Treatment

In addition to thorough condition examination and photographic documentation, conservation treatment decisions should begin with a clear proposal to be approved by Collections Managers, Curators, or other stakeholders prior to beginning hands-on work. Caitlin submitted the following treatment proposal to the Mammalogy Department for the treatment of the lemur mount.  Treatment Proposal Use a HEPA-filtered variable-suction…

Case Study: Lemur Mount Treatment Part 1: Condition Examination

In addition to testing the stability of metal-complex dyes, we have been studying condition issues facing historic taxidermy collections (see our previous posts on the Mammalogy condition survey) and performing conservation treatments on selected specimens. These treatments stabilized important mounts and served as case studies for a workshop on the Care of Historic Mammalian Taxidermy…

Surveying Historic Taxidermy Part 3: Results

Our condition survey of historic mammalian taxidermy in the American Museum of Natural History’s Department of Mammalogy (see previous post), supplied an understanding of the most common condition issues affecting them, and clearly displayed their probable causes. Cracks, Splits, and Dust: Responses to Environment It is not unusual to find cracks and splits in historic…

It’s All In the Preparation: Part 1

As earlier posts have mentioned, the first phase of our research aims to establish the lightfastness of the Orasol® and similar Sorasolve metal-complex solvent dyes in isolation‒ that is, in the absence of a binder, and without a chemically active substrate that could potentially influence the behavior of the dyes or interfere with the measurement…

Accelerated Aging Chamber, Part 2

Part 1 of our posts on accelerated aging instrumentation introduced the Q-SUN Xe-3 accelerated aging chamber. In this posting we describe some of the challenges we have experienced in installing and operating the machine; challenges which were unexpected and eye-opening. Problem-solving these situations has been such an important learning experience for us, demonstrating what taking…
