It’s All In the Preparation: Part 2

With our sample set chosen, our substrate selected, and our sample mounts determined, we next needed to devise a process for applying the dyes. Since the ultimate treatment would likely involve airbrushing, we chose to spray deposit the dyes onto the quartz plates. For this we had to consider and anticipate the different requirements and…

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…

The Dye Is Cast

The initial sample set undergoing accelerated aging in our Q-SUN chamber is expected to be the largest. It includes all of the Orasol dyes that we have been able to acquire to date from the manufacturer BASF and retail supplier Kremer Pigments, as well as Sorasolve dyes available from Museum Services Corporation (MSC). This post…

Renovation of the Bernard Family Hall of North American Mammals, Part I: What is a habitat diorama?

In 2011-12, the American Museum of Natural History undertook an ambitious program of renovation to the 45 habitat dioramas in the Bernard Family Hall of North American Mammals.  It was important that the unique features of each diorama be preserved throughout the renovation project, which played a role in deciding what kind of materials could…

Introducing the Recoloring Taxidermy Research Project

In 2013, the American Museum of Natural History and Yale University’s Institute for the Preservation of Cultural Heritage and the Peabody Museum of Natural History were awarded an Institute for Museum and Library Services‘ (IMLS) National Leadership Grant to fund a three-year project devoted to the development of best practices for recoloring faded mammal taxidermy…
