Inside the Frames of Stanford White: A Technical Study

Stanford White was an American architect at the architectural firm of McKim, Mead & White in New York, where he was a partner from 1879 until his unexpected death in 1906. Although he was best known for his architectural work and interior designs, The Metropolitan Museum of Art holds over a dozen picture frames that were designed by White. These frames were designed for specific paintings that were painted by White’s contemporaries, many of whom were his personal friends. His elaborate frame designs with distinctive, often architectural ornaments, are fascinating works of art that had not been extensively studied technically. Seven frames, designed between 1889 and 1900, were examined using various analytical techniques. Observations about manufacturing processes and the originality of the surfaces are complemented with findings from archival research, providing valuable insights in American frame making towards the end of the nineteenth century.

Tess Graafland is a junior frames conservator at the Rijksmuseum. She conducted technical research on Stanford White frames as part of an Annette de la Renta Junior Conservation Fellowship at the Metropolitan Museum of Art in 2015-2016.

Understanding curing processes: the case of acrylates

Understanding the structure of oil paint at an atomic level is a dream many of us share. It could provide very valuable information on the effect of temperature, pressure and solvents in the integrity of paintings, and could give us more insight into the atomic level interactions between binding medium and pigments and therefore the degradation processes, and overall it would help us design better guidelines for the conservation of art. Unfortunately, oil paint is a very complex system and before we can attempt to model it at such a scale, methods and models have to be tested in much simpler systems. In this presentation, I will explain the issues behind the modelling of oil paint and present the methodology developed so far to simulate the curing process of polymers at an atomistic level. I will specifically present the case of acrylates, which are commonly used components in resins, coatings and inks.

Ariana Torres Knoop finished her physics degree in 2010, followed by a joint master program between the ENS Lyon and the UvA, with a focus on statistical physics and atomic scale modelling.  She finished her PhD in the Molecular Simulation group of the UvA in 2016 (cum laude). Currently she is involved in the NICAS PREDAGIO project, where she develops and applies methods to simulate the curing process of polymers at an atomistic level.
