The next edition of the NICAS Colloquium takes place on Thursday, 7 December 2017, from 12:00 to 13:00.
The NICAS Colloquium will take place this time in the main conference room of the Rijksmuseum Bureau (Hobbemastraat 20, Amsterdam).
The chair of this colloquium will be Annelies van Hoesel (Rijksmuseum).
The following presentations are scheduled for this edition of the NICAS Colloquium:

A Closer Look at Eduard Isaac Asser’s Family Albums
The Rijksmuseum collection holds four albums with photographs by Eduard Isaac Asser (1809-1894), who took the earliest known photographs of Amsterdam using the paper negative - salted paper print combination. He also experimented with albumen and patented a variation of the photolithography process. Some of the coatings on a number of prints are now severly discolored, cracked or have locally stained pages. Conclusions about the coatings, always assmued to be beeswax or shellac, were made by visual examination only. This project was the first attempt to apply scientific analysis to these significant objects. XRF analysis has collected valuable information about Asser’s technique. FTIR and OCT were useful to determine the nature of the coatings and to study their morphology.
Rosina Herrera Garrido studied Conservation and Art History before she got trained as Photograph Conservator in Rochester (USA). She has worked at MoMA (NY) for 3 years, and here at the Rijksmuseum since 2014.
Conservation, restoration, conservation science and perception - what do people see?
Every day, decisions are made about the treatment of objects of cultural heritage. Since the cleaning controversy, such decisions are often based on the concept of science-based conservation. Advanced, “objective” techniques are used to provide increasingly precise information on objects, techniques ranging from advanced chemical analysis methods and modern (spectral) imaging technologies, to the analysis of the effects of vibration and shock. Furthermore, new technologies are being developed for the so-called virtual retouching of objects. However, the final decision on what to do with an object is ultimately “subjective”, and is based on the opinions and perceptions of the professionals in the decision-making process. But what is it that they, and eventually the public, see? This talk briefly discusses case study based research at the RCE examining these perception issues.
Bill Wei is senior conservation scientist at the RCE. He conducts research on the effects of conservation treatments and vibrations on object condition, appearance and perception.
