Abstract
ABSTRACT The Harrison D. Horblit Collection of Early Photography at Houghton Library, Harvard University contains 370 paper negatives, presenting an opportunity to study this nineteenth century technique in depth. In a pilot study on the composition and light stability of paper negatives by the French artist Frédéric Flachéron (1813–1883), nine paper negatives were analyzed with X-ray fluorescence analysis and three with microfade testing to ascertain if there was a correlation between the presence of halides and the light stability of the negatives. Technical analysis identified iodine and bromine in the negatives and indicated variability in Flachéron’s stabilization and fixing methods not previously documented.
期刊介绍：
The American Institute for Conservation is the largest conservation membership organization in the United States, and counts among its more than 3000 members the majority of professional conservators, conservation educators and conservation scientists worldwide. The Journal of the American Institute for Conservation (JAIC, or the Journal) is the primary vehicle for the publication of peer-reviewed technical studies, research papers, treatment case studies and ethics and standards discussions relating to the broad field of conservation and preservation of historic and cultural works. Subscribers to the JAIC include AIC members, both individuals and institutions, as well as major libraries and universities.
