Skin Costumes Online

In October 2014 The Danish National Museum, in collaboration with the National Museum of Greenland and the Museum of Cultural History, Oslo, published the website Skin Costumes Online at http://skinddragter.natmus.dk/. This website is available both in Danish and in English.
 

Skin Costumes Online shows high-resolution photos and detailed information of outstanding and historic skin costumes from the indigenous peoples in Greenland, North America, North Scandinavia and Siberia.

Through the website easy access will be given to this rich cultural heritage, from museums' collections. 

This project was supported by The Nordic Culture Fund, Augustinus Fonden, Knud Rasmussen Fonden and the National Museum of Denmark through the research program Northern Worlds 2009-2013.​

Abstract:

This paper examines the impact of heat-induced oxidation for new and historical parchment with the purpose of improving diagnostic tools for use in practical parchment conservation. Oxidation was generated by heat aging at 120°C in a dry oven for 24, 48, and 96 hours, respectively. The degradation was assessed on all samples at macrolevel by measuring color changes, at microlevel by measuring the shrinkage temperature as well as by performing a visual assessment of the fibers’ morphology and determining the amount of damaged fibers, and finally, at molecular level where amino acid analysis was used to reveal changes in the oxidized collagen. The study shows that the heat-induced oxidation leads to significant color changes, decrease in hydrothermal stability, as well as changes in the amino acid composition. Surprisingly, the results show that the historical parchment is more sensitive towards dry heat oxidation on a molecular level than is the new parchment. Furthermore, for the first time, we can show that physical damage reflected in the morphological characteristics of fibers can be attributed to oxidation by dry heat.
