Furskin Identification Program Website
Furskin Identification Program
http://www.furskin.cz/
FURSKIN is the first program created for fur skin identification which has allowed a very quick and exact comparison of structural patterns and eliminates much of the tedious work associated with the use of the Atlas book.
In 2006, fur skin micro-structural data was transferred into the Internet version of FURSKIN (http://www.furskin.cz/). In this website, the Furskin Identification program is described for rapid analysis and identification of fur skin species. The identification is based on a wide collection of fur skins micro-morphology and their microscopic patterns.

"The preservation of Inuit clothing..." by Carlsen et al (1995)
Carlsen, L.; Feldthus, A.; Schmidt, A. L.; "The preservation of Inuit clothing collected during the Fifth Thule Expedition (1921-24) ", Arctic 48(4) (1995) 333-337
URL / PDF
Abstract:
Preparation procedures as well as ordinary use apparently cause changes in the appearance of Inuit skin clothing. These changes may alter the inherent properties of skin, such as fatty acid composition and shrinkage temperature. The present paper describes studies of fatty acid distribution and shrinkage temperature in a series of items of Inuit origin collected during the Fifth Thule Expedition (1921-24). The skins used for the clothing originate from ringed seal (Phoca hispida) and caribou (Rangifer tarandus). For comparison, fresh prepared skins were studied, as were samples of sealskins found in the mummy burial ground in Qilakitsoq, Greenland. It appeared that ordinary use changed the fatty acid distribution to some extent, as well as the shrinkage temperature, indicating slow deterioration. However, more significant deterioration was observed for samples exposed for longer periods to daylight as, for example, when placed on exhibition. The effect of light was verified by studying samples deliberately exposed to full daylight for ca. 6 months. In contrast to these samples, the 500-year-old skins appeared, on the basis of fatty acid distribution and shrinkage temperature, to be in good condition, possibly because of the lack of ordinary use in combination with low storage temperatures.
Résumé:
Les méthodes de préparation ainsi que l'utilisation normale provoquent, semble-t-il, des changements dans l'aspect des vêtements de peau inuit. Ces changements peuvent modifier les propriétés inhérentes de la peau, telles que la répartition des acides gras et la contractilité thermique. Cet article décrit les études portant sur la répartition des acides gras et la contractilité thermique dans une série d'objets d'origine inuit recueillis au cours de la cinquième expédition de Thulé (1921-24). Les peaux servant à l'habillement viennent du phoque annelé (Phoca hispida) et du caribou (Rangifer tarandus). À des fins de comparaison, on a étudié des peaux récemment préparées, ainsi que des échantillons de peaux de phoque trouvées dans le cimetière de momies de Qilakitsoq, au Groenland. Il semble que l'utilisation normale ait changé, dans une certaine mesure, la répartition des acides gras ainsi que la contractilité thermique, indiquant une détérioration lente. On a toutefois observé une détérioration plus importante pour des échantillons exposés durant de plus longues périodes à la lumière naturelle comme, par exemple, lorsqu'ils sont mis en exposition. On a vérifié l'effet de la lumière en étudiant des échantillons délibérément exposés au grand jour pendant environ six mois. Par contraste avec ces échantillons, les peaux de 500 ans semblaient, si l'on se fiait à la répartition des acides gras et à la contractilité thermique, en bon état, et ce, en raison peut-être du manque d'utilisation courante combiné à un entreposage à basse température.

"... understanding of archaeological hide-working processes" by Beyries and Rots (2005)
Beyries, S.; Rots, V.; "The contribution of ethno-archaeological macro- and microscopic wear traces to the understanding of archaeological hide-working processes", in L. Longo and N. Skakun (eds.), "Prehistoric Technology” 40 years later: Functional Studies and the Russian Legacy (2005) 21-28
Summary
Ethno-archaeological data allow a better understanding of the hide-working process including parameters such as haft morphology, tool position and angle of insertion, tool fixation, thickness of the hide worked, the position of the hide/hide-worker, the precision of the gesture, etc. While these kinds of data are difficult to infer for archaeological tools when based on an experimental reference, we believe that it is possible if the analysis is based on a close examination of the wear traces produced in ethno-archaeological conditions. Based on different ethno-archaeological case studies, we propose criteria that – when applied in functional analyses of archaeological tools – allow a more complete understanding of the parameters involved in the archaeological hide-working process. It is concluded that this research demonstrates the importance of ethno-archaeology as a research tool in functional studies.
Résumé
Certaines données ethno-archéologiques peuvent contribuer à une meilleure compréhension du processus du travail des peaux, par exemple la morphologie du manche de l’outil, la position et l’angle de travail de l’outil, l’épaisseur de la peau, la position de la peau / l’artisan, la précision du geste, etc. En se fondant exclusivement sur des données expérimentales certaines de ces données sont difficilement accessibles. Cependant, les auteurs suggèrent qu’en s’appuyant sur une analyse détaillée des traces produites dans des conditions ethno-archéologiques les interprétations archéologiques peuvent être beaucoup plus précise. Cette recherche démontre l'importance de l'ethno-archéologie comme outil de recherche dans des études fonctionnelles.

Layers of meaning: clothing on the Amur by Rajagopalan (2003)
Rajagopalan, S.; Layers of meaning: Clothing on the Amur, e-publication of The National Museum of Ethnology, Leiden (2003)
PDF
Introduction:
In the Amur region of southern Siberia, the production of clothing and the beliefs associated with its making and wearing reveal an extreme fluidity of boundaries between the human and animal world. This publication discusses the clothing cultures of two groups – the Nivkhi and Orochi. It explores the making of clothing, the motif patterns peculiar to this region, sewing as a woman’s preserve, and the changes in Amur clothing from the pre-Soviet to the post-Soviet period.
Principles of Amur clothing
Until the early decades of the twentieth century, the Nivkhi and Orochi used mainly fish skin and animal furs for their clothing. The use of fish skin or animal pelts for clothing speaks of the centrality of fishing and hunting in these cultures.
The making of fish clothing (skin of salmon and carp is particularly suitable) characterizes the Nivkhi to the extent that early Chinese records of the people referred to them as 'fish skin tribes'. Their fish skin clothing distinguished them from other neighbouring groups and became a crucial marker of their identity.

Inleiding:
In het gebied rond de rivier de Amoer in zuidelijk Siberië is duidelijk te zien dat bij het maken en dragen van kleding en de opvattingen die hierbij een rol spelen, de grenzen tussen de werelden van mens en dier in hoge mate in elkaar overvloeien. In deze publicatie worden de kledingculturen van twee groepen, de Nivch en Orotsj, behandeld. Er wordt uitgebreid ingegaan op het maken van de kleding, de streekspecifieke motieven, het naaien als domein van vrouwen en de veranderingen in Amoer-kleding van de pre-sovjet- tot de post-sovjetperiode.

"Identifications, microanalysis, evaluations and diagnosis of an ethnographical leather object"
http://www.ndt.net/article/art2008/papers/135Bernath.pdf
Abstract:
The aim of this study is the examination, documentation, analysis and diagnosis of a headgear with bit and reins, made of leather and metal, from Abyssinia (the old name of Ethiopia), belonging to Karl F. Jikeli collection of “Franz Binder” Museum, from “ASTRA” National Museum Complex, for the purpose of drawing up the object conservation strategy. Due to the scarce information regarding the artifact, we started our work by trying to confirm the object origins, and carried out all the available investigations for a good documentation. After accurate visual and microscopic comparative examinations that revealed the different leather natures and their surface states, we used micro-chemical analysis for identifying various tanning procedures, the presence of fats and copper, etc. Furthermore, in collaboration with INCDTP – Division Leather & Footwear Research Institute, we have been doing a series of specific and advanced analyses, as the employment of the micro hot table (MHT) technique to obtain relevant results, and measurements/ evaluations on the grain of various leathers. All investigations not only revealed some interesting and detailed but also necessary information for a proper diagnosis and planning of the various stages of the conservation activity.

"Inside the parchment"
http://www.ndt.net/article/art2008/papers/140Bicchieri.pdf
Abstract:
Even though parchment has been applied as library and archive substrate for centuries, this material’s structure and degradation patterns are less explored than paper’s ones. In this preliminary work vibrational studies highlighting distinction between parchment components are presented. Advances in conservation methods can in fact be achieved by an improved knowledge of the microscopic and spectroscopic features of the parchment components.
Studies of the chemical interactions with the products used in manufacturing and writing will be presented. Standard glycine, proline and hydroxyproline FTIR spectra were compared to different kind of parchment and other collagen-based materials. Some samples were inked with different kind of inks (carbon black, iron-gall, carbon black mixed with iron II sulfate or iron-gall) other subjected to invasive treatments so as to simulate damages induced by catastrophes or by a recently developed restoring treatment. Spectral variations due to artificially induced modification of parchment were monitored and analyzed.

"Two early medieval parchment manuscripts- study of component materials"
http://www.ndt.net/article/art2008/papers/146Geba.pdf
Abstract:
Within the Restoration-Conservation Centre for Cultural Heritage of Iasi two early medieval manuscripts on parchment (Tetra Evangel and The Greek Evangel) were investigated. The restoring of these manuscripts gave the opportunity of a thorough research on the writing materials, pigments used in the ornamentation and the base material. The study of the base material, carried out by IR spectrophotometry (Transmission and ATR), lead to the identification of a natural polypeptide (parchment) (specific bands at 1630 cm-1- amide I and at 1530 cm-1 - amide II), and also of calcium carbonate (chalk), used as surface covering material. Concerning the writing materials we identified ferro - gallic ink (The Greek Evangel), a mixture of ferro-gallic and carbon ink (Tetra Evangel – the first part), carbon ink (Tetra Evangel – the second part) and a cinnabar red ink (Tetra Evangel. The decoration of both manuscripts (frontispieces, lateral bands, frames, miniatures) are of a large chromatic varieties. The pigments were identified by optical microscopy, micro chemical tests and XRF. The pigments determined are: gold (Au), iron oxides (Fe), cinnabar, malachite, transparent copper green, madder lake, lead carbonate (Pb).The phosphorus (S) identified may come from a protein (yolk), used as glue or protection layer. The similarity of decoration materials points to the manufacture of both manuscripts in the same area of the Byzantine culture. One manuscript (Tetra Evangel) was subjected to restoration, in order to stop and remove the physical, chemical and biological deteriorations (undulations, brittleness, chromatic alterations, pigments flaking). The restoration operations consisted in cleaning, dressing, flattening, voids infilling and pigments consolidation.

"Study of the effect of laser cleaning on collagenous structures"
http://www.ndt.net/article/art2008/papers/153Simileanu.pdf
Abstract:
Cleaning procedures applied on organic substrates of artifacts can be challenging due to their high sensitivity to all exterior factors, their fragile nature demanding a high precision and accurate monitoring of the cleaning process. This paper contains researches about the effect that the laser restoration procedures (laser cleaning, mainly) induce on organic substrates such as leather and parchment. Laser cleaning of leather & parchment is a novel technique that has the potential to provide contactless, chemical-free cleaning of historically important documents, overall providing a high accuracy successful cleaning. However, the effect of laser cleaning on the collagenous structure of parchment is still poorly understood, as is the effect of the wavelength or the energy density (fluence level). This study comprises aspects of the ageing of the materials and also specific issues concerning conservation of their photomechanical properties, correlating information obtained using specific scientific methods of analysis such as colorimetry, optical microscopy, shrinkage temperature of the organic fibers and NIR Spectroscopy. Surface monitoring based on chromatic modulation has been carried out for the laser cleaning of different types of leather and parchment samples, working with the spectral signature of reflected light from the surface. Results show that the spectral parameters derived from the chromatic detection provide not only clear indication of the surface cleanliness and the substrate damage but also useful chromatic information on the surface. The outcome of these experiments consists in an on-line control of laser induced material removal from artworks under restoration, phenomena encountered in photo-induced ablation.

"Non-Destructive Investigation of the Dead Sea Scrolls"
http://www.ndt.net/article/art2008/papers/209Hahn.pdf
Abstract:
The Dead Sea Scrolls belong to the most important cultural assets of mankind. Their long term preservation and study is a challenge that demands an interdisciplinary approach. As early as the 1950s natural scientists assisted the scholars in studying the scrolls. It was at this time that the first extensive study of the scroll material took place. It was found that most fragments were written not on leather but on parchment. In addition, a method for determining the age of the parchment was developed which is still of value today. In the 1990s the AMS-C14 method confirmed the palaeographic determination of the age of the manuscripts. The use of carbon ink throughout the scrolls is also consistent with the known scribal practices of that time. There are, however, manuscripts, and among them the famous Genesis Apocryphon Scroll, which exhibit ink corrosion, normally associated with iron-gall inks. Today, 60 years after their discovery, a community of scientists from the Jewish National and University Library (JNUL), the Technical University of Berlin (TU Berlin), the Federal Institute for Materials Research and Testing (BAM) and Fritz-Haber-Institute of the MPG (FHI) set out to scientifically investigate the finds of Qumran using the most modern methods. The results of the study will be used to determine the provenance of the texts as well as to contribute to their long-term preservation. A considerable part of the non-destructive investigation is taking place in the Berlin State Library and at the Berliner Elektronenspeicherring-Gesellschaft für Synchrotronstrahlung , BESSY II. Preliminary investigations, performed at the BAM on some fragments, were used to evaluate the extent to which X-ray analytical methods can provide information regarding the geographical origin of the fragments and match the individual pieces. The interpretation of the measurement results is made more difficult by age and storage of the objects. It is believed that ageing processes as well as conservation methods have altered the samples in addition to the changes caused by environmental influences. In collaboration with the TU Berlin, the samples from the parchments found in the caves near Qumran were tested by means of three-dimensional synchrotron based X-ray fluorescence analysis (3D-SyXRF). The aim of this non-destructive investigation was the identification of the inorganic material used in the manufacture of the parchments.
The XRF experiments are supported by the non-destructive analysis by means of synchrotron based infrared spectroscopy (SyFTIR) in collaboration with BESSY II as well as optical and electron microscopy in collaboration with Fritz-Haber-Institute (FHI).

Report of the Committee on leather for bookbinding (1905)
Royal Society of Arts & Worshipful Company of Leathersellers (ed.), Report of the Committee on leather for bookbinding, George Bell & Sons, London (1905)
InternetArchive
From the introduction:
The decay of leather used for bookbindings has for long been a subject which has attracted a great deal of attention and interest amongst librarians and book collectors. The first attempt to investigate the conditions leading to such decay appears to have been made by Faraday, whose historic researches into the condition of the library of the Athenaeum Club in 1842 still remain the only serious attempt made to investigate this subject. Of late years the matter has received still more earnest attention, owing to a growing belief among librarians that the quality of the leathers now made for bookbinding purposes is inferior to that made previous to, say, the middle of the last century. The matter has been discussed on several occasions at meetings of the Library Association, and in the year 1899 a meeting of persons specially interested in the question was held at the Central School of Arts and Crafts in Regent Street, under the chairmanship of Mr. Cobden-Sanderson. This meeting formed itself into a Committee to encourage the production of sound and durable leather for bookbinding. The Committee held several meetings, and some of its members carried out a good deal of investigation and experiment, but it appears to have come to the conclusion that the matter was too large a one to be dealt with by a separate and informal body of the sort, and it was decided to request the Council of the Society of Arts to undertake a thorough investigation of the whole question, and, after having done so, to issue a Report upon it.

Abstract:
Representative samples of the new parchment were prepared to be in an advanced state of degradation by application of artificial heat ageing. The degraded aged samples are submitted to experiments concerning applied consolidation materials (polymers) on parchment. The purpose of this study is to establish if an increase in the properties of parchment can be attained with none or as less as possible interference with the appearance of the object. A comparison is made between six polymers by impregnation method. Investigation of some mechanical properties, change of color and the humidity sorption were used to evaluate the studied polymers. The results revealed that the polymers, which dissolved in organic solvents, were better than that dissolved in water.

Introducción:
La artesanía de la piel y el cuero e industrias derivadas gozó de gran tradición en los Estados de la antigua Corona de Aragón, artesanía, por otra parte, necesaria y universalmente ejercida. El propósito de las pácinas que siguen es presentar una panorámica de esta industria, especialmente en la Baja Edad Media, en diferentes localidades del reino de Aragón así como en las ciudades de Barcelona, Mallorca y Valencia, estableciendo analogías y diferencias entre unos y otros reinos, e incluso la nomenclatura exacta de cada actividad en los distintos lugares.
