From the book:
No handicraft receives so much attentive observation as printing. But the observation of the ordinary reader, however attentive it may be, is usually superficial and imperfect. Types are seen but not regarded: it is only the information conveyed by types that is considered. Few general readers know by name the different sizes or styles of types ; fewer still could identify the types made or used by famous printers.

Article: Feasibility of analyzing molecular pigments in paint layers using TOF S-SIMS (2005)

Title: Feasibility of analyzing molecular pigments in paint layers using TOF S-SIMS
Authors: Rita Van Ham, Luc Van Vaeck, Freddy Adams, Annemie Adriaens
Reference: Analytical and Bioanalytical Chemistry 383, 2005, 991–997
DOI: 10.1007/s00216-005-0088-4

A first attempt to measure the molecular compositions of pigments in paintings using static SIMS was made. An investigation of pellets of pure pigments such as auripigment and verdigris allowed the detection of numerous high m/z ions useful for molecular identification. Analysis of pigments in embedded paint fragments, on the other hand, only yielded elemental information because of charge build-up and contamination problems. Optimization of the form in which the sample is presented to the analysis method is obviously the price to pay for the ultimate sensitivity and information depth of S-SIMS.

The gentle art of faking (1922)

From the Preface:

In analysing the Faker one must dissociate him from the common forger ; his semi-artistic vocation places him quite apart from the ordinary counterfeiter ; he must be studied amid his proper surroundings, and with the correct local colouring, so to speak, and his critic may perchance find
some slight modicum of excuse for him. Beside him stand the Imitator, from whom the faker often originates, the tempter who turns the clever imitator into a faker, and the middleman who lures on the unwary collector with plausible tales.
It is not the object of this volume to study the Faker by himself, but to trace his career through the ages in his appropriate surroundings, and compare the methods adopted by him at various periods of history, so far as they may be obtained.

From the Preface:
The topic of this meeting is an important one, as it poses particular challenges due to the constraints often imposed by the building fabric. In addition, the conservation of historic interiors not only draws from many conservation specialisations but also from many other fields. Furthermore, historic buildings and their interiors form part of national heritage of every country and culture. These buildings and their interiors usually consist of multiple facets and materials often altering dramatically throughout their life spans due to change imposed by society, their environment and use. It is through the conservation and restoration of these buildings and the collections therein that the cultural identity of our past can be preserved and transferred to our future. It is thus essential to consider these entities in a holistic manner using a multidisciplinary collaborative approach, without imposing any sense of hierarchy for the conservation of the individual artefacts or collections housed within.

Title: New materials for safeguarding cultural heritage
Reference: ARIADNE 10 Workshop, April 22-28, 2002
Link: http://www.itam.cas.cz/... (pdf)

The workshop will summarise state-of-the-art in the research of new materials for safeguarding of cultural heritage in order to improve and up-to-date mutual information about scientific achievements and capacity of research facilities in the pre-Accession to the EU countries and will support transition of this information to the EU countries as well as to the countries of Community’s external policy interests. It will help to select themes for medium term courses and joint or concerted research in this field and will gather data on relevant national and international funding possibilities. The workshop is aimed to influence cultural heritage research orientation and training of teachers necessary for a sound economic and social local or regional development. All this will be used for relevant networking and twinning arrangements and links among pre-Accession to the EU countries, as well as, between them and the EU countries in the area of cultural heritage research.

This paper describes corrosion potential measurements of corroded copper samples taken whilst acquiring timeresolved X-ray diffraction or X-ray absorption data in a synchrotron beam line. The surface structure of the samples and its evolution, whilst under simulated conservation treatment in sodium sesquicarbonate, were examined using X-ray diffraction. The fluid chemistry over the sample was monitored during identical experiments using X-ray absorption. All measurements were carried out with the sample immersed (i.e. without the need to expose the sample to air). Processes were followed from initial wetting of the surfaces through to the cessation of measurable change. A webcam was used to make a simultaneous visual record of the sample and its environment. The experiments aim at contributing to the improvement of conservation methods for cupreous artefacts recovered from marine environments.

In the past, corroded lead objects have been treated in many different ways. Some treatment methods are based on cleaning the surface, and rely on the dissolution of the stable corrosion layer. Other methods involve the conversion of the corrosion products into metallic lead, and have been used to preserve the design, which is still present in the corrosion layer and which contains information of the original surface. Such techniques work particularly well on lead objects that have been exposed in a humid environment containing organic acid vapours, where an active corrosion crust is likely to develop.The volume of the corrosion products in an active corrosion crust is greater than that of the original metal, resulting in cracking over time, thereby increasing the access of pollutants to the metal below.This overview describes the different treatment methods applied to lead objects; it is not intended to provide practical guidelines with regard to the conservation of lead objects.

Raman spectroscopy is often used for the non-destructive analysis of archaeological objects or artefacts. Recently, the use of mobile Raman instrumentation has become increasingly popular for in situ investigations. Moreover, in this work, direct Raman analysis was completed with Fourier-transform infrared (FT-IR) analysis and scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX). We used a dedicated mobile Raman instrument to perform direct analysis on a series of Shaman paintings on textile, which are part of the collection of the National Museum of Denmark. In general, relatively little attention has been given to the investigation of 19th or 20th Century artworks of Southeast Asian origin. The paintings under investigation depict Shaman gods and were previously dated between 1870 and 1950. The aim of this work was to obtain information on the materials that were applied and to narrow these dates, based on the artists' materials that could be identified. By using the combination of analytical techniques (Raman analysis with FT-IR and SEM-EDX), it was possible to obtain information on inorganic and organic pigments, the binding medium and the canvas.

In this paper, Raman spectroscopy is used for the first time to identify the pigments on decorated antique Iberian pottery. Ceramic fragments of type Real and others from the archaeological excavation in the oppidum Puente Tablas were examined. Different types of iron oxide pigments (hematite and goethite) were identified, along with amorphous carbon. in some samples, the presence of chalk or gypsum could be demonstrated. Some unattributed Raman bands are believed to be associated either with post-burial organic deposition or with silicate materials that are present in red ochre. It was possible to relate the findings with geological data from the region and to make assumptions on a local production.

Lead objects exposed to the atmosphere or buried are known to corrode slightly. However, lead corrodes severely in humid environments, and, more specifically, in the presence of organic acids. This accelerated degradation, commonly referred to as active corrosion, takes place e.g. in display cases of museums and on organ pipes in churches: the objects readily loose mechanical stability and their original surface details. If the process is not stabilized, all details and even the entire artefact could be lost through complete disintegration. A possible treatment to stabilize and conserve active corroded lead is an electrochemical reduction. In this work we have tried to shed some light onto the process. First of all, a fundamental study was performed to understand the mechanism of the ongoing reduction and how it affects the profile of the corresponding reduction curve. In a second part, we focused on the evaluation of the treatment, related to the chemical and morphological changes of the lead artefacts. Finally, we studied the efficiency of the treatment on corroded lead alloys. Therefore, lead and lead alloys, including lead-tin, lead-antimony and lead-bismuth were artificially corroded by vapours of formic acid, acetic acid, propionic acid and acetaldehyde at different concentration levels. Consequently, the electrolytic reduction of the corroded coupons was studied to evaluate the effects of the alloying elements. In this work, we studied the application of lead decanoate, deposited by immersion in sodium decanoate solutions. We focused on the lead decanoate layer growth in situ using electrochemical impedance spectroscopy and X-ray diffraction, in order to obtain insights in the protection and growth properties. The preparation of decanoate solutions was investigated and resulted in the establishment of a protocol for a solution that produces rigid coatings. Using this solution, we studied the lead decanoate surface coverage on a basis of solid/liquid contact angle measurements at regular time intervals during treatment. In addition, we monitored the coating resistance during application by electrochemical impedance spectroscopy and studied effects of stirring and of the layer thickness of the liquid phase to determine most efficient application conditions.

Throughout human history, forests and woodlands in Western Europe experienced a high anthropogenic influence. In densely populated areas forests were cleared and converted to arable land or were exploited for the supply of firewood and construction timber. In Flanders, it is estimated that the forest cover by the end of the 13th century was even lower than in the 19th century. To date, several assortments of timber, available on the local wood market during the Roman era and the Middle Ages, have become part of our cultural heritage. Archaeological remains, historical buildings, panel paintings and religious sculptures are only a few examples of constructions and objects that were created by processing wood. Especially European oak (Quercus robur L. and Q. petraea (Matt.) Liebl.) was highly esteemed by craftsmen. Tree-ring series of oak have the characteristic that they tend to crossdate. In other words, ring-width series display a certain element of synchronicity between remote sites. This feature allows to use dendrochronology, i.e. the scientific study of tree-ring patterns, as a dating tool. However, in Flanders tree-ring dating has seldom been applied and has often led to inconclusive results. Especially archaeological oak timbers or wood from historical buildings is often characterized by short (less than 50 years) and variable growth patterns. Therefore, it was assessed and demonstrated that such series have a potential for dating purposes and chronology building. It is believed that the high anthropogenic pressure on the original forest cover has stimulated the implementation of short rotation systems. Past forest management interventions and forest stand structure development are recorded in the growth patterns and the wood anatomical structure of archaeological and subfossil wood. By comparing them with growth patterns of contemporary trees from stands with well-known stand structure and management history it was noticed that the same patterns are encountered. Consequently, it is now possible to distinguish wood specimens that originate from, for instance, a coppice stand or a high forest by scrutinizing their growth patterns. Moreover, close observation of the wood anatomy, for instance, the size and distribution of earlywood vessels, provides an image of the variability in past hydrological conditions. Tree-ring series from wooden sculptures and panel paintings from 15th-16th century display a completely different nature. Since local timber sources mostly provided small sized and fast grown timber, craftsmen started to look for high-quality oak. Such assortments became available due to the establishment of an important timber trade. Especially oak timber from the Baltic region was imported. By studying the growth patterns on historical art objects it becomes clear that medieval woodworkers were well aware of the intrinsic variability and technological properties of the imported oak timber. Moreover, analysis of extensive datasets of tree-ring series from historical art objects provides more insights and information on the original timber source, wood processing activities and the creative process. It is obvious that dendrochronology has become more than a dating tool in (pre-) historical studies. This work demonstrates that it is highly valid to approach Flanders’ precious cultural heritage, created out of wood, from a multidisciplinary point-of-view, where archaeology, art-history, wood technology and biology should play an important and valuable role.
