Article
In this paper, we used the semiconducting and lightfastness properties of synthetic and mineral arsenic sulfide pigments to study their stability by means of electrochemical and microfadometric techniques. A combination of these techniques shows that in the early stage of the degradation process, amorphous arsenic sulfides are more stable than both...
Article
The consolidating adhesive project is an international collaboration which aims to develop a new adhesive with well characterized physical, optical, and ageing characteristics specific for the consolidation of painted layers. Since starting in 2010, many findings have been made, and new useful polymer-tackifier, and polymer-tackifier-wax blends hav...

Piet Mondrian’s Broadway Boogie Woogie (1942–1943) was examined using Macro X-Ray Fluorescence mapping (MA-XRF) to help characterize the artist’s materials and understand his creative process as well as the current condition issues of the painting. The presence and distribution of key chemical elements was used to identify the main pigments in the...

Jackson Pollock's Number 1A, 1948 painting was investigated using in situ scanning macro-x-ray fluorescence mapping (MA-XRF) to help characterize the artist's materials and his creative process. A multivariate curve resolution-alternating least squares (MCR-ALS) approach was used to examine the hyperspectral data and obtain distribution maps and si...

Two state-of-the-art methods for non-invasive visualization of subsurface (or overpainted) pictorial layers present in painted works of art are employed to study Le portrait, painted by Belgian artist René Magritte in 1935. X-ray radiography, a commonly used method for the nondestructive inspection of paintings, had revealed the presence of an unde...
Article
Painted face artworks often require adhesives during their conservation treatment. Damage or ageing processes that result in cracking, powdering, lifting or similar phenomena can occur, at the interface between two paint layers or between a paint layer and the support. Adhesives need to be applied without compromising the original appearance of the...
Article
A large number of products, both natural and synthetic, have been and are used for the consolidation of flaking or fragile paint layers occurring on paintings, polychrome sculpture, furniture and other cultural objects. Most products in use, which include natural as well as synthetic materials, remain untested. Most synthetic materials used for con...
Article
Many natural and synthetic products have been used for the consolidation of paint layers, but none have been thoroughly tested for this application. This is apparent for most of the synthetic and semi-synthetic adhesives for conservation, many of which are pure polymer resins and dispersions adapted from other industries. They were not specifically...

Although the use of cellulose nitrate paint by David A. Siqueiros (1896-1974) is well documented, when and how he used it is not well established. This article focuses on a technical examination of six paintings Siqueiros made between 1931 and 1949. The paintings analyzed come from two collections: Museo Nacional de Arte in Mexico City and The Muse...
Article
Eileen Gray (1879–1976), renowned designer and architect, created several lacquer block or ‘brick’ screens during her career. Although there are approximately 15 extant screens, the focus of this study is limited to 10 white and black screens with known provenance. Exhaustive archival research, screen examination, and technical and material analyse...

An innovative approach to date fiber-based gelatin silver prints using near-infrared spectroscopy (NIR) and multivariate analysis is presented. NIR spectra were acquired for 152 film stills printed in the USA between 1914 and 1986, and partial least square (PLS) analysis was used to correlate the spectra with the year the photographs were printed....
Article
To establish standard working practices and further understanding of the application of X-ray fluorescence (XRF) spectroscopy to works of art and cultural heritage materials, a series of round-robin tests have been conducted biannually since 2002. In 2008 the round-robin explored the application of XRF to the study of paintings on canvas. Thirteen...
Article
Drawings by Georges Seurat in the collection of TheMuseum of Modern Art were examined for a recent exhibition.Fourier transform infrared micro-spectroscopy (micro-FTIR) has found a shellac fixative on all of the drawingsexamined. It is apparent that Seurat applied this resinbecause it appears in areas corresponding to the early passagesin the drawi...
Article
The effects of three tackifiers on the glass transition temperature, terminal relaxation time, plateau modulus, and steady shear viscosity of polyolefin-based pressure-sensitive adhesives (PSAs) were investigated. Free volume theory and the Gordon-Taylor equation are used to explain the special effects of tackifiers on the glass transition temperat...

Recent results from laser cleaning studies on a painting from Ad Reinhardt’s “Black Square” series (1960’s) are presented. This painting, which travelled extensively, suffered various damages and at one stage was completely over-painted. Unfortunately, this overpaint is not reversible via traditional conservation methods and in this respect test cl...
Article
The development of an adhesive that is a hybrid between a pressure sensitive adhesive and a heat seal adhesive is described. The goal of this project, which is a joint collaboration between the Museum of Modern Art and the Polymer Research Institute, is to develop a preservation quality adhesive for application to RC print photographs. RC prints ar...
Article
The safety and physical properties of commercially available glycol ethers are discussed. While propylene and ethylene glycol ethers have approximately the same physical properties, the former have safer metabolic activities. A table is included to illustrate the range of glycol ethers available. /// On traite de la securité et des propriétés physi...
Chapter
The lining process is described as a method by which a new cloth material is adhered to the back of a painting whose canvas is decayed to such an extent that it can no longer support itself. Due to the close relationship of the paint film to the canvas, the activation parameters employed in the lining process are at risk of changing the appearance...
Article
Several industrially manufactured low molecular weight (LMW) synthetic resins have been investigated for their potential use in picture varnishes. The resins were examined by infrared (IR) spectrometry, gel permeation chromatography (GPC) and differential scanning calorimetry (DSC). Refractive indices (RI) were also determined. The stability of fil...
Article
Long-term accelerated aging in an environment free of ultraviolet (UV) light of dam mar resin films, containing the hindered amine light stabilizer (HALS) Tinuvin 292, shows that for best results the concentration of the additive may be increased to 3% from the previously recommended level of 2%, and also that the benzotriazole UV-absorber Tinuvin...
Article
The effect of titanium white, zinc white and lead white on the drying properties of poppy, walnut and linseed oil are analyzed by differential scanning calorimetry (DSC). All of the fresh films undergo complex thermal transitions between -100 and O°C. For some of the dried films subambient transitions that resemble glass transitions occur at about...
Article
Although films of dammar resin cannot be stabilized against photochemical degradation in the presence of ultraviolet light with currently available additives, a remarkable stabilization is obtained with a hindered amine light stabilizer (HALS) if the ultraviolet component of the light source is eliminated. Even in the absence of UV light the effect...
