Folding Screens

The painting materials and drawing techniques of a pair of two-panel folding screens entitled Red and White Plum Blossoms by Ogata Korin, a national treasure in Japan, were investigated directly and nondestructively by XRF, X-ray radiography, and high resolution digital imaging. Several assumptions were made about the materials used in the red and white plum trees drawn on the right and left screens, respectively, and the river drawn at the center. By the present investigation, the materials used for the paintings were revealed, and some of them contradicted what have been previously believed.

High Resolution Images

A Be-window-type X-ray zooming tube is an X-ray digital imaging system whose magnification factor of X-ray images can be easily varied from 10 to 200, and whose spatial resolution is less than 0.5 µm. This zooming tube was used as an imaging detector in double-crystal X-ray topography to obtain high-resolution images of dislocations in a silicon crystal. X-ray interference images of about 5 µm were observed even though optimal performance of the X-ray zooming tube could not be achieved. The results indicate that the X-ray zooming tube might make a good detector for X-ray topography with minor improvements in its stage structure.

Abstract This study presents a physicochemical analysis on the orthodox icon “The grieving Mother” from XIXth century. The icon is made by an anonymus painter, in tempera pigments, on a lime wood support, Tillia cordata. God’s Mother is represented from one side, only the bust, with the head down, framed by a white border. The predominant colors of the icon are ultramarine blue, ocher, red-brown, with silver leaf. The edges of the panel were painted with tempera pigments as the border. On the right edge an inscription in blue ink, can be seen, but is unreadable. The painting layer has gaps, fissures, detachments, dirt, degraded and scaly varnish. The panel is made from a single board, transversally cut, without crossbeams. The study is based on the identification of some archeometric characteristics of the wood panel and of the pigment layer. To determin painting materials and the conservation state, Fourier Transform Infrared Spectroscopy (Micro-FTIR) and Scanning Electron Microscope coupled with Energy Dispersive X-ray spectroscopy (SEM-EDX) were employed. Using this methods we identify the pigments used and the state of degradation of the panel. The FTIR spectrum analysis showed that the pigment layer contains schellac varnish, ultramarine blue and dust, a conclusion supported by SEM-EDX analysis.

This paper presents the results of three different approaches applied to the newly-restored titular painting entitled <em>The Conversion of St Paul</em>, the main altarpiece in the Mdina Cathedral in Malta. This large, dramatic painting is the work of the Baroque artist, Mattia Preti, known as <em>il Cavaliere Calabrese</em>. Here, we focus on the results of the digital photogrammetric survey that adopts image-based approaches for 2D/3D model reconstruction. The model was used to quantify important features of the painting as well extensions of the areas restored. In addition, portable X-ray fluorescence and Raman spectroscopies were used to non-destructively identify the nature of the painting materials, at the elemental and molecular spatial scales, respectively, with the ultimate goal of reconstructing the colour palette of the artist. The 3D model developed here could be applied to other paintings of Preti to conduct comparisons between different measurements in the paintings, with the main goal of clarifying the technique used by the artist. This information, along with the characterisation of the materials used, is crucial for the reconstruction of the historical–geographical context of the artwork, since specific pigmenting agents and media tend to represent the stylistic expression of an artist or an epoque.

Molecular Structure Analysis

Proteolytic digestion of the immunoglobulin IgG with papain cleaves the molecule into an antigen binding fragment, Fab, and a compliment binding fragment, Fc. Structures of intact immunoglobulin, Fab and Fc from various sources have been solved by X-ray crystallography. Rabbit Fc can be crystallized as thin platelets suitable for high resolution electron microscopy. The structure of rabbit Fc can be expected to be similar to the known structure of human Fc, making it an ideal specimen for comparing the X-ray and electron crystallographic techniques and for the application of the molecular replacement technique to electron crystallography. Thin protein crystals embedded in ice diffract to high resolution. A low resolution image of a frozen, hydrated crystal can be expected to have a better contrast than a glucose embedded crystal due to the larger density difference between protein and ice compared to protein and glucose. For these reasons we are using an ice embedding technique to prepare the rabbit Fc crystals for molecular structure analysis by electron microscopy.

Polytypism has been studied for a number of years and a wide variety of stacking sequences has been detected and analysed. SiC is the prototype material in this respect; see e.g. Electron microscopy under high resolution conditions when combined with x-ray measurements is a very powerful technique to elucidate the correct stacking sequence or to study polytype transformations and deviations from the ideal stacking sequence.

Resolution Study

The phenomenon of clustering in Al-Ag alloys has been extensively studied since the early work of Guinierl, wherein the pre-precipitation state was characterized as an assembly of spherical, ordered, silver-rich G.P. zones. Subsequent x-ray and TEM investigations yielded results in general agreement with this model. However, serious discrepancies were later revealed by the detailed x-ray diffraction - based computer simulations of Gragg and Cohen, i.e., the silver-rich clusters were instead octahedral in shape and fully disordered, atleast below 170°C. The object of the present investigation is to examine directly the structural characteristics of G.P. zones in Al-Ag by high resolution transmission electron microscopy.
