AbstractIt is not well known that the mountings of Tibetan paintings have an iconography and a cosmogeneric relationship to the painting. Hence, a painting without its mounting is incomplete. The iconography is described and the cosmogeneric relationships are discussed, leading to the suggestion that, where possible, the original mounting should be conserved or a logical replacement made. The structure and manner of construction of mountings is shown and described in order to provide a basis for repairs. Four major style varieties are shown as an additional guide in reconstruction. A glossary of Tibetan terms is included for reference. 相似文献

AbstractThe treatment of flaking pigment on two paintings, one on ceramic and the other on glass, is described; a brief history of painting on glass and ceramics places these works in context. The treatments are discussed in relation to other types of treatment for paintings on similar rigid supports. The longevity of the conservation methods used is discussed, as are the results of re-examination of the objects some years after the completion of the treatments. 相似文献

AbstractThe restoration of the Hedin altar in Rothenburg o.d.T., dated 1466, is described. The polychromed sculptures were cleaned and loose paint was fixed. Methods and materials used in the restoration of the paintings, the areas polychromed in various techniques and the brocade reliefs are mentioned. The altar was protected from direct sunlight. The construction of the shrine and the technique of carving are extensively discussed. Sculptures made from one piece of lime wood were hollowed out and closed with a plank. Traces of rough finishing are visible. Shrine and predella were polychromed after a preliminary assembly of the sculptures. The various techniques used in the undisfigured polychromy are described as they are observed with the unaided eye. It can be shown that the working methods were rational. The fabrication of relief brocades and the various patterns used are discussed in detail. The treatment of the various paintings on the wings, the predella and the reverse of the shrine is reported. The question is raised to what extent the painter Herlin can also have been responsible for the polychromy. 相似文献

AbstractThe investigation of materials found in Bacon's studio is reported. The contents of the studio are examined and interpreted to identify the materials and colours most favoured by Bacon, and the range of media used. A small number of colours appear to have been heavily used. Some objects used as tools in the painting process are also investigated and explain textures seen in paint in his works. Samples of selected materials from the studio are analysed to identify the components of paints (pigments, extenders, and binders) used by Bacon. This investigation is part of a wider project examining his materials and techniques. The analytical information obtained here from the studio helps to clarify the statements made by Bacon in interviews regarding his use of materials and is proving useful in the identification of materials in his paintings, in order to help with the conservation and authentication of his works. 相似文献

AbstractBeing prepared to address an attack on a painting requires considerable input from both scientific and conservation personnel. When tailoring an appropriate and effective incident response, a well-developed knowledge of the collection, the museum layout, and staffing is also essential. This article discusses the nature of attacks on paintings and the materials and techniques used to mitigate the effects of malicious damage. Previous research into response procedures and the testing of attack substances is also summarized. The primary focus of the article traces the redevelopment of the National Gallery incident response grab bag that caters to various types of attack. Discussions center on developing the customized content of the new bag, material testing, and a practice run-through to establish a response procedure. Ultimately, the practicality and efficacy of the grab bag are demonstrated. 相似文献

AbstractThis paper discusses the technical examination of Christ in Martyrdom, painted in 1690 by Fra. Ricardo Pilar for the Monastery of São Bento, Rio de Janeiro, Brazil. The painting, which hangs in the sacristy, has recently been restored; this restoration and three previous restorations are described. The characteristic pose of Christ in the composition has been found in mediaeval German sculpture and was popular in Spanish painting in the sixteenth and seventeenth centuries. The techniques used for Christ in Martyrdom have been compared with contemporary Spanish and Portuguese treatises and selected paintings in the collection of the National Gallery, London, to illustrate Pilar's original style. The palette and the linseed oil medium are typical of Spanish painting and are likely to have been imported from Europe. 相似文献

AbstractA very moderate, non-destructive radioactivation of oil paintings, induced by thermal neutron bombardment, such that approximately only one in 1012 of the atoms comprising any painting is transformed into a radioactive species, has been found to produce temporary radioactivity sufficient to expose photographic film placed in direct contact with the paintings.The resulting autoradiographs resemble conventional X-radiographs in that they reveal structural details in depth of both the painting and its support. Since the radioactivities arising from the different elements within a painting decay in different manners and at different rates, a series of significantly distinct auto radiographs can be obtained of any painting by making exposures through appropriate filters and at varying times following the original activation. Analysis of such a series of autoradiographs permits the identification of a number of the pigments used in a painting, together with information about the manner in which they were originally laid down by the artist and their distribution throughout the body of the painting.Preliminary investigations have shown that the stability of oil paintings is unaffected by the activation procedure. The inherently necessary radiation dose absorbed by a painting as a result of activation sufficient for autoradiography is of the order of 50 rads. Paintings subjected to absorbed doses one hundred times as great as the dose necessary for autoradiography exhibit no changes in color, hardness, flexibility and solubility three years after their original activation. 相似文献

ABSTRACT This article presents historical and scientific analysis, as well as the conservation treatment of a newly rediscovered Roman wall painting fragment, now in the collection of the Harvard Art Museums. Although the piece has not previously been published, it was among a group of fragments removed from a Roman villa near Boscotrecase in southern Italy, an area that has been key to the study of Roman wall painting and other decoration. Technical imaging confirms the use of painting techniques consistent with other high-quality paintings in the area. Materials analysis revealed a palette consistent with published findings of Roman wall paintings, including abundant use of Egyptian blue and green earth. Of interest was the use of Egyptian blue as an optical brightener in select white passages. Despite the high quality of the painting, no cinnabar was present, and all red passages were achieved using hematite. Multiple different white minerals were identified including calcite, aragonite, and gypsum. The widespread presence of gypsum is unusual and may point to alteration. 相似文献

Lapis Lazuli in an Enigmatic ‘Purple7rsquo; Pigment from a Thirteenth-Century BC Greek Wall Painting
《文物保护研究》2013,58(4):252-266
AbstractThis paper presents the first evidence of lapis lazuli or lazurite that was detected unexpectedly using micro-Raman spectroscopy during research to identify an enigmatic purple hue on the thirteenth-century BC Greek Bronze Age wall paintings from Gla. The lapis lazuli material was found as part of a mixture including a red iron oxide and an as yet unidentified purple staining material. Existing purple mixtures of that period are also discussed. The identification of lapis lazuli at Gla may prove to be the earliest known use of this pigment in buon fresco, in both Eastern and Western painting traditions. Furthermore, this precedes the next known use of the material as a pigment by 1800 years. The existence of this blue pigment is also discussed within the context of the blue pigment palette of the Bronze Age Aegean and eastern Mediterranean Bronze Age (3300–1100 BC), to show its use in relation to other blue materials and to demonstrate the technology and knowledge mastered by the artists who used this lazurite. 相似文献

One of the most important artistic circles in the first half of the fifteenth-century in Austria was the so-called ‘Older Villach's workshop’, founded by Frederic of Villach, a painter who was considered a master of fresco technique. A technical study was made of a number of wall painting cycles by the workshop of Frederic of Villach, first, to gain a broader knowledge of the painting techniques employed, and second, to allow comparison with a further group of wall paintings in Slovenia, which are stylistically related to this workshop and have been studied previously. Of special interest were artworks attributed to Frederic's son Johannes of Ljubljana and a number of other anonymous painters that show important similarities to Frederic's works. Samples of plasters and pigments were analysed by optical microscopy, scanning electron microscopy with energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction. An important difference in the composition of plasters was discovered between the selected artistic groups. The palette used comprised predominantly earth and other mineral pigments. The construction of the paintings from incisions and preparatory drawings to the final modelling is basically similar and shows workshop connections. The principal painting technique was a fresco. The results contribute to a wider knowledge concerning the materials and techniques employed in gothic wall paintings in the Alpine region and offer new information that can be used to inform the future conservation of these selected wall paintings. 相似文献

AbstractThe reasons for the often poor condition of Viceregal paintings and sculptures are examined. The conservation of four works is described, chosen largely because they had typical problems and would benefit from recently developed techniques. The treatments were: the preliminary lining of very cupped paintings, before using moisture to stretch the original canvas and allow the paint layer to lie flat again; lining badly torn paintings on a thin, semi-rigid, transparent support and using the old stretcher, in order to preserve the structure and aesthetic impression of the painting as much as possible; masking to protect susceptible fine lines against solvent action during cleaning; blending disturbing passages of the paint layer like blanching, irreducible stains, singeing and pentimenti into the colour scheme without overpainting; repairing broken pieces of sculpture with bamboo dowels. The study is accompanied by an iconographical discussion of colonial works of art. 相似文献

The subject of the research is an oil painting entitled Idyll created using an unusual technique. The painting layer was applied on canvas covered with photosensitive medium on which a photograph was developed. The results of the examination of Idyll in the context of its attribution to Henryk Siemiradzki (1843–1902) are discussed. Its atypical technology and the possibility of the artist having used the photographic technique are also considered. X-ray fluorescence spectroscopy, infrared spectroscopy, and scanning electron microscopy were performed to establish the technique and to characterize the pigments and materials used in the painting. The identified pigments and the information provided by analytical photography (UV, X-ray images) were compared with the results of the detailed examination of 56 of Siemiradzki’s oil paintings. Performed analyses revealed that the majority of the features identified in Idyll point to Henryk Siemiradski’s technique. 相似文献

ABSTRACT The forms of traditional Chinese painting and calligraphy are varied, including hanging scrolls, horizontal scrolls, screens, hand scrolls, and albums. Hanging scrolls are hung on the wall for display, but curling edges often appear on both sides of the hanging scroll. Various factors influence the deformation of paintings and calligraphy, such as temperature and relative humidity and the susceptibility of materials in scrolls as well as mounting techniques. The influences of structural components, such as tian gan (hanging rod), hanging rope, and di gan (lower rod) have received little attention. This paper focuses on the influences of tian gan deflection on the deformation of hanging scrolls, with the help of DIC (digital image correlation) visualization. Deflections of tian gan in two types of hanging methods were compared with a theoretical study. It was suggested that the influence of axial force was of great importance on the increase in deflection and bending moment. To reduce the bending of tian gan as much as possible, the vertical hanging method with appropriate position for the hanging rope should be chosen for mounting hanging scrolls. 相似文献

AbstractThe authors describe the application of TV holography, also known as electronic speckle pattern interferometry (ESPI), to the examination of wall paintings. The equipment usesfibre-optic illumination and a solid-state camera connected to a computer. Images made after the wall painting has been warmed slightly with an infrared lamp are compared with reference images; differences in the speckle pattern can be used to identify cracks and subsurface detachments. The system is robust and portable, allowing it to be used for the in situ investigation of wall paintings, including those exposed externally. It can also be used to monitor the condition of the work of art over time and to evaluate the success of any treatment. 相似文献

Moisture is a driving factor in the long-term mechanical deterioration of canvas paintings, as well as for a number of physico–chemical degradation processes. Since the 1990s a number of publications have addressed the equilibrium hygroscopic uptake and the hygro-mechanical deformation of linen canvas, oil paint, animal glue, and ground paint. In order to visualise and quantify the dynamic behaviour of these materials combined in a painting mock-up or reconstruction, we have performed custom-designed experiments with neutron radiography and nuclear magnetic resonance (NMR) imaging. This paper reports how both techniques were used to obtain spatially and temporally resolved information on moisture content, during alternate exposure to high and low relative humidity, or in contact with liquids of varying water activities. We observed how the canvas, which is the dominant component in terms of volumetric moisture uptake, absorbs and dries rapidly, and, due to its low vapour resistance, allows for vapour transfer towards the ground layer. Moisture desorption was generally found to be faster than absorption. The presence of sizing glue leads to a local increase of moisture content. It was observed that lining a painting with an extra canvas results in a damping effect: i.e. absorption and drying are significantly slowed down. The results obtained by NMR are complementary to neutron radiography in that they allow accurate monitoring of water ingress in contact with a liquid reservoir. Quantitative results are in good agreement with adsorption isotherms. The findings can be used for risk analysis of paintings exposed to changing micro-climates or subjected to conservation treatments using water. Future studies addressing moisture-driven deformation of paintings can make use of the proposed experimental techniques. 相似文献

AbstractThe collection of paintings by Velázquez in the Museo del Prado is important both because of the number of works — about 50 — and because of their quality and significance. It includes the Feast of Bacchus (The Drunkards), the Forge of Vulcan, Christ on the Cross, the Surrender of Breda (The Lances), the Fable of Arachne (The Spinners), Las Meninas and various royal portraits. Most of these works are in very good condition, which is essential for a proper study of the painter's technique and his development; in addition, since their source is the royal collection, they are well documented. Since 1982 most of the works by Velázquez in the Museo del Prado have been submitted to technical examination and to restoration. The technical studies included X-radiography, infrared reflectography, and analysis of the supports and materials, allowing us to establish the characteristics of each painting (technique, changes in composition, condition, history) and the development ofthe artist through the changes in his technique. Restoration consisted basically of consolidating the paint layers, moderate cleaning and the inpainting oflacunae. The only exception to the general good condition of the paintings was The Spinners, which presented a serious problem of craquelure and lack of adhesion in the paint layer. 相似文献

The technical study of wall paintings from the Buddhist temple complex at Nako, Western Himalayas, was one of the basic preconditions required for designing an appropriate conservation strategy. The complex, composed of four temples from the eleventh–twelfth century, offered a unique possibility to carry out a comprehensive research of technology and painting materials used in early and later western Tibetan Buddhist wall paintings as well as a comparative assessment with murals from other sites in the Western Himalayas. The study was based on extensive fieldwork and an integrated analytical approach comprising a wide range of non-destructive and micro-destructive methods. Answering the question of the coevality of paintings in the smaller temples with other original murals, the precise characterisation of binding media, the detection of the yellow dye gamboge and natural minerals posnjakite and brochantite identified for the first time in Himalayan murals, the clarification of technology of metal decoration, and the making of raised elements are some of the most exciting results which emerged from the research. 相似文献

SummaryA Roman wall painting of the first century AD, recently discovered in Rome, has been studied extensively, in situ, by non-destructive X-ray fluorescence (XRF) analysis. The coloured pigments, the medium and the plaster were all examined. The presence of potassium and calcium in all coloured layers demonstrates that the painting technique is of a type very similar to that used in Pompeian wall paintings, and described in the 1950s by Selim Augusti. In this type of wall painting, the pigments were dissolved in a lime/soap/water solution, the function of the soap being to mitigate the negative effects of lime on alkali-sensitive mineral-based colours. 相似文献

AbstractThe history, materials and technique of an early fifteenth-century wall painting, St Michael Weighing Souls, are described. The pigments are typical of mediaeval Spain but the methods by which they were applied show a sophisticated understanding of their optical properties. Complex mechanisms of deterioration in some areas of colour are discussed, together with the rationale, materials and methods used in the conservation treatment. 相似文献
