Since its introduction to Britain, the method has evolved and adapted, most recently owing to the absence of MS2A resin. Laropal A81 has been used as the replacement isolating varnish. However, the physical properties and handling differ from MS2A. The typical diluent used at the HKI for Laropal A81 varnish is a 50:50 mixture of Shellsol A100 and Shellsol D40, however, when used as the isolating resin over an area of retouching this mixture could disrupt lower tempera layers. To remedy this, the diluent was changed to cyclococtane, an aliphatic hydrocarbon. Cyclooctane benefits from being less toxic compared to the aromatic hydrocarbon Shellsol A100 and can be manipulated more on the surface before the activation of lower Laropal A81 layers becomes problematic. Laropal A81 solubilized in cyclooctane was successfully used as the isolating resin for egg tempera retouching and offers promise for a variety of varnishing scenarios and retouching. This paper demonstrates this adapted method of egg tempera retouching through a case study of a 16th-century panel painting with large losses perfectly suited to this method.

This technique appeared in France in the decade of the 1860s, spreading all over Europe with great rapidity, and with a remarkable impact until the beginning of World War II. The decoration with hydraulic mosaic is based on the use of tiles made of compressed cement, adorned with intense colours and a glossy appearance. After been used for more than a century, many of these decorations are in need of an immediate intervention. As they are serialized and mass-produced elements, their volumetric and chromatic reintegration becomes easier. Non-interventional procedures are not usually acceptable, as they often have pavement function. In this work, four different restoration techniques have been compared. Starting from inorganic binders, we have proposed 1) white cement / silicate mineral paint; 2) acrylic resin / paint and 3) epoxy resin / paint. Last, reintegration tests were made on marble stucco using a combination of plaster, pigments and animal glue. The results of these four systems were compared with the ones obtained from the traditional hydraulic mosaic, paying special attention to gloss, hardness, and porosity. As the goal is to choose the most appropriate technique applied to Cultural Heritage, its behaviour was tested through two accelerated aging tests. On one hand, a group of test samples have been exposed to the penetration of salts by capillarity, very common in pavements. On the other hand, the samples were placed in a climatic chamber with the aim of accelerating its aging, exposing them to humidity, heat and UV radiation. These tests have made possible to know the potential of each of these materials and their suitability for volumetric and chromatic reintegration.","PeriodicalId":115079,"journal":{"name":"6th International Meeting on Retouching of Cultural Heritage.

The central region of the city is made up of a set of buildings from the eclectic period that share space with modern buildings around the city's main square – Rui Barbosa Square. This square underwent several changes over time, highlighting the weaknesses in the construction of a heritage landscape in this territory, which supports collective memory. That said, we are interested in the contemporary transformations carried out in this region, which are related to both the market logic and the regulations regarding the clearing up the facades of historic buildings, such as the removal of advertising boards from stores. These reforms introduced new colors to the region, raising questions about the criteria (or lack thereof) for chromatic definition. The appeal to the use of strong colors without surveys or appropriate restoration techniques generates noise in the urban landscape. In this sense, we can ask ourselves if the advance in the promotion of heritage built by the public authorities can result in a tendency to trivialize the urban set. Specifically in this text, we will focus on the analysis of trivialization processes in urban sets of historical interest from the chromatic aspect, using comparative analyses, with structure analysis keys for the development of an initial critique of the cultural heritage in Uberaba.

Synthetic poly-2-ethyl-2-oxazoline based stucco (Aquazol®) has been one of the latest additions with good results in the filling of paintings on canvas. The main objective of this research is to determine the properties of Aquazol® 200 based filler as a texturing filling with respect to its workability and its mechanical behaviour in relation to the structural stability of different textile substrates. To this end, two case studies have been used as a starting point, both of which share the need to find a stucco that does not add moisture to the canvas and that can reproduce the texture of the painting layer. In the experimental part, 18 mock-ups were made reproducing the pictorial surface of each work, as well as the restoration treatments of their supports. These were subjected to accelerated ageing to qualitatively analyse the stability of the filling before and after. After testing, it was found that Aquazol® 200 has excellent qualities for levelling and texturing gaps on moisture-sensitive substrates. The good ability to reproduce brush grooves, small impasti and smooth surfaces is noteworthy. On the other hand, a satisfactory result was not achieved on very pronounced impasto, requiring further study.","PeriodicalId":115079,"journal":{"name":"6th International Meeting on Retouching of Cultural Heritage.

The radical changes in the intended use of the environment during the 19th century, associated with the destruction that occurred during WW2, left indelible wounds on the painted artefacts. In particular, the panels have undergone repeated treatments such as to conceal, in some cases, the 18th century paintings, creating a strong visual discontinuity. The pictorial activity included diversified technical solutions, modulated according to the specific problems encountered: small retouching alternated with extensive reconstructions based on historical photographic documentation and on direct comparison with the decorative elements of the most preserved panels. In compliance with the conservative history of the artefacts an overall recovery project was developed aimed at the search for a new aesthetic unit capable of coherently communicating with the remaining fixed furniture and mobile environment.
