Research and Technical Analysis
The impact of modern scientific techniques into the conservation field has been impressive. It allows conservators to work with a much higher degree of certainty, precision, and to see beyond the naked eye, to see ‘through’ a work. Its principal objective is to analyse an artist’s painting techniques, assess damage and any previous restorations to establish a restoration strategy. It can also reveal whether a work is a forgery or a copy.
At ACI we like to stay at the forefront of the newest scientific techniques. For us, great restoration is the marriage of science, art and art history. Outlined below are some of the techniques we use :
Digital Infra-red Photography
This reveals the original drawings behind the painting and losses of paint.
X-Ray and Radiography
This allows a conservator to establish how a painting was composed based on different layers of absortion and the technique employed by the artist. It can also reveal a painting’s real origins and solve issues of attribution.
Pigment and Medium Analysis
Microscopic samples are taken for analysis and can be used to deepen the understanding of materials, technique and to date a work.
It is a key method to assess the different conditions of paint layers. By looking through a microscope it can reveal how the layers were applied and give insights as to how the artist worked and the exact nature of the materials used. The information gathered can then be combined with UV and X Ray to provide precise information on the object’s history and the artist’s technique.
This simple technique can be used to reveal layers, pigments, previous restorations and the techniques used by an artist (preparatory drawings….)
Whether it is UV, infrared or daylight digital, photography is a fundamental part of the restoration process as it is used before, during and after a work has been restored.
Equally, galleries, dealers, auction houses and the like will invariably use daylight digital images rather than original artwork to get an idea of the quality and condition of a piece. In order to retain complete control of this process ACI have a state-of-the-art equipment (Hasselblad) and an in-house photographic studio. This ensures colours are reproduced accurately and that all images are of the very highest professional standard.
Prior to starting major projects(large formats, murals, museum pieces….) we supply detailed Graphic Reports which highlight simply and graphically the techniques employed and the problems to address.
