Reworking an Interior Sketchbook: The Conservation and Display of ‘Rød Og Blå’ Anamorphosis

This was achieved by conscious employment of the entire, often previously unused, wall surfaces as well as displaying works at various unconventional heights. Plans for the rehang coincided with the conservation treatment of more than 30 fragile works from the late 1970s by the influential Danish artist Albert Mertz (1920-90). These works like many others in the collection, challenge traditionally held ideas of artwork, including conventional display. Executed in modern synthetic paints, the supports of the rød og blå (red and blue) Anamorphosis consisted of various sizes and thicknesses of poster card, card and cardboard. The conservation policy that was devised, which involved liaising with curators and with the artist’s widow, emphasized safe handling, storage and, in particular, display of the works, bearing in mind that the artist had tended to use his wall space as a large, re-workable ‘sketchbook’. Lamination to thin Plexiglas and attachment to specially prepared walls using magnetic strips caused minimum interference in the integrity of the works and employed display principles faithful to those of Mertz himself.

Canvas Supports and Grounds in Paintings by C.W. Eckersberg

Such cracks are visible in 50 µm resolution x-radiographs and correlate with the occurrence of microcracks as well as more large-scale crack patterns in the surface of the paintings. They also explain the initiation of one type of crack formation and the subsequent propagation of the crack into the paint layers. An examination of 41 paintings by the Danish artist C.W. Eckersberg, dating from throughout his oeuvre, showed a variable prevalence of microcracks in 24 paintings. Some cracks were visible only in the x-radiographs while others could be observed also on the paint surface. In many cases, it was found that microcracks were incorporated into the larger crack pattern of the paint. The mechanical process underlying the genesis of microcracks is discussed, and a potential association with the stratigraphy of the grounds used in Eckersberg's paintings is proposed. 19th Triennial Conference 2021 Beijing PAINTINGS Canvas-related microcracks in Danish 19thcentury paintings To cite this article:
Proteomic identification of beer brewing products in the ground layer of Danish Golden Age paintings
Science Advances

This is highly valuable to plan conservation strategies and reconstruct the artwork’s history. In this work, the proteomic analysis of canvas paintings from the Danish Golden Age led to the confident identification of cereal and yeast proteins in the ground layer. This proteomic profile points to a (by-)product of beer brewing, in agreement with local artists’ manuals. The use of this unconventional binder can be connected to the workshops within the Royal Danish Academy of Fine Arts. The mass spectrometric dataset generated from proteomics was also processed with a metabolomics workflow. The spectral matches observed supported the proteomic conclusions, and, in at least one sample, suggested the use of drying oils. These results highlight the value of untargeted proteomics in heritage science, correlating unconvention...
