Analysis of the constituent materials of 19th century paintings attributed to Louis-Auguste Moreaux belonging to the Historical Museum of Santa Catarina – Florianópolis, Brazil

Characterization of the Alphabet Reform Painting

“…Infrared and UV authentications were as described in earlier reports (13)(14)(15)(16)(30)(31). Ambient light photograph of the oil painting was taken using a Canon 5D Mark III camera.…”

“…The successful restoration of artworks requires an in-depth analysis of the pieces. For instance, with the analysis of old paintings so much information can be attained such as the pigments used in the piece of art and changes that may occur in these pigments over time (1)(2)(3)(4)(5)(6), organic and inorganic substances (7)(8)(9)(10)(11), the binders (12)(13), the areas with retouches or patches on these pieces, the areas with varnish, structural deteriorations (such as cracking, flaking, peeling, and tearing) (14)(15), painting technique of the artist (16) and the types of the varnish (17)(18)(19) or the canvas that were used (such as silk, linen, hemp, cotton, jute) (20) which are of great importance for the restoration of these paintings. One can even have an idea about the palette of the artist given that he or she has the chance to analyze several pieces of art that belonged to that artist (21).…”

“…As a result of FTIR analysis, they found carbonates, sulfates, alumina silicates, iron oxides, and Prussian blue as pigments and they found that an oil-based binder was used. According to EDX results, Pb element was found in all samples (15). Milene Gil et al, studied Jose de Escovar's panel and mural painting by FTIR, SEM-EDX and technical photography (ultraviolet fluorescence-visible-Infrared) methods.…”

Analytical Investigation of Jiatang Scroll Paintings in the Seventh Year of the Guangxu Era

“…Mineral pigments have been widely used in ancient paintings, so their analysis has been particularly important in the conservation of historical and cultural heritage. Costa et al analyzed the materials of Louis-Auguste Moreaux paintings through a series of methods-the elemental composition of each pigment was identified by using SEM-EDS, and the molecular characteristics of the adhesives and pigments were analyzed by applying FTIR spectroscopy [23]. The high molecular weight compound, that is, the adhesive, was characterized by employing pyrolysis gas chromatography-mass spectrometry With the aim to (i) understand the technological and scientific level developed at that time and (ii) optimize future conservation and restoration actions for this kind of object, it is necessary to analyze the painting's ontology, which includes the identification of its fibers, pigments, and binding materials using modern material analysis and characterization techniques.…”
