The use of ultraviolet and visible diffuse reflectance spectrophotometry as a preliminary technique in the investigation illuminated manuscripts is discussed. Because ancient are amongst most fragile precious artworks, characterisation materials used their decoration should be performed using non-invasive analytical methods. Ultraviolet with optical fibres (FORS) allows identification several colourants by illuminators, causing no damage or mechanical stress to artworks subjected analysis....
A paradigm using multispectral visible and near-infrared imaging spectroscopy is presented to semi-automatically create unbiased spectral maps that guide the site selection for in situ analytical methods (e.g. fiber optic reflectance X-ray fluorescence) order identify map pigments illuminated manuscripts. This approach uses low resolution of areas having same characteristics. demonstrated by analysis manuscript leaf Christ Majesty with Twelve Apostles (workshop Pacino di Buonaguida, c....

Two types novel hyperspectral cameras, one operating from visible near-infrared (VNIR, 400–900 nm) other...
Abstract A selection of 23 rare glass objects, mostly enameled, various provenance and age, from the 5th century BC to 19th AD including Western Islamic Middle Ages but with a focus on 16th–18th Venetian French ‘ façon de Venise ’ artefacts, have been studied on‐site at Sèvres museum or laboratory. The Raman signatures transparent opacified matrix enameled decorations are discussed compared those previously recorded ceramics stained glasses. parameters allow discrimination between 2 groups...
In situ analysis: Near infrared imaging spectroscopy (1000–2500 nm) is used to map the use of a fat-containing paint binder, likely egg yolk, in on work art for first time. The identification tempera 15th century illuminated manuscript leaf (Praying Prophet by Lorenzo Monaco) sheds light relationship between painters and illuminators can inform preservation decisions.
This paper presents the results of a study pigment-binder systems painted on parchment, both in form reference samples prepared laboratory, and medieval Renaissance illuminated manuscripts, by means contactless Fourier-transform mid-infrared spectroscopy (FTIR). The research is aimed at validating external reflection FTIR (ER-FTIR) as non-invasive method for identification paint binders works art parchment. Based systematic investigation undertaken attenuated total (ATR) ER mode, we discuss...

Abstract In this work, we report the results of in situ application micro‐Raman spectroscopy to analysis two historic painted objects: a 15th‐century illuminated manuscript and late 16th‐century portrait miniature. Both objects were unexpectedly found contain calomel (Hg 2 Cl ), intentionally used as white pigment. Calomel was widespread popular medicine until it fell out use at end 19th century due its toxicity, material called ‘mercury white’ is referred technical literature on painting....
Site specific, in situ techniques such as X-ray fluorescence (XRF) and Raman spectroscopy are commonly used to identify pigments on illuminated manuscripts. With both techniques, spectra usually acquired visually identified sites thought be representative of the mixtures for illumination. Such visual inspection may not always ensure an adequate representation pigment diversity. Here we report application multispectral (MSI) visible/infrared reflectance luminescence imaging spectroscopy,...

Infrared reflectography (IRR) remains an important method to visualize underdrawing and compositional changes in paintings. Older IRR camera systems are being replaced with near-infrared cameras consisting of room temperature infrared detector arrays made out indium gallium arsenide (InGaAs) that operate over the spectral range ~900 1700 nm. Two types becoming prevalent. The first is staring array having 0.25–1 Megapixels where or painting moved acquire tens individual images later mosaicked...
