Analysis of pigments from Roman wall paintings found in Vicenza

Analytical study of the XIV century wall painting and lime mortars in the "St. George" church in Staro Nagoričane, Republic of Macedonia

“…Moreover, when the black sample was heated using a low Bunsen flame after it was placed on the platinum plate, the black color tends to disappear, indicating the presence of carbon (coal, soot) [4,26]. (a) XRF spectrum and (b) IR spectrum and its second derivative profile (inverted curve).…”

Use of Different Spectroscopic Techniques in the Analysis of Roman Age Wall Paintings

“…PIXE big detector spectrum in FIG. 4, shows the presence of sharp Fe peaks, and also the presence of As, rarely detected in red samples of the Venetia et Histria Region [14][15][16][17][18] . The presence of As is shown also in the XRF spectrum.…”

“…The EDS spectrum of the green sample show the typical elements, Ca, K, Fe, Al and Mg of the green earth pigments (celadonite and glauconite) [14][15][16][17] . In FIG.…”

“…Eight Roman age wall paintings samples, coming from: Vicenza [14][15][16] Pordenone, 17 and Verona 18 were analysed; the samples were: a red pigment superimposed to a yellow and a blue found in Pordenone; a brilliant red, a black and a green-blue found in Vicenza; a green and a red from Verona.…”

Nafion® as advanced immobilisation substrate for the voltammetric analysis of electroactive microparticles: the case of some artistic colouring agents

“…X-ray transmission images provide useful information on the metals used in an artwork, such as the nails connecting the wood panels of tempera paintings. Advanced spectroscopic techniques, such as X-ray fluorescence [2][3][4][5], proton-induced X-ray emission (PIXE) [6,7] and fibre optics reflectance spectroscopy, are used for the non-destructive identification of pigments [8]. In this field, a wide variety of analytical techniques should be used, since each one of them gives partial information to answer questions that are normally very complex.…”
