Fading into the background: the dark space surrounding Vermeer’s Girl with a Pearl Earring. The combination of MA-XRF and RIS offer the ability to determine the distribution of the pigments that had been identified in cross-sections. The spectrally broad fluorescence from the varnish, lead white, and other materials within the paint (see above) can be absorbed by ultramarine. Scans were carried out at 50 kV and a current of 600 µA, with a 400 µm step size, and a dwell time of 125 ms. The catalog comprises an essay and checklist with reproductions of the exquisite works in the show. 5e inset) maps to areas having the largest amount of tin (Fig. In the late 16th century, the prepared stone could be obtained in small quantities through Found inside – Page 152She grow rich . ” had been standing by the open window al “ You're utterly devoid of conscience , Doromost since Marseilles , drenching her senses thea , ” said I severely .

By moving the measuring head on the XY-motorised stage at a constant speed (3.2 mm/s), the painting is scanned pixel by pixel, line by line. Conservation, examination, and interpretation. In the darker areas, the MA-XRF Pb M map shows less lead, which is consistent with the RIS ‘red’ endmember (Fig. Appendix II: technical reexamination of the Feast of the Gods. However, inspection of the three types of emission spectra in the jacket (Fig. Ultramarine Blue. This indicates that the pigment was obtained from lapis lazuli, and it is not the synthetic material called ultramarine blue, which was first synthesised in 1828. 8e. Lead white is also present in the border of the headscarf, based on the NIR absorption at 1449 nm in the reflectance spectra, as well as the lead distribution in the MA-XRF Pb M map. CAS © 2021 BioMed Central Ltd unless otherwise stated. Modern Geol. A filter (460–540 nm bandpass filter) placed in front of the projection lens further limited the excitation spectral band from 460 to 532 nm. However, the darker folds within the cartridge pleating, as well as the very back of the jacket, is mapped by the ‘red’ endmember (Fig. Reference spectra of known samples of lazurite and cinnabar are also shown for comparison purposes. JKD and KAD collected and processed the RIS and FIS image cubes and made the figures. Automatic registration and mosaicking of technical images of Old Master paintings. The imaging spectrometer has a spectral sampling of 2.5 nm, and produces image cubes with 1024 by 1024 spatial pixels and 280 spectral channels. Vermeer studies: studies in the history of art 55.

This article considers the local Florentine history of artisanal knowledge regarding the preparation of ultramarine blue from the lapis lazuli stone. In contrast, modern pigments such as Prussian blue and lead chromate (also known as chrome yellow) were detected on stucco fragment A.10-1913 (see Figure 3). This gives an image that is a blotchy khaki colour, where the variation in the false-colour ranges from yellow-green to brown, and smaller regions are brighter or darker. 8c. Appl Phys A. Since the fluorescence emission is modelled as a linear function, to generate the pure ‘endmembers’, a scaled version of the spectrum with decreasing fluorescence (‘green’ dashed spectrum, Fig. A tutorial where I show how to quickly paint up an Ultramarine space marine.http://itslikewatchingpaintdry.blogspot.ca/2013/09/how-to-paint-ultramarines.html.

PubMed Google Scholar. irregular size and shape, broken edges and non-uniform colour. Cookies policy. The analysis of pigments and materials found on these stucco panels from the Alhambra Palace in Granada, Spain, gave sufficient clues to hypothesise that one of the panels was not from the 14th century, as originally thought. The ‘red’ and ‘blue endmembers were calculated by subtracting off a scaled spectrum of the component with slowly decreasing emission, shown with a ‘green’ dashed line. Dooley KA, Conover DM, Glinsman LD, Delaney JK. Both of the emission shoulders appear to be riding on an overall background that shows a decreasing emission intensity with increasing wavelength, described by the ‘green’ spectrum in Fig. 6e). New Haven: Yale University Press; 2017. p. 64–83. 7c). Manage cookies/Do not sell my data we use in the preference centre. The same method for producing the apparent reflectance image cubes was followed: a dark image cube was subtracted from the raw fluorescence image cube. Vermeer and the masters of genre painting: inspiration and rivalry. OH), associated with yellow ochre [10, 11]. 8f) revealed distributions that suggest the presence of diagonal lines—possibly depicting a curtain—on the right side of the painting, hypothesised to be from modelling with lead white present in the glaze. Springer Nature. The restoration of “Woman in Blue Reading a Letter” by Johannes Vermeer. Conover DM, Delaney JK, Loew MH. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. The conversion of the raw image cubes to apparent reflectance was done using a standard protocol. Gifford EM, Glinsman LD. Verslype I. Separating two painting campaigns in Saul and David, attributed to Rembrandt, using macroscale reflectance and XRF imaging spectroscopies and microscale paint analysis. Consistent with the MA-XRF lead (Pb M) map (Fig. 7e) was subtracted from the emission spectra associated with the 620 nm and 707 nm features to create endmember spectra (Fig. Groen K, van der Werf ID, van den Berg KJ, Boon JJ. A tutorial where I show how I airbrushed, painted and weathered an Ultramarine Rhino.http://itslikewatchingpaintdry.blogspot.ca/2013/11/ultramarines-rhino-fi. Use and limitations of second-derivative diffuse reflectance spectroscopy in the visible to near-infrared range to identify and quantify Fe oxide minerals in soils. @blakley_b on Twitter!acidpitbull187 On Twitch! 5d) having a weak 1449 nm absorption feature. For example, when pigment analysis is carried out on a museum object, it can reveal the presence of date-marker compounds, i.e. Gypsum, and in one instance, calcite were detected in the stucco mortar, and traditional materials such as lazurite, cinnabar, and carbon black were detected on stucco fragments supposedly still covered by the original decoration. In visible light, these areas have a cooler, somewhat ruddy blue-green colour. Lucia Burgio https://doi.org/10.1007/s00339-008-4474-6. The colour of the spectra corresponds with the coloured ROIs shown in the false-colour image in Fig. Extraction of endmember spectra that described the background using multivariate methods was not successful and so other methods were used to document the degree of variation in the reflectance spectra. Clark, University College London, for kindly granting access to his Raman spectrometer for pigment analysis. To explore whether the dark underlayer is the only contributor to the observed NIR reflectance, the NIR spectral region from 1000 to 1680 nm in the RIS image cube was examined to determine if the reflectance varies over this range of longer wavelengths.

As expected for stuccoes, gypsum and occasionally calcite were detected in the mortar samples. 5a) shows that the bottom edge of the headscarf has a border, where the colour ranges from blue to yellow-green. 8b) using the reflectance values in the visible spectral region at 450 nm (blue channel), 504 nm (green channel) and 608 nm (red channel). These emission spectra were generated by first selecting spectra from areas of the emission cube where the above spectral features were strong: the 620 nm shoulder from the lips, the 707 nm shoulder from the blue headscarf, and the decreasing fluorescence from the front of the neck. The latter hypothesis is supported by observations collected during the conservation treatment of the stucco fragments. The paintings conservation department at the Mauritshuis helped with logistics.

Herit Sci. Complementary standoff chemical imaging to map and identify artist materials in an early Italian renaissance panel painting. 2), identified as a red lake. UV-Vis-NIR reflectance spectroscopy of red lakes in paintings. AvL performed the MA-XRF data collection and made the element maps. The region of the figure was masked; c average reflectance spectra from five regions of interest shown in b; d NIR reflectance image averaged from 725 to 925 nm; e image showing difference in reflectance between two NIR spectral regions: 1600–1680 nm and 1000–1200 nm; f MA-XRF map of lead (Pb M) (thresholded to emphasise the background). Mapping the pigment distribution of Vermeer’s Girl with a Pearl Earring. When mercury(II) sulfide (HgS, also called vermilion or cinnabar) was detected and identified by Raman microscopy, its particles examined by polarised light microscopy showed an irregular distribution of shape and size, as well as the presence of striations on some of the biggest . Two of the ROIs (‘green’, ‘red’) have a reflectance maximum at ~ 525 nm that indicate a green-coloured paint (Fig. If you were thinking of giving a gift to help us on our way,a gift of money in a card would really make our day!

The endmember with a green-shifted reflectance maximum (‘green’ spectrum, Fig. 7b). The NIR reflectance image cubes were collected using two 150 W halogen 3000 K lamps (Osram) in a reflective housing with a diffusor (Lowel ViP Pro-Light). 7d) better inform the interpretation of the false-colour image. Cinnabar, Table 1 Materials identified on the Alhambra stucco panels. The pigment maps show that Vermeer made extensive use of yellow ochre and ultramarine to paint the headscarf as well as the jacket, and he added a red lake to the areas of the jacket meant to be in relative shadow.

Although some of the pigments detected here were known previously, the spectral imaging modalities used in this study provided a better understanding of their distribution. 6b). @blakley_b on Twitter!acidpitbull187 On Twitch! This procedure corrected for non-uniformity of the illumination and the effective variation in the throughput of the camera and converted the fluorescence emission image cube to ‘relative spectral radiance’. CAS 2019;7:69. https://doi.org/10.1186/s40494-019-0311-9. Melanie Gifford, Lisha Glinsman and Barbara Berrie for providing invaluable advice during the analysis of the various data sets. 5e inset) maps to areas that overlap with moderate amounts of tin (Fig. a Visible light detail. The range of brightness in this spectral range is ~ 2 to 4%. https://doi.org/10.1186/s40494-019-0348-9, DOI: https://doi.org/10.1186/s40494-019-0348-9. In this paper, visible-to-NIR RIS (400–1680 nm) was used to examine the colour properties of the glaze across the painting surface by examining the variation in the reflectance spectra in the visible spectral region, as well as in the infrared region. One spectrum displayed an emission shoulder near 620 nm (‘red’ spectrum, Fig. [6]—appears yellowish with transparent blue spots. Collected from the entire web and summarized to include only the most important parts of it. 7e) maps strongly to the yellow and blue parts of the headscarf, as well as to the regions of the front lit side of the jacket that are rich in ochre (Fig. Privacy When mercury(II) sulfide (HgS, also called vermilion or cinnabar) was detected and identified by Raman microscopy, its particles examined by polarised light microscopy showed an irregular distribution of shape and size, as well as the presence of striations on some of the biggest particles. 6f), but only the front (lit) side contains lead (Pb L) (Fig. Based on the deep red emission wavelength shown in the false-colour image (i.e. https://doi.org/10.1039/c3an02094k. This 'terminus post quem' derives from the fact that Prussian blue was first synthesised in 1704, but it was not commercially available until the 1720s; on the other hand lead chromate, also known as chrome yellow, was first synthesised at the beginning of the 19th century. Indigo was found throughout the background, and small green areas (i.e. Herit Sci. 1998;46:528–36.

[6] analysed cross-sections to determine the stratigraphy of the background: a black underlayer and a glaze. 2019;7:102. https://doi.org/10.1186/s40494-019-0344-0. Cross-sections taken from the back of the jacket contained yellow ochre, ultramarine, black, and a small amount of red lake [6]. An exposure time of 150 ms per spatial-line was used to collect the 1024 lines in one image cube. In: Roy A, editor. One of the fragments (A.10-1913) also shows traces of synthetic, wet-process vermilion, characterised by uniformly sized, small, rounded particles. Follow the Channel! The white diffuse reflectance standard was used to confirm little light leakage from the excitation light was collected. The two data cubes were exported as raw files, and element maps were made and stitched using PyMca and Datamuncher software [24]. These features indicate that the red pigment is either of mineral origin, in which case it is more accurate to refer to it as cinnabar, or it is of synthetic origin, by means of the so-called dry process. In particular, the distribution of a red lake pigment in the Girl’s face and jacket has now been mapped. Herit Sci. These three endmember spectra were used to perform linear unmixing, which produces three images whose intensity values are proportional to the amount of the endmember present. https://www.ndt.net/article/art2008/papers/199Bisulca.pdf. https://doi.org/10.1346/ccmn.998.0460506. 5e). 2015;119:1567–75. The cross-sections and maps suggest that Vermeer’s pigment mixtures were well thought out, and that he intended that they create a specific effect.
