The “Historical Materials BAG”: A new facilitated access to synchrotron X-ray diffraction analyses for cultural heritage materials at the European Synchrotron Radiation Facility
(2022-03-20)
Article
Open AccessThe European Synchrotron Radiation Facility (ESRF) has recently commissioned the new Extremely Brilliant Source (EBS). The gain in brightness as well as the continuous development of beamline instruments boosts the beamline ... -
Carbonation of fresco mural paintings with a dolomitic mortar
(2022-07)
Article
Open AccessA fresco painting has a calcium carbonate binder produced as result of the carbonation process of a lime paste. The reaction environmental conditions are similar to those of bio-mineral formation where an amorphous cal-cium ... -

(2020-05-01)
Article
Open AccessA fresco painting has a calcium carbonate binder produced as result of the carbonation process of a lime paste. The reaction environmental conditions are similar to those of bio-mineral formation where an amorphous calcium ... -
Insights into the composition of ancient Egyptian red and black inks on papyri achieved by synchrotron-based microanalyses
(2020-11-10)
Article
Open AccessA hitherto unknown composition is highlighted in the red and black inks preserved on ancient Egyptian papyri from the Roman period (circa 100 to 200 CE). Synchrotron-based macro–X-ray fluorescence (XRF) mapping brings to ... -
Markers, reactions, and interactions during the aging of pinus resin assessed by Raman spectroscopy
(2017-04-28)
Article
Restricted access - publisher's policyThe resin extracted from the species of the Pinus genus (Pinaceae family) is a widely used material. Primarily, resins are made up of two types of diterpenoids: abietanes and pimaranes. Their composition changes with aging, ... -
Microanalytical study of luster glazed gilding and silvering from Baroque altarpieces
(2018-03-01)
Article
Open AccessLustering, a technique which involved the application of coloured translucent glazes over gilding and silvering was widely used to enrich and decorate altarpieces in the Baroque period. The decorations consist of a micrometric ... -

(2015-07)
Article
Open AccessEls segles XVII i XVIII són el moment de màxim esplendor a tota Europa en l’ús de les colres de colors. La tècnica de les colres de colors sobre fulls d’or o plata de l’època barroca està poc estudiada des del punt de ... -
Ageing of resin from Pinus species assessed by infrared spectroscopy
(2016-04-06)
Article
Open AccessResins obtained from Pinus genus species have been widely used in very different fields throughout history. As soon as the resins are secreted, molecular changes start altering their chemical, mechanical and optical ... -
Low molecular weight organic acid salts, markers of old fungi activity in wall paintings
(2016-02-21)
Article
Open AccessMicro-Infrared Spectroscopy (mSR-FTIR) and X-ray diffraction (mSR-XRD) with synchrotron light, Gas Chromatography/Mass Spectrometry (CG/MS), Optical Microscopy (OM) and Scanning Electron Microscopy (SEM/EDS) were used ... -
Optimal Sample Preparation for the Analysis of Micrometric Heterogeneous Samples
(2015-05-29)
Article
Open AccessPrecise microanalytical techniques are essential in many fields such as cultural heritage materials, showing complex layered microstructures containing a wide range of materials of diverse nature and hardness. Noninvasive ... -
Micro infrared spectroscopy discrimination capability of compounds in complex matrices of thin layers in real sample coatings from artworks
(2015-01)
Article
Open AccessThe presence of coating on manufactures either to protect them from the environment, or to give them specific properties—as well as simply to change their aspect—has been shown to be a constant practise throughout history. ... -
Determination of hexavalent chromium in leather by ion-exchange chromatography
(2014-09-01)
Article
Restricted access - publisher's policyThe determination of traces of hexavalent chromium in leather and in leather consumer goods is carried out by ion-exchange chromatography. Samples are extracted at pH7.5-8 with a phosphate buffer, according to the method ...
