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
Accés obertThe 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
Accés obertA 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
Accés obertA 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
Accés obertA 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
Accés restringit per política de l'editorialThe 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
Accés obertLustering, 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
Accés obertEls 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
Accés obertResins 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
Accés obertMicro-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 ... -
