A study of the artistic corpus of red cave paintings in El Buxu cave (Cangas de Onís, Asturias, Spain)
(Elsevier, 2022-09-25)
El Buxu cave, which is located in the village of Cardes (Cangas de Onís, Asturias), has been studied since the
1980s, with multiple excavations taking place inside the cave. This work has uncovered a complete artistic
corpus, ...
Unraveling the role of the thermal and laser impacts on the blackening of cinnabar in the mural paintings of Pompeii
(Springer, 2022-10-27)
The blackening of red cinnabar (α-HgS) pigment has traditionally been explained by its conversion into black metacinnabar (β-HgS). Scarce is however the scientific evidence that supports this hypothesis in polychrome ...
Chemometrics and elemental mapping by portable LIBS to identify the impact of volcanogenic and non-volcanogenic degradation sources on the mural paintings of Pompeii
(Elsevier, 2021-05-03)
Crystallization of soluble salts is a common degradation phenomenon that threatens the mural paintings of Pompeii. There are many elements that contribute to the crystallization of salts on the walls of this archaeological ...
When Red Turns Black: Influence of the 79 AD Volcanic Eruption and Burial Environment on the Blackening/Darkening of Pompeian Cinnabar
(ACS, 2021-11-24)
It is widely known that the vivid hue of red cinnabar can darken or turn black. Many authors have studied this transformation, but only a few in the context of the archeological site of Pompeii. In this work, the co-occurrence ...
Elucidation of the Chemical Role of the Pyroclastic Materials on the State of Conservation of Mural Paintings from Pompeii
(Wiley, 2020-10-16)
Pyroclastic strata have always been thought to protect the archaeological remains of the Vesuvian area (Italy), hence allowing their conservation throughout the centuries. In this work, we demonstrate that they constitute ...
A Non-Invasive In Situ Spectroscopic Analysis of Cinnabar Minerals to Assist Provenance Studies of Archaeological Pigments
(MDPI, 2023-01-23)
This study presents a non-invasive in situ methodology based on the use of portable elemental (energy dispersive X-ray fluorescence spectroscopy, EDXRF) and molecular (Raman spectroscopy) spectroscopic-based instrumentation ...
Raman imaging to quantify the thermal transformation degree of Pompeian yellow ochre caused by the 79 AD Mount Vesuvius eruption
(Springer, 2019-11-07)
Most of the wall paintings from Pompeii are decorated with red and yellow colors but the thermal impact of 79 AD MountVesuvius eruption promoted the partial transformation of some yellow-painted areas into red. The aim of ...
Secco painting technique revealed in non-restored Pompeian murals by analytical and imaging techniques
(Elsevier, 2023-09-15)
The fresco technique appears to have been widely used on Roman mural paintings. The close observation of many of such murals suggests, however, the application of a secco technique over the fresco background. In this work, ...
