Moreover, wax, eggs and [80]. identified, the presence of which can be due to earlier restoration workanimal glue have already been identified, the presence of that is due to prior restoration perform [80].Figure 1. The picture of Season in room 42 (the antechamber from the so-called 2-Hexylthiophene References erotic cubiculum) of Figure 1.

Insula del Centenario, Pompeii, Italy, exactly where sample 42/2 was collected.A paper has been published on Villa of your Papyri in Herculaneum, so that you can know the presence of an organic binder. The authors found egg, by implies of GC-MS, in some samples, where the pigment expected a secco strategy. They also investigated the presence of wax employed as superficial treatment options of the wall painting. The truth that they didn’t detect beeswax in all of the analyzed samples give additional Tropinone Protocol information that the encaustic method was not used for the realization with the wall paintings on the Vesuvian region [81]. An intriguing perform examined the wooden roof and ceiling in the Home in the Telephus Relief in Herculaneum. The target of this study was to assess the strategies utilized to decorate the wooden ceiling, employing a multianalytical method (SEM/EDX, FT-IR spectroscopy, GC/MS and Py-GC/MS). The outcomes showed that a tempera painting has been chosen. Egg was employed as binding medium, as confirmed by the evaluation on the proteinaceous fraction and by the presence of cholesterol. In only one sample, caseinAppl. Sci. 2021, 11,12 ofwas determined, in all probability employed as an adhesive. The paint layer was straight applied the wooden ceiling, with no a preparatory stratum. A motivating aspect of this paper is the fact that the authors argue that, primarily based on chemical investigations, this can be the initial time it has been possible to prove that egg tempera has been applied to decorate wooden architectural components [82]. Cunhighlights the fact that investigations of ancient Roman wall painting show the difficulty of efficiently extracting organic binders. The author considers that from time to time it can be deemed an affresco painting, because of the lack of outcomes obtained, when the organic binder could possibly be present, but not identified for purely analytical difficulties. The use of inappropriate extraction solutions for ancient paint supports may cause the transformation of some elements on the binder, making an incomplete characterization with the composition He pointed out that chemical analyses of Roman wall painting have identified other kinds of paint binders and that there’s a clear difference in between the results of 1 study group along with the other. These factors could be associated towards the difficulty of extracting ancient painting binders and, furthermore, the influence of microbiological contamination. The absence of data in most studies around the efficiency of extraction actions used in antique samples as well as the effect of microbial contamination may give rise to doubts about several of the benefits obtained [8]. Cunet al. (2012) studied eight samples of Roman wall paintings from 3 archaeological web pages in Spain applying complete attenuated reflectance Fourier transform infrared spectroscopy and GC-MS, in an effort to recognize organic binder. It was observed the samples featured beeswax and soap. These outcomes show for the very first time that Roman artists utilised in mural paintings.
