“…In samples 5-2-1 and 5-2-3 even gehlenite (Ca 2 Al[AlSiO 7 ]) could be observed, which is peculiar to the fired pots (gehlenite appears at 800°C). [9] The moderate presence of 10 Ǻ phases in items 5-2-1, 5-2-2 and 5-2-4 could be attributed to their incipient re-hydration during the burial.…”

“…Absorption frequencies were assigned considering the available literature data referring to the most common clay mineral components and previous investigations carried on (mainly ancient) ceramic samples [9][10][11][12][13][14][15][16][17][18][19]. Infrared spectroscopy is a sensitive monitor of thermal processes (dehydration, dehydroxylation, redox transformations) occurred during the firing of clay minerals.…”

ABSTRACT. Five representative potshards collected from the Tăşnad-Sere C 52 archaeological site were investigated in order to evaluate the occurring differences of the raw materials used and the technology applied. The structural and compositional differences shown by petrographic analysis (optical microscopy /OM/ and XRD) and FTIR spectroscopy data indicate that according to both the raw materials composition (clay sediments and temper) and the pottery technique the samples studied form two distinct groups.

a Two hybrid coatings synthesized by using alkoxysilanes as precursors in a sol-gel process, differing from each other in terms of the organic components in alkoxysilanes, have been developed to improve the water repellent properties of base paper. The sol-gel-coated base paper samples were characterized by scanning electron microscopy, atomic force microscopy, confocal laser scanning microscopy, X-ray photoelectron spectroscopy, time-of-flight secondary ion mass spectrometry, and contact angle measurements. The sol-gel coatings were found to clearly change the surface properties of base paper. Thin coating layers were formed on base paper surfaces. The topographical data indicated the formation of discontinuous thin films; the time-of-flight secondary ion mass spectrometry analyses confirmed that the coatings were covering the fibres but only partially covered the fibre-fibre intersections. Water and the subsequent heat treatment used as a reference treatment reduced the surface roughness and porosity and slightly changed the surface chemistry of the base paper. The wettability and absorptivity of base paper was clearly reduced by the applied coatings.

“…This mechanism concerns the breakage of chemical bonds as a consequence of the temperature-dependent movements of the cellulose molecules and their constituent atoms. Deterioration of paper-based materials is also due to air pollution, biological attack and the presence of microorganisms like bacteria and fungi [2,[7][8][9][10].…”
