“…That appears in Figures (5a, b, c). The interpretation of the mineral identification results was confirmed by the X-ray diffraction analysis [11,12]. The result obtained by SEM-EDX analysis revealed the basic technologies related to obtaining pottery and ceramic objects, as well as the type of clay mineral components [20].…”

“…Moreover, important technological information is provided by the mineralogical composition that relates to the manufacturing process and firing. Furthermore, the characterization of artifacts such as shape dimensions, binders' aggregate ratio, and additive components affect the physical properties of the body vessel [11,12].…”

“…DTA provides important information regarding the crystalline structure of the target compound and the level of hydration of inorganic salts. Through DTA, there is a noticeable decrease in weight in the pottery samples [12]. The estimated firing temperatures of the pottery vessel are ascertained through the application of differential thermal analysis; the thermal transformation in the constituent mineral of clay is considered irreversible [16].…”

“…Samples investigation in reflected light conditions is considered to be a method of digital documentation. In addition, it shows the petrographic structural features and the deterioration forms [11,12]. The vessel body matrix contains inorganic additives like big grains of quartz (silica) and grog (grinding fired pottery) powder, in addition to straw as an organic temper.…”

This work aims to investigate a pottery vessel from eastern EIN-Shams, Egypt, lying in sandy soil from citizen lands, returning to the New Kingdom-Egypt. This pottery vessel was covered with white material from inside and outside. In terms of origin, this vessel is made of buff-colored clay; it has big pores, many cracks, and large missing areas filled with that material, with an uneven surface texture, that strongly bonds with the body pores, and shrinks away from the edges in some areas, in this way obscuring the original surface. In this respect, several physicochemical investigations in terms of chemical composition, physical properties, and nature of this white material were performed, to analyze the influence of it on the ancient pottery vessel. The analytical methods used in this research were USB digital microscopy, X-ray diffraction (XRD), scanning electron microscopy coupled with energy dispersive X-ray (SEM-EDX), and differential thermal analysis (DTA). The results of the USB digital microscopy showed the presence of gypsum crystals, large, flaked pottery surfaces, and quartz. SEM-EDX revealed the presence of organic fibers, chloride salts in a significant percentage, iron, and aluminum oxides. XRD investigation emphasizes the presence of gypsum and sodium chloride salts. DTA results revealed that the firing temperatures of the pottery vessel range between around 750-800°C.
