“…The absorption bands at around 3445 and 1645 cm -1 in all samples indicated the presence of adsorbed water due to the long burial of the potsherds [38][39][40]. From the spectra of the samples (Table I), a very weak to weak absorption band present at 2984 and 2899 cm -1 may be assigned to the asymmetric C-H group indicating the presence of organic carbon in the sample [41]. In the region 1100-400 cm -1 , the vibration bands corresponding to Si-O, Si-O-Si, and Al-Si-O were detected in all the samples which may be assigned to feldspar and quartz.…”

The abundantly available mica flakes were added in raw materials to manufacture pottery in Central Peninsular India during the early Iron Age (700-300 BCE) for storage and glittering. The micaceous potsherds from the excavated megalithic site of Nagpur were studied for their composition, manufacturing techniques, microstructural features, microbial colonization, and estimation of firing temperature. The analytical techniques used were micro-XRF, FTIR, XRD, FEG-SEM, mercury porosimetry (MIP), and thermal analysis. The XRF and SEM-EDX data revealed that the potteries were coated with aqueous iron oxide on either surface for red hue and subsequently fired at an estimated temperature of 700-750 °C in a reducing atmosphere as determined by vibrational and mineralogical analysis. The X-ray microscopy and FEG-SEM images showed a grey color sandwich layer representing the original clay composition between iron oxide-coated red surface layers. MIP showed that the fine ware had a high porosity of 21-26% with a void ratio (e) of 0.28-0.36. The loosely adhered mica flakes influenced the strength and stability of the pottery. The 16S rRNA gene sequencing identified the presence of Bacillus velezensis within the round and elongated pits within the potsherds drawing nutrients from minerals.

“…Ceramic mixtures with a low calcite content of less than 2% are defined as noncalcareous, while clays that are rich in calcium can have up to 20% calcite, forming calcareous ceramics. The decomposition of CaCO 3 happens at relatively low temperatures to provide carbon dioxide and lime, which reacts with clay in the mixture [34,41].…”

Waste ceramic is produced from different sources and, if not reused, is often disposed of in landfills, contributing to the pressure on landfill capacity and potentially releasing toxins into the surrounding environment as ceramics break down over time. The waste can easily be crushed to the required sizes, which has interested many researchers. It has been used as a replacement for concrete constituents, including cement and aggregates. This offers a promising avenue for reducing the environmental impact and promoting sustainable construction practices by reducing the amount of energy consumed and resources required for concrete production, as well as the amount of waste being sent to landfills. This paper aims to provide a review of the use of waste ceramic in concrete. In essence, the paper is divided into several sections. The first section highlights the current environmental issues associated with concrete production and waste disposal. The second section deals with ceramics, its raw materials, production steps, and the different types of waste ceramic used in concrete. A literature review of the use of waste ceramic in concrete was included in the third section. The study reports different research on the use of waste ceramic and its impacts on the mechanical and durability properties of concrete.

“…The main mineral phases may be determined by several spectroscopic techniques such as Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) and also the elemental analysis performed by energy-dispersive X-ray spectrometry (EDS) of the samples. FTIR spectroscopic technique is a very helpful analytical method to determine the mineralogical composition of archaeological pottery samples [3][4][5][6][7]. XRD technique is specially applied in the analysis of pottery because the main mineral crystalline phases may be found [8].…”

Within the framework of a technological study of pottery production of Porunthal, Dindigul district of Tamil Nadu, India, the chemical composition and mineralogy of the 7 potteries of different varieties from that archaeological site were studied using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis-derivative thermogravimetry (TGA-DTG), and scanning electron microscopy coupled with energy dispersive spectrometer (SEM-EDS). The analytical data obtained from several analyses were used to determine the mineral transformations during firing, such as quartz, feldspar, and iron oxides (hematite and magnetite), firing temperature, and firing conditions. The results of all the techniques confirmed that all the samples were manufactured by the artisans locally with the same raw materials and also were fired at the same temperature.
