The Effect of Firing Temperature on the Elemental Characterization of Pottery

Alteration and Contamination of Archaeological Ceramics: The Perturbation Problem

“…The LOI value incorporates several terms: the volatile elements (Cogswell et al, 1996) and, especially, certain elements such as hydrogen, oxygen and carbon that are usually not determined and that are related to the organic matter, the compositional water of primary phases and anions such as CO 3 2-, which are present in the original paste. This process, which is not a perturbation operation as defined in this paper, can actually be modelled as a perturbation induced by firing temperature during the transformation process from paste to fabric.…”

Investigation of Islamic ceramics from Tell Tuneinir using X‐ray diffraction

“…The detailed mineralogy of ceramic samples depends on the chemistry of the starting clay recipe and firing temperature, with additional roles played by the length of time the ceramic was fired and the amount of oxygen in its firing environment. For a discussion of chemical changes undergone by pottery during firing, see Cogswell et al (1996). Furthermore, the material properties of the ceramic are dominated by its mineralogy.…”

El análisis composicional en el estudio de la producción y distribución de la cerámica prehispánica

“…En cuanto a la estructura y composición química, la variación es inevitable, pues las altas temperaturas producen cambios mineralógicos y microestructurales en la matriz de arcilla de la pasta. Aún así, los experimentos indican que la mayoría de elementos químicos no se volatilizan significativamente durante la cocción, con la posible excepción de arsénico, azufre, bromo y cloro, cuyo punto de ebullición es relativamente bajo (Rye & Duerden, 1982;Kilikoglou et al, 1988;Storey, 1988;Cogswell et al, 1996;Schwedt et al, 2004). Los cambios ocasionados por el impacto térmico generalmente no afectan a la mayoría de las inclusiones minerales en la pasta, por lo que su identificación por el microscopio petrográfico resulta confiable.…”
