Abstract
On the influence of drying and firing of clay on the formation of trace element concentration profiles within pottery
A Schwedt
Hans Earl of Halsbury
495 - 509
On experimentally fired briquettes made of five chemically and mineralogically different clays, trace element concentration profiles from the centre to the surface of the briquettes were measured by neutron activation in order to examine if drying and firing of the clays lead to a mobilization and subsequent migration of single components within a sherd. Mineralogical changes during firing were determined by X-ray diffraction. Generally, no such migration could be found. For two clays, arsenic was lost from the briquette during firing, forming non-constant concentration profiles. If NaCl is present in the clay paste, sodium migrates towards the surface. Additionally, in the special case in which the presence of NaCl coincides with that of calcite, the heavier alkali elements evaporate, forming significant concentration profiles within the sherd.
Modelling changes in mollusc shell internal microstructure during firing: implications for temperature estimation in shell-b...

Firing experiments were carried out on a clay containing naturally occurring fragments of mollusc shell. The transformation and/or decomposition of mineral phases with temperature was monitored by thermal analysis on the starting material and compared with X-ray diffraction data on the fired specimens. Scanning electron microscopy revealed systematic changes in the internal microstructure of the shell fragments. Micrometer-sized intra- and inter-layer pores formed in the shells before the complete decomposition of calcite. The shape, dimension and location of the pores within the shell microstructure were found to be directly related to the firing temperature. The analysis of these microstructural features in archaeometric studies offers a good constraint on the estimation of the firing temperature in shell-bearing pottery.
