- Abstract
- Along the southern North Sea coast, late second-early third century CE salt production sites are characterised by extensive refuse zones containing large quantities of what has been described as ‘salt slags’. These ‘salt slags’ are in fact amorphous, heavily vitrified waste materials. This is rather surprising since large-scale vitrification has never been associated with the salt production process. In this paper, these materials are for the first time systematically studied macroscopically, mineralogically and geochemically to determine their composition, formation and relation to the salt production process. To achieve these objectives, a selection of samples was analysed using a multiproxy approach combining thin-section petrography, SEM-EDS and XRD analyses. This approach enabled a detailed characterisation of the vitrification process in the waste materials as well as the identification of high temperature mineral transformations formed in specific (archaeological) conditions. Based on the results, it is clear that the amorphous waste materials should be interpreted as vitrified hearth base fragments formed on the bottom of the hearth due to the presence of external fluxes.
