Resumo |
Investigations are carried out into the mass gain behaviour of fired clay ceramics following drying (130°C) and reheating (500°C), and the application of these mass gain properties to the dating of archaeological ceramics using a modified rehydroxylation dating (RHX) methodology, a component based approach. Gravimetric analysis is conducted using a temperature and humidity controlled glove box arrangement (featuring a top-loading balance) on eighteen samples of varied known ages and contexts; this occurs following transfer from environmentally controlled chambers where subsamples of these samples are aged at three temperatures (25°C, 35°C, 45°C) following drying and reheating. The sample set consists principally of post-medieval bricks, but also includes some post-medieval pottery as well as both Etruscan and Roman ceramics. A suite of techniques are applied to characterise these ceramics, including XRD, FTIR, p-XRF, thin-section petrography, BET analysis, TG-MS and permeametry. |
