“…The mineralogical composition of the ceramic body was determined via XRPD and used to reconstruct their original firing temperature ('archaeothermometry', Rice, 2015, pp. 99-116;Quinn and Benzonelli, 2018). This method makes use of the presence/absence of mineral phases that form or disappear at specific temperatures and atmospheric conditions, as determined experimentally and reported in 'bar diagrams' (Maggetti, 1982, p. 128;Maritan, 2004, p. 304;Maritan et al, 2007, p. 533;Nodari et al, 2007, p. 4668) (Figure 3).…”
