“…X-ray powder diffraction (XRPD) is extensively used to characterise ancient pottery in terms of mineralogical composition, and also to constrain the production technology, with particular focus on the raw materials used and the firing conditions, mainly temperature and firing atmosphere (Bimson, 1969;Heimann and Franklin, 1972;Grattan-Bellew and Litvan, 1978;Maggetti, 1982;Martin-Socas et al, 1989;Philpotts and Wilson, 1994;Tite, 1995;Maritan, 2004;Nodari et al, 2004;Papadopoulou et al, 2006;Prudêncio et al, 2006;Prudêncio et al, 2009;Charalambous et al, 2010;Velraj et al, 2010;Mangueira et al, 2011;Maritan et al, 2013). Possible post-depositional alteration processes can also be identified and characterised (Heimann and Maggetti, 1981;Maggetti et al, 1984;Pradell et al, 1996;Buxeda i Garrigós, 1999;Buxeda i Garrigós et al, 2001;Maritan and Mazzoli, 2004;Buxeda i Garrigós et al, 2005;Schwedt et al, 2006;Secco et al, 2011).…”
