... It can be due to the fact that tileworks might have been manufactured in a region and have been exported to other regions in order to be applied in architectural facades (Mason, 2003). To determine the origin of unknown products, a numerous provenance studies derived from quantitative elemental analysis, such as Neutron Activation Analysis (NAA) (Buko, 1984;Neff et al., 1988;Cogswell et al., 1996Cogswell et al., , 1998Mainfort et al., 1997;Arnold et al., 1999Arnold et al., , 2000García-Heras et al., 2001;Neff, 2002;Glascock et al., 2004;Ben-Shlomo, 2008;Descantes et al., 2008;Iñañez et al., 2008;Partha Sarathi et al., 2008), Particle-Induced X-ray Emission (PIXE) (Zucchiatti et al., 1998(Zucchiatti et al., , 2003Ruvalcaba-Sil et al., 1999;Robertson et al., 2002), and various techniques of atomic spectroscopy and spectrometry (ICP-MS, LA-ICP-MS, ICP-AES, etc.) (Mallory-Greenough et al., 1998;Kennett et al., 2002;Robertson et al., 2002;Neff, 2003;Zucchiatti et al., 2003;Klein et al., 2004;Li et al., 2005;Tiequan et al., 2010) have been carried out on ceramic bodies. These studies have always been accompanied by statistical methods of data handling to attribute one type of ceramic product to a specific zone. ...
