“…Pb‐bearing glazes, that is, glazes made of Pb compounds (predominantly in the form of Pb oxide) as a flux and occasionally mixed with silica, have been used since the first century BCE (Walton & Tite, 2010). These glazes provide the opportunity to determine the potential provenance of Pb compounds via Pb isotope analysis (e.g., Collerson et al, 2002; Cui et al, 2010; Habicht‐Mauche et al, 2000, 2002; Huntley et al, 2007; Klesner et al, 2021; Marzo et al, 2009; Medeghini et al, 2020; Métreau et al, 2021; Santarelli et al, 2019; Shen et al, 2019; Walton & Tite, 2010; Wolf et al, 2003). Pb has four stable isotopes ( 204 Pb, 206 Pb, 207 Pb, 208 Pb).…”
