“…Luminescence dating has also been used, including thermoluminescence (TL) of Minoan kilns and Neolithic settlements in Thessaly and Macedonia (Liritzis, 1979(Liritzis, , 1984Liritzis and Galloway, 1982;Liritzis and Thomas, 1980; and on metallurgical slags from Siphnos and Thasos (Elitzsch et al, 1983). Obsidian hydration dating (OHD) in the Aegean has not been extensively used for dating due to various drawbacks of the method until recently with modern advances (Stevenson et al, 2002;Liritzis, 2006;Liritzis et al, 2004), and the only characterization work that has been done extensively is on obsidian tools to help determine their provenance (Dixon and Renfrew, 1968;Kilikoglou et al, 1996Kilikoglou et al, , 1997Renfrew et al, 1965;Williams-Thorpe et al, 1984;Liritzis, 2008). Part of the issue lies in the large uncertainties with OHD regarding the empirical equation and estimated diffusion coefficient (Anovitz et al, 1999).…”
