“…The criteria used for classification are based on discussions of changing pottery forms and styles for the periods in question (e.g., Hennessy, 1967;Amiran, 1969Amiran, , 1985Callaway, 1972Callaway, , 1980Hanbury-Tenison, 1986;Stager, 1992) A classification system was devised to create both superclasses and subclasses of pottery.
