The typical household and ceremonial ceramic ware of Monte Albán and the Valley of Oaxaca, Mexico, made from a fine gray paste in the middle Pre-Classic period. Grey ware occurs throughout Monte Albán's occupation, with some variations in shape and ornamentation. In the latter periods in the Oaxaca sequence, after the collapse of Monte Albán, Mixtec grey ware was distributed through the Valley. The Zapotecs' merge with the Mixtecs is suggested by the correlation between the distribution of the Mixtec ceramics in Zapotec households, c 1250-1521 AD.
