The production of glazed fritware (artificial paste bodied) ceramics i
n medieval Syria is examined in the light of neutron activation analys
is of an excavated sample from the site of Gritille. Reevaluation cast
s doubt on two main commonplaces of Islamic ceramic history: 1) the de
corative technique of lustering, used on some of these fritwares, was
highly restricted; and 2) the production of such luxury ceramics in th
e medieval Islamic world in general was centralized We propose that re
gional ceramic production corresponded to the decentralized system of
government then current in Syria and other geographic and demographic
factors there.
