This contribution aims to draw up a map of ceramics production sites in the Venetian area from 1600 to 1800, bearing particular attention to institutional and informal devices allowing local production to adapt to European markets trends and innovations. The paper investigates the logics of privileges allowance to private entrepreneurs outside of the guilds framework, conceived probably as a protection for offer more than for demand: they had to do the exploitation of natural resources at a local level (water, raw materials), and of the services labor force accumulating specialized skills working in close contact with foreign invited artisans. The defence and seizure of industrial expertise was in fact the object of enduring court cases between manufacturers fighting to retain and attract highly qualified workers. These were the actual agents' innovation exchange among European, Italian and regional production centres. Continuous exchange and imitation allowed Venetian privileged firms to keep positions in secondary European markets providing most of the demand for local production. The paper is a contribution in a collection edited by Paola Lanaro, submitted and accepted publication by the Center for Renaissance and Reformation Studies of the Toronto University.
