The Production of Stoneware : A Matter of Taste - In the late Middle Ages, a new ceramic product made its appearance in several regions : stoneware. A minor product at first, it progressively came to constitute the exclusive production of certain workshops. Two conditions are necessary for its fabrication : the choice of the appropriate clay and its firing in a kiln with very high temperature capacity. Each of these conditions implies multiple technological skills. Did the medieval potters succeed in fabricating stoneware fortuitously, or as a result of deliberate research ? Did they benefit from outside technological experience, or models ? And what was the role of the consumer ? For lack of explicit texts, we must seek the answer in the archaeological, and more particularly the Norman, discoveries.
