Due to its rich history, Umbria has four cities with strong links to the production of ceramics: Deruta, Gualdo Tadino, Gubbio and Orvieto. A source of pride since antiquity for their regional artistic production, the four cities are part of the ‘Associazione Italia Città della Ceramica’. Among the many types of ceramics produced, we will look in particular at maiolica, a technique that consists of immersing a terracotta product in white enamel, decorating it and then firing it a second time.
