Mudéjar potters brought to Medieval Europe the latest advances in glazing technology, with simple lead or transparent glazes, tin or opaque-white glazes, and finally lustre glazes, which sealed the ceramic and afforded it the beauty desired. Ceramics were produced throughout the peninsula, but the glazed and painted ceramics from the potteries of Paterna and Teruel and the gilded ceramics from Manises were the most keenly sought after and commonly exported.
