“Lusterware: A Middle Eastern luxury item brought to Spain in the late 10th century. Muslim artisans produced iridescent ceramic glazes that appeared as metallic silver, copper, or gold. In the 15th century lusterware tiles and dinnerware were commissioned throughout Europe by princes, cardinals, and popes. Decorative elements included their heraldic emblems along with Moorish signs and symbols.”
