Hispano –Moresque is a name given to two methods; Luster and Majolica, because they came to Spain through the Moorish occupation. The Moors brought two methods of decorating ceramics that when fired look very similar, but the way of working is completely different.
Lustre is bisque, fired clay, covered with an opaque glaze-base that is fired, then decorated with colors made up from precious metals and fired again at between 700º and 800º C. Read more about: On-Glaze
