Decorated by a strong and vibrant moulding in dark copper lustre and cobalt blue, with stylised vegetal motifs and the depiction of a castle in the centre.
Lustre is a decorative technique of overglazed painting with metallic oxides which was invented in the area which is today Iraq, sometime during the 9th century, and used to decorate ceramics made throughout the Islamic Middle East. In medieval Spain, lustre potters worked for both Muslim and Christian patrons, and in the 14th century two important production centres emerged in the south-east of the peninsula, one in Islamic Málaga and the second at Manises (near Valencia), which was still Christian.
