At least one authority, Alan Caiger-Smith, excludes this pottery from the term "Hispano-Moresque", but most who use the term at all use it to include Malaga and other Andalusian wares from the Islamic period as well as the Valencian pottery. When Spanish medieval pottery was first studied in the 19th century, there was awareness of the Valencian centres but very little of the Al-Andalus ones, and there has been a steady re-attribution of types of pottery formerly attributed to Manises to Malaga and the south, which was still continuing in the 1980s, following archaeological discoveries in Malaga, and scientific analysis of the clays used.
