Mudejar ceramics in the surroundings of the Castilian Plateau: findings in Bonilla de la Sierra (Avila)

The excavations carried out in the wall of Bonilla de la Sierra (Avila, Spain) have brought to light a set of ceramics from the 14th/15th centuries, Mudejar ceramics (earthenware decorated in manganese green, cobalt blue and gold) and others of local production. Their study by mineralogical methods (X-ray Diffraction -XRD- and optical microscopy) and chemical (Inductively Coupled Plasma Mass Spectrometry -ICP / MS-) comparing them with local ceramics, links them with some fragments of pottery located in the area, not yet identified, and allows establishing a correspondence with other groups that have appeared in nearby towns, located on the Castilian Plateau. The set of decorated earthenware is not uniform. Their Pb/Sn ratios fluctuate over wide margins and make it possible to distinguish autochthonous ceramics, along with others brought from regions with a Mudejar tradition such as the Levantine.
