Mineralogy and microfossils as key drivers for the characterization of the Phoenician Red Slip Ware from Cádiz (Andalusia, Spain)

•The first analysis of Phoenician Red Slip Ware from Cadiz (Spain) is reported.•XRPD analysis gave information of clays and inclusions of raw materials.•Microfossils micro-analysis was crucial to reconstruct technological aspects.•X-Ray maps showed an Fe-enrichment in the red surface.•Iron framboidal structures and monazite characterize the raw materials used.
