The Baetican workshops: a starting point to study Terra Sigillata Hispanica

摘要: Terra Sigillata Hispanica (TSH) was a Roman pottery easily recognized by its characteristic intense red color. It produced in several workshops the Iberian Peninsula. Seven of them were placed within Baetica province. Here, we report full characterization series 35 TSH samples from known Baetican centers. Additionally, two recovered Caserio Silverio Mayorga (Antequera, Malaga), possible eighth production center, and another sample with an unpublished stamp (reading ‘NOMO’) are also studied. The main employed techniques stereomicroscopic examination, elemental analysis WDXRF, Rietveld quantitative phase laboratory XRPD, including amorphous quantification innovative G-factor approach and, finally, SEM-EDX for paste-microstructure slip characterization. results rule out as center. stamped is not related to Alameda TSH, it likely La Rioja. Chemical data allows workshop separation when used macroscopic examination. mineralogical show wide range variation content (24–68 wt%), allow firing temperature estimation (900–1000 °C). study highlights markedly thicker slips Andujar productions (20–40 μm), made c. 0.1 μm particles, compared rest (≈10 μm).
