El ajuar de la necrópolis de Palhais (Beja, Portugal). Nuevos conocimientos sobre la evolución metalúrgica bajo la influencia orientalizante en el extremo suroriental de Iberia

摘要: Grave goods from the Early Iron Age necropolis of Palhais offers a unique opportunity to study metallurgy introduced in Southern Portugal by Orientalizing influence. Metals include two sets instruments for body grooming, an “Alcores fibula” and belt-lock, whose typology and/or decoration shows inspiration. The composition manufacture artefacts is determined conventional EDXRF, Micro-EDXRF, SEM-EDS, optical microscopy Vickers microhardness testing. Elemental compositions indicate low tin bronzes (4.4 ± 2.4%) evidencing significant use scrap as inexpensive raw-material or intentional alloying with amounts economical technological reasons. Post-casting work involved hammering annealing operations showing that these grave were produced functional artefacts. A comparison Late Bronze contents are common among Phoenician bronzes. Moreover, assessment coeval metals Southwestern Iberian Peninsula identifies other features metallurgy, such increase unalloyed coppers leaded bronzes, which can be related diversification bronze production methods during this period.
