This paper presents an archaeometric analysis of utilitarian ceramics from a Late Antique rural site in the area of Vallès (Catalonia, Spain), with the aim of investigating their provenance and shedding light on some aspects of their production technology. A total of 55 samples of cooking and common wares were analyzed using a combination of instrumental analytical techniques, including thin-section optical microscopy, X-ray diffraction, and WD-X-ray fluorescence, in order to carry out a petrographic, mineralogical, and chemical characterization of the materials. A variety of petrographic fabrics were identified, generally composed of inclusions derived from granitic rocks, along with metamorphic inclusions in many cases. This variability is not related either to ceramic typologies or to chronological phases but to slight variations in the raw materials and/or paste recipes. Compositional similarities point to a broadly common origin for a large part of the ceramic assemblage. All fabrics identified may be compatible with the hypothesis of a local provenance, although a wider regional provenance cannot be excluded on geological grounds. This study is a step forward into the understanding of cooking and common ware production in northeastern Iberia during Late Antiquity.

普拉萨·马斯特·德·卡斯特拉尔·德尔·瓦莱斯广场（西班牙加泰罗尼亚）晚期仿古乡村遗址的烹饪和普通商品：考古学表征

本文介绍了来自Vallès（西班牙加泰罗尼亚）地区一个晚期古董乡村遗址的实用陶瓷的考古学分析，目的是调查其出处，并就其生产技术的某些方面进行阐述。为了结合岩相学，矿物学，材料的化学表征。鉴定出多种岩相织物，通常由花岗岩岩石包裹体组成，在许多情况下还包括变质包裹体。这种可变性与陶瓷类型或时间顺序无关，而与原料和/或糊剂配方的细微变化无关。组成相似之处指出了大部分陶瓷组件的广泛共同来源。所确定的所有织物都可能与当地来源的假设相符，尽管不能从地质原因上排除更广泛的地区来源。这项研究是对古代晚期伊比利亚东北部烹饪和普通商品生产的了解的又一步。
