Provenance studies of archaeological ceramics by analysis of their elemental composition are based on the assumption that clays can be distinguished, which were used for pottery manufacture in different workshops or production centres. The clay pastes used for the ceramic manufacture were prepared from natural raw materials extracted commonly in the vicinity of the production sites. Due to different geological contexts of local raw material sources, differences of their elemental compositions can be expected, which are propagated to elemental compositions of the ceramics. The general distinctiveness of natural raw material sources is presumed in the ‘Provenience Postulate’, which, though, has to be verified in each case study. For investigation of ceramics and raw materials potentially used for their manufacture, different practices of clay paste preparation have to be considered which might confine the direct comparison. In the present paper, the study of raw materials will be introduced as integral part of ceramic provenance studies. Issues, such as intra-source and intersource variation, elemental composition in context with clay type and accessory mineral, clay paste preparation, and methodological constraints will be discussed by means of raw material and ceramic data from Greece and the Greek islands.

陶瓷原料：如何识别它们以及如何定位供应盆：化学

通过分析其成分组成对考古陶瓷的起源进行研究的前提是，可以区分粘土，这些粘土用于不同车间或生产中心的陶器生产。用于陶瓷制造的粘土糊是由通常在生产场所附近提取的天然原料制得的。由于当地原材料来源的地质情况不同，可以预见其元素组成的差异，这些差异会传播到陶瓷的元素组成中。天然原料来源的一般独特性在“来源假设”中被假定，但是在每个案例研究中都必须进行验证。为了研究可能用于制造的陶瓷和原材料，必须考虑粘土糊制备的不同实践，这可能会限制直接比较。在本文中，将对原材料的研究作为陶瓷起源研究的组成部分进行介绍。将通过来自希腊和希腊群岛的原材料和陶瓷数据来讨论问题，例如源内和源间变异，与粘土类型和辅助矿物相关的元素组成，粘土糊制备以及方法学约束等问题。
