This study details the non-destructive chemical analysis of composite silver objects (ewers, situlas, amphora and casket) from one of the most significant late Roman finds, the Seuso Treasure. The Seuso Treasure consists of fourteen large silver vessels that were made in the fourth–early fifth centuries AD and used for dining during festive banquets and for washing and beautification. The measurements were systematically performed along a pre-designed grid at several points using handheld X-ray fluorescence analysis. The results demonstrate that all the objects were made from high-quality silver (above 90 wt% Ag), with the exception of the base of the Geometric Ewer B. Copper was added intentionally to improve the mechanical properties of soft silver. The gold and lead content of the objects shows constant values (less than 1 wt% Au and Pb). The chemical composition as well as the Bi/Pb ratio suggests that the parts of the composite objects were manufactured from different silver ingots. The ewers were constructed in two ways: (i) the base and the body were made separately, or (ii) the ewer was raised from a single silver sheet. The composite objects were assembled using three methods: (i) mechanical attachment; (ii) low-temperature, lead-tin soft solders; or (iii) high-temperature, copper-silver hard solders. Additionally, two types of gilding were revealed by the XRF analysis, one with remnants of mercury, i.e. fire-gilding, and another type without remnants of mercury, presumably diffusion bonding.

这项研究详细介绍了来自罗马最重要的晚期发现之一的苏索宝藏对复合银物体（（，西图拉斯，安菲拉和棺材）进行的非破坏性化学分析。Seuso宝物由十四个大型银色器皿组成，它们是在公元四世纪至五世纪初制造的，用于在节日宴会上用餐，洗涤和美化。使用手持式X射线荧光分析仪沿着预先设计的网格在几个点上系统地执行了测量。结果表明，所有物体均由优质银（Ag含量超过90 wt％）制成，除了几何壶B的碱外。有意添加了铜以改善软银的机械性能。物体中的金和铅含量显示出恒定值（小于1 wt％的Au和Pb）。化学成分以及Bi / Pb比表明，复合物体的零件是由不同的银锭制成的。ew子有两种构造方法：（i）底座和主体分开制造，或者（ii）e子是从单个银板上抬起的。使用以下三种方法组装复合物体：（i）机械固定；（ii）低温铅锡软焊料；或（iii）高温铜银硬焊料。此外，XRF分析还揭示了两种镀金类型，一种具有汞的残留物，即火烫金，另一种不含汞的残留物，推测是扩散键合。（i）底座和主体是分开制造的，或者（ii）檐口是从一张银板上抬起的。使用以下三种方法组装复合物体：（i）机械固定；（ii）低温铅锡软焊料；或（iii）高温铜银硬焊料。此外，XRF分析还揭示了两种镀金类型，一种具有汞的残留物，即火烫金，另一种不含汞的残留物，推测是扩散键合。（i）底座和主体是分开制造的，或者（ii）檐口是从一张银板上抬起的。使用以下三种方法组装复合物体：（i）机械固定；（ii）低温铅锡软焊料；或（iii）高温铜银硬焊料。此外，XRF分析还揭示了两种镀金类型，一种具有汞的残留物，即火烫金，另一种不含汞的残留物，推测是扩散键合。
