This paper aims to apprehend evolution of ceramic manufacture strategy in the Johnston-Vieillard manufactory (Bordeaux, France), which produced white earthenwares between 1835 and 1895. Glazes of fragments of 76 sherds, dated from different periods of the 19th century and found in excavations were characterised thanks to combined chemical and mechanical analysis. A comparative study was carried out for the determination of boron content in glazes by LA-ICP-MS and ion-beam analyses (PIGE). In addition, an innovative study of the mechanical characteristics of the glazes by nanoindentation experiments was carried out in order to see whether or not the evolution of the glaze recipes was accompanied by an evolution of their mechanical properties.

Johnston-Vieillard 制造厂（法国，19 世纪）的白色陶器釉的化学和机械特性

本文旨在了解 1835 年至 1895 年间生产白色陶器的 Johnston-Vieillard 制造厂（法国波尔多）的陶瓷制造策略的演变。 76 件陶器碎片的釉面，可追溯至 19 世纪不同时期并在发掘中发现结合化学和机械分析进行了表征。通过 LA-ICP-MS 和离子束分析 (PIGE) 对釉料中硼含量的测定进行了比较研究。此外，通过纳米压痕实验对釉料的机械特性进行了创新性研究，以了解釉料配方的演变是否伴随着其机械性能的演变。
