The study deals with the chemical composition of samples related to the production of a blue pigment/smalt. The samples examined come from the regions of Soví huť and Horní Blatná (north‐west Bohemia) dating to the 16th and 17th centuries. These locations are often mentioned in relation to the discoverer of smalt production technology: Christopher Schürer. The aim of the study is to evaluate the chemical composition of samples from both localities as well as with respect to the ores occurring in the given regions. The samples can be divided into two basic groups. The first clearly represents smalt (potassium glass coloured with cobalt), while the second apparently constitutes the samples of the so‐called ‘speiss’ (an aluminosilicate mass with metallic compounds). The analysis of the smalt confirmed the representation of minor elements bismuth and nickel (always) and uranium and molybdenum (rarely), which are found in Co ores from the Ore Mountains. The paper is the first to present the composition of actual blue pigment finds originating directly from the production sites, while the available literature has so far only reported the results of analyses of the pigments already used when referring to the Ore Mountains.

矿石山区的小规模生产：与波希米亚蓝色颜料生产相关的样品的表征

该研究涉及与蓝色颜料/ smalt生产相关的样品的化学成分。检查的样品来自16和17世纪Sovíhuť和HorníBlatná（西北波西米亚）地区。人们经常提到这些地点，这些地点与smalt生产技术的发现者ChristopherSchürer有关。这项研究的目的是评估来自两个地区以及给定区域内矿石的化学成分。样本可以分为两个基本组。第一个清楚地代表了smalt（涂有钴的钾玻璃），而第二个明显地构成了所谓的“ speiss ”样品（具有金属化合物的硅铝酸盐块）。对smalt的分析证实了在矿石山的矿石中发现的微量元素铋和镍（总是）以及铀和钼（很少）的代表。该论文是第一个提出直接来自生产现场的实际蓝色颜料成分的报告，而迄今为止，可用文献仅报道了提及矿石山时已经使用的颜料的分析结果。
