In situ, non-invasive investigations by means of portable X-ray fluorescence and fibre optic reflectance mid-infrared (mid-FTIR) spectroscopy of painted Böttger Stoneware objects have been carried out through the MOLAB transnational access to the Porcelain Collection of the Staatliche Kunstsammlungen in Dresden. It has been possible to gather information regarding the composition of the black glaze by applying a principal component analysis to the elemental analysis to distinguish between the variations of lead, iron and manganese compositions of each glaze. It has been furthermore feasible to combine molecular spectroscopy for characterization of the constituent painting materials, namely lead white as cerusite and hydrocerusite, the use of cinnabar, azurite and Prussian blue leading to a better knowledge of the state of conservation and utility of certain pigments that may give rise to chronology of the decorative artwork. The identification of oxalates namely whedellite and moolooite are assigned as degradation products relative to the decorative areas.
通过MOLAB跨国访问德累斯顿国家艺术收藏馆的瓷器藏品，利用便携式X射线荧光光谱仪和光纤反射中红外（中红外傅里叶变换红外光谱仪）光谱仪对彩绘博特格炻器进行了原位非侵入性研究。通过对元素分析应用主成分分析，区分每种釉料中铅、铁和锰成分的变化，从而有可能收集有关黑色釉料成分的信息。此外，结合分子光谱对构成绘画材料进行表征，即作为白铅矿和羟氯铅矿的铅白、朱砂、蓝铜矿和普鲁士蓝的使用，有助于更好地了解某些可能影响装饰艺术品年代测定的颜料的保存状态和用途。草酸钙矿物即水钙草酸钙和钼钙草酸钙被鉴定为装饰区域的降解产物。
