Three Transylvanian fragments of some 18th century Saxon tiles obtained from excavations in the Central Railway Station Square in Sibiu (Romania) have been studied by Raman microscopy, FTIR, SEM-EDX and XRF techniques. A lead-rich aluminosilicate was found to have been used as enamel/glaze for the tile fragments. An analysis of the band components of the Raman spectra of the enamel of one fragment in the 400−1200 cm⁻¹ spectral region indicates that their processing temperature was in the 600−800 °C range, in good agreement with the temperature obtained from FTIR spectra of the other two tile fragments.

使用光谱技术确定18世纪Transylvanian炉灶瓦的燃烧温度

通过拉曼显微镜，FTIR，SEM-EDX和XRF技术研究了从锡比乌（罗马尼亚）中央火车站广场的挖掘中获得的约18世纪撒克逊瓷砖的三个Transylvanian碎片。发现富含铅的铝硅酸盐已被用作瓷砖碎片的搪瓷/釉料。对一个碎片在400-1200 cm ^-1光谱区域中的搪瓷拉曼光谱的能带成分进行分析表明，它们的加工温度在600-800°C范围内，与从FTIR获得的温度高度吻合其他两个图块碎片的光谱。
