Fragments of wall paintings from Istria, coming from the Basilica of Guran near Vodnjan, from the cemeterial Church of Saint Simeon in Guran and from the Benedictine monastery of Santa Maria Alta near Bale were studied. The analytical instrumental techniques used were Optical Microscopy, Scanning Electron Microscopy equipped with an EDS microanalysis detector, X Ray diffraction, FTIR infrared Spectroscopy and Raman Spectroscopy. Red and yellow pigments used in Guran and Bale have bean derived from red and yellow istrian bauxites, as already demonstrated for works from 11th to 15th century. The blue pigment found in the paintings of the Bale Chapel is a lapislazzuli blue; this fact confirms the literature data referring to the period from 11th to the 16th century. The materials and pigments used at Bale and Guran fit with the Istrian tradition and history of painting going back to the first Carolingian period.
对来自伊斯特拉的壁画碎片进行了研究，这些碎片来自沃迪尼亚附近古兰的巴西利卡、古兰的圣西门墓地教堂以及巴莱附近的圣玛丽亚阿尔塔本笃会修道院。所使用的分析仪器技术包括光学显微镜、配备能谱微分析探测器的扫描电子显微镜、X射线衍射、傅里叶变换红外光谱和拉曼光谱。古兰和巴莱使用的红色和黄色颜料源自伊斯特拉的红色和黄色铝土矿，这一点已在11世纪至15世纪的作品中得到证实。在巴莱教堂的画作中发现的蓝色颜料是天青石蓝；这一事实证实了有关11世纪至16世纪这一时期的文献资料。巴莱和古兰使用的材料和颜料符合可追溯到加洛林王朝初期的伊斯特拉绘画传统和历史。
