ABSTRACT In order to gather information on the technological characteristics of the monochrome decorative wall plasters in some Thracian fresco tombs (4th -3rd centuries BC) found in South Bulgaria, several types of analyses have been carried out. Samples of red, yellow and white large wall-painted fields in different monuments, have been investigated using a combination of Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR) and Differential Scanning Calorimetry (DSC) to identify the organic components of the paint layer. The nature of the pigments has been determined both by X-ray diffraction (XRD) and ATR-FTIR. The obtained results point towards the recognition of final polishing processes performed on still wet plaster. This technique of creating polished wall painted surfaces in combination with organic coatings (known as stucco lustro) is traditionally associated with the Pompean frescoes and the work of roman painters. Based on the technical examination, it can be assumed that in pre-roman time, the Hellenistic paint-craftsmen in Thrace inland were also familiar to this technique. GRAPHICAL ABSTRACT

希腊时期的色雷斯壁画墓中的抛光装饰场-考古学研究

摘要为了收集有关在南保加利亚发现的某些色雷斯人壁画墓（公元前4至3世纪）中单色装饰墙灰泥技术特征的信息，已进行了几种类型的分析。通过使用衰减全反射傅立叶变换红外光谱（ATR-FTIR）和差示扫描量热法（DSC）的组合，对不同纪念碑上的红色，黄色和白色大型壁画场的样本进行了研究，以识别油漆的有机成分。层。颜料的性质已经通过X射线衍射（XRD）和ATR-FTIR确定。获得的结果表明对仍然湿润的灰泥上进行的最终抛光工艺的认可。传统上，这种与有机涂料（称为灰泥灰泥）相结合的方法是创建抛光的墙面涂漆技术，与庞培壁画和罗马画家的作品联系在一起。根据技术检查，可以假设在罗马前时期，色雷斯内陆的希腊化油漆工匠对该技术也很熟悉。图形概要
