【摘要】 采用 X-射线衍射谱及 X-荧光光谱对马家窑文化半山、马厂类型 (约 2 74 0 a BC— 2 0 50 aBC)彩陶颜料进行了分析研究 ,第一次明确了黑、红复彩陶器的颜料成分 ,表明黑色颜料以磁铁矿、黑锰矿或锌铁尖晶石为主 ;红色颜料以赤铁矿为主 ,并首次发现锌铁尖晶石 .分析结果还揭示了半山、马厂类型用两种不同色调的颜料调配复合颜料的机理 .更多还原

【Abstract】 The pigments of colored pottery at the age of Banshan and Machang( 2 740 a BC- 2 0 5 0 a BC) excavated from Gansu province were analyzed by using the X- ray fluorescence spectrometry( XRF) and X- ray diffraction( XRD) .It was shown that the red pigment was made from hematite ( Fe2 O3) ,and the black pigments were chiefly made from franklinite ( Zn Fe2 O4) ,magnetite( Fe3O4) and hausmannite( Mn Mn2 O4) .Especially,franklinite has not been found on the surface of ancient colored pottery before.Furthermore,experimental results show that two similar color minerals were used and mixed together to meet the de- mand of polychrom pottery at that time.更多还原
