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 .
The pigments and pigments of the Mid-Levels and Machang-type (about 2 74 0 a BC-2 0 50 aBC) of the Majiayao culture were analyzed by X-ray diffraction and X-ray fluorescence spectroscopy. The first black and red The pigment composition of colored pottery shows that the black pigment is dominated by magnetite, black manganese ore or zinc iron spinel, the red pigment is mainly hematite, and the zinc-iron spinel is first discovered.The analysis results also reveal that the mid- Horse factory type with two different colors of pigments formulated complex pigment mechanism.
