清代工笔云龙水波纹绘画颜料及技法研究

利用超景深三维视频显微镜、激光显微共聚焦拉曼光谱仪、能量色散型X射线荧光分析显微镜，对一幅清代工笔画中云龙纹、水波纹所用颜料及技法进行研究。实验结果表明，画作中人物衣服首先以人工合成颜料巴黎绿（Paris green，Cu(CH₃COO)₂·3Cu(AsO₂)₂）整体填色，再用铁红（Hematite，α-Fe₂O₃）描绘出云龙纹、水波纹，绿色、红色颜料共同呈现纹饰内区的暗黄色，此后再以Cu-Zn-Pb合金黄铜粉末勾描出“金边”。此外在画作中还发现了人工合成的群青（Ultramarine，(Na, Ca)_7-8(Al, Si)₁₂(O, S)₂₄SO₄, Cl₂(OH)₂]），结合巴黎绿、群青合成成功的年份，确定了画作完成的时间上限。

Study of Paints and Drawing Techniques of Fine Brushwork Yunlong Ripples Painting in Qing Dynasty

In order to study the paints and techniques of decorative patterns of dragon among clouds and water waves ,the mate-rials based on a Qing Dynasty meticulous painting were measured by three-dimensional video microscopy ,Raman microscopy and energy dispersive X-ray fluorescence spectroscopy .The results showed that the green clothes was firstly colored by Paris green , the decorative patterns of dragon among clouds and water waves were then painted by hematite ,the edge was delineated by brass powder at last .The dark yellow area within the decorative patterns was presented due to the interaction of green and red paints . In addition ,ultramarine blue was checked in the painting .According to the first synthesized time of ultramarine blue and Paris green ,we can make sure the time limit of the painting finished .
