A team of Dutch and French researchers have released new data pointing to the secret ingredient behind Rembrandt’s use of impasto: the application of thick layers of paint giving his work its characteristic texture and depth.

According to a paper published in the journal Angewandte Chemie, the scientists identified the rare chemical presence of plumbonacrite – a discovery both crucial for scholars researching the Old Master’s paintings, and professionals working on the conservation of his work. Previously, plumbonacrite has only been discovered in a 19th-century work by Vincent Van Gogh, and 20th-century paintings.

The scientists took small samples of paint from three works: The Portrait of Marten Soolmans (1634) held at the Rijksmuseum, Bathsheba (1654) at the Louvre, and Susanna (1636) at the Mauritshuis. Researchers used radiation X-ray technology at the European Synchrotron lab in Grenoble, France, to better understand the chemical composition of the paint used by Rembrandt.

Remarking on the unusual chemical fingerprint of Rembrandt’s paintings, the Rijksmuseum’s Victor Gonzalez said: ‘It is so unusual in Old Masters’ paintings […] What’s more, our research shows its presence is not accidental or due to contamination, but the result of an intended synthesis.’

The presence of plumbonacrite suggests the use of an alkaline binder, used by Rembrandt to prepare paint for his impasto technique. The conservation expert Marine Cotte commented: ‘Based on historical texts, we believe that Rembrandt added lead oxide, or litharge, to the oil in this purpose, turning the mixture into a paste-like paint.’

新闻/2019年1月17日新闻/科学家发现伦勃朗油漆配方的秘密2019年1月17日新的研究揭示了导致里氏病的成分《老主人的画的S》,伦勃朗,马丁·苏尔曼的肖像,1634年。礼貌:wikimedia commons rembrandt,Marten Soolmans的肖像,1634。礼貌:wikimedia commons荷兰和法国的一个研究小组发布了新的数据,指出伦勃朗使用英帕斯托背后的秘密成分:厚厚的油漆层的应用,使他的作品具有独特的纹理和深度。根据发表在《angewandte chemie》杂志上的一篇论文,科学家们发现了铅爆的罕见化学存在——这一发现对研究老主人绘画的学者和从事保护他的作品的专业人员都至关重要。以前,铅爆只是在文森特·梵高19世纪的作品和20世纪的绘画中发现的。科学家们从三件作品中提取了少量的绘画样本:在里克萨斯博物馆(Rijksmuseum)举行的马丁·苏尔曼(Marten Soolmans,1634年)肖像画、卢浮宫(Louvre)的芭丝谢芭(Bathsheba,1654年)肖像画和毛里求斯的苏珊娜(Susanna,1636年)肖像画。研究人员在法国格勒诺布尔的欧洲同步加速器实验室使用了辐射X射线技术,以更好地了解伦勃朗使用的油漆的化学成分。里杰克斯博物馆的维克托·冈萨雷斯(Victor Gonzalez)在评论伦勃朗画作中不寻常的化学指纹时说:“这在老大师的画作中是如此不寻常……而且,我们的研究表明,它的存在不是偶然的,也不是由于污染,而是有意合成的结果。”铅爆的存在表明美国一种碱性粘合剂,伦勃朗用它来为他的英帕斯托技术准备颜料。海洋保护专家Cotte评论道:“根据历史文献,我们认为伦勃朗在石油中加入了氧化铅或氧化铅,从而使混合物变成了糊状的油漆。”国家安全委员会
