摘要

在15 - 17世纪的油画层中发现了无色的玻璃颗粒。一些历史资料提到使用精细磨碎的玻璃粉作为固体干燥剂。为了评估玻璃颗粒添加到涂料中的干燥效果，本研究侧重于红湖重建，并使用傅里叶变换红外(FTIR)分析跟踪其自然干燥。对三种钠钾锰含量不同的玻璃进行了研究。在每个样品中都观察到干燥速率的显著差异，这表明成分(含或不含锰)与作为干燥剂添加的玻璃颗粒的大小之间存在关系。这种FTIR方法突出了在涂料层中混合的玻璃粉干燥效应中涉及的几个复杂机制。

Colourless Powdered Glass as a Drier for Red Lakes: On the Influence of Composition and Particle Size

Colourless glass particles are found in oil painting layers from the fifteenth-seventeenth centuries. Several historical sources mention the use of finely ground glass powder as a solid drier. In order to assess the siccative effect of glass particles added to paint, this research focused on red lake reconstructions and followed their natural drying using Fourier transform infrared (FTIR) analysis. Three glasses with different sodium-potassium and manganese contents were studied. Significant differences in drying rates were observed in each of the samples, indicating a relationship between both the composition – either enriched with or without manganese – and the size of the glass particles added as siccatives. This FTIR approach highlights several complex mechanisms involved in the drying effect of glass powders mixed in paint layers.

期刊介绍： Studies in Conservation is the premier international peer-reviewed journal for the conservation of historic and artistic works. The intended readership includes the conservation professional in the broadest sense of the term: practising conservators of all types of object, conservation, heritage and museum scientists, collection or conservation managers, teachers and students of conservation, and academic researchers in the subject areas of arts, archaeology, the built heritage, materials history, art technological research and material culture. Studies in Conservation publishes original work on a range of subjects including, but not limited to, examination methods for works of art, new research in the analysis of artistic materials, mechanisms of deterioration, advances in conservation practice, novel methods of treatment, conservation issues in display and storage, preventive conservation, issues of collection care, conservation history and ethics, and the history of materials and technological processes. Scientific content is not necessary, and the editors encourage the submission of practical articles, review papers, position papers on best practice and the philosophy and ethics of collecting and preservation, to help maintain the traditional balance of the journal. Whatever the subject matter, accounts of routine procedures are not accepted, except where these lead to results that are sufficiently novel and/or significant to be of general interest.
