Abstract

ABSTRACT Conservation interventions on silver tarnish and corrosion layers include mechanical, chemical, and electrolytic techniques. Electrolytic reduction is still disputed among metal conservators. The prevailing conviction with many is that mechanical cleaning methods are more likely to maintain control over the result than electrochemical methods. A survey on this subject undertaken in Germany and Austria suggested that this may be due to the traditional approaches of academic education. An electrolytic pencil was further developed and has been applied on naturally aged silver artefacts of the nineteenth and twentieth centuries. The influence of the electrochemical potential difference between artefact and counter electrode as well as of the tip diaphragm material was evaluated. A minimized material loss and a good controllability of conservation interventions on silver alloys were demonstrated.

自然老化银合金工艺品的选择性电化学处理

摘要对银失去光泽和腐蚀层的保护措施包括机械、化学和电解技术。电解还原在金属保护器中仍然存在争议。许多人普遍认为，机械清洁方法比电化学方法更有可能保持对结果的控制。在德国和奥地利进行的一项关于这一主题的调查表明，这可能是由于传统的学术教育方法造成的。电解铅笔得到了进一步的发展，并已应用于十九世纪和二十世纪的自然老化银制品。评估了伪像和反电极之间的电化学电势差以及尖端隔膜材料的影响。证明了对银合金的材料损失最小化和保护干预的良好可控性。

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.
