A note on the analysis of metal threads

Contributor(s): Dominique de Reyer | Maria Betbeder | Virginia CostaMaterial type: ArticleArticleDescription: 4 pISBN: 0039 - 3630Subject(s): Copper threads | Electroless coating | Metal theread cross sections | Metallic threads | SEM-EDX | Silver threads | Textile analysis In: Studies in Conservation 3 57 2, 112-115Abstract: The present work demonstrates by means of two practical examples the extreme importance of examination employed in their manufacture. Problems that might be caused by disturbance of surface features during polishing were prevented by covering the sample before embedding with a layer of nickel, using electroless deposition. Results from scanning electron microscopy coupled with energy.dispersive X-ray spectroscopy (SEM-EDX) showed that, although the mean chemical composition of both metal wires is the same, their metallurgical structure is completely different: one consisting of pure silver with inclusions of copper particles and the other silver-copper alloy.
