ResumoTextiles from Swedish churches are conserved at the Conservation Department of the Swedish National Heritage Board. Eightynine samples of metal thread from 29 objects dating from between 1619 and 1751 have been examined in order to investigate production methods, preservation and environmental effects with regard to metal threads in ecclesiastical textiles. Examples of possible Milanese gold threads are discussed as well as specimens from Queen Kristina's funeral clothing, but the main focus of this study is on the 14 episcopal copes made for the coronation of King Adolf Fredrik in 1751. The specimens were examined by a variety of methods including visual inspection, stereo magnification and scanning electron microscopy–energy dispersive X-ray analysis (SEM-EDX). The environmental conditions and storage materials were recorded for each object. The metal used for most of the specimens is silver gilt. The objects are in relatively good condition, probably due to good quality and careful handling. The metal shows varying degrees of corrosion. Possible reasons such as air pollution and conservation treatment are discussed. The findings will form the basis of continuing work on a database of metal threads at the National Heritage Board. The plan is for this data to be made available to conservators and others working with similar issues.
