The Hungarian coronation mantle was probably produced in the 13th century by re-cutting an 11th century chasuble with gold embroidery on it. The technology of the making of the metal threads was investigated in the course of an overall examination prior to conservationrestoration. The ten samples to be examined were taken both from the original piece and from pieces which have been confirmed as later additions as well as from patches which were sewn to it by way of mending. In order to study the morphology of the threads, scanning electron microscope photos were taken while neutron activation analysis was carried out to detect the major and minor elements in the metal itself. The examination of trace elements took place by optical emission spectrometry. On the basis of the morphology of the threads, the following two major groups were distinguished: 1) metal strips produced from a piece of wire by hammering or rolling spun round a silk core; 2) metal strips cut off from metal plates spun round a silk core. Within each group further characteristics were observed reflecting the advancement of the technology. On the basis of the material tests, two groups were distinguished: 1) gold threads; 2) gilded silver threads. Further sub-groups could be established quite naturally within each group according to the quantitative and qualitative analysis. Thus the complementary morphological and analytical tests not only revealed bits of information concerning the techniques of manufacturing but also made it possible to identify and range certain pieces (e.g. patches) with parts whose chronology had already been verified.
