THE DETECTION OF METALLIC MORDANTS BY ENERGY DISPERSIVE X-RAY SPECTROMETRY
R.J. Koestler, N. Indictor, & R. Sheryll
SAMPLES WERE TAKEN FROM SEVEN textile fragments. Individual fibers were separated according to color. A single fiber of each color was carbon coated with approximately 15 nm of spectroscopically pure carbon in an Edwards vacuum evaporator and viewed in an Amray 1600T scanning electron microscope with a Kevex EDS spectrometry system. The collection conditions were: 20 kV; 200 seconds; area scanned was full fiber width at about 1–2000 magnifications. The samples were analysed as received, without washing or cleaning. Samples appeared to be clean and unsoiled.
