Abstract


The present study was employed A High Performance Liquid Chromatographic method coupled to a Diode-Array-Detector (HPLC-DAD) to identify the dyestuff in dyed wool samples collected from a rare tunic from the Coptic Museum in Cairo. Results indicated that mixtures of organic dyes were used in dying these samples to produce different colours and the most dominant dyes in the samples were madder and indigo. Based on this investigation, it was concluded that the tested dyed samples belong to the 6-7th century which is in agreement with initial dating of samples according to the style of the decoration.
