A method for the differentiation of natural from synthetic dyes on textiles is discussed, and a simple method for the identification of natural dyes on old textiles is established. Identification is accomplished by the preparation of lakes of the dyes and their color comparison with lakes of known dyes. Thin-layer chromatography for the identification of certain red dyes and yellow dyes is also discussed, and several examples of identification of unknown dyes are described.
