Due to the artistic and cultural value of silk relics,historians and archaeologists have been searching for various ways to accurately determine the origin of silk relic.Using stable isotope techniques in tracing the provenance of ancient textiles has received increasing attention recently,because only small amount of samples are needed.However,the researches related to the origin of silk are mainly based on theoretical analysis,and there is little reports on specific description of experimental methods and objective analysis.Stable isotope techniques was used to trace the origin of modern silk samples,thus it would provide some scientific evidence for the development of ancient Chinese silk.The isotope values of cocoon with regional representation were analyzed,and isotope techniques were used to research the origin of silk fabric.The results show that theδ2H andδ18O of cocoon have a significant linear relationship,and the stable isotope value of cocoon with different types have significant differences.Clustering analysis show that it is difficult to distinguish cocoons with the same type based on the light stable isotopes,while values of87Sr/86Sr have obvious geographical differences.Therefore,it is an effective method to combine the light stable isotopes and 87Sr/86Sr,which used to trace the origin of silk fabrics.The effect of madder on the stable isotopes of silk fabrics we are studied.The results show thatδ2H andδ18O are increased in dyed silk fabrics.The 87Sr/86Sr values of dyed silk fabrics are changed and effected by corresponding madders.The strontium abundances of dyed silk fabrics are all higher than that of control sample.It indicates that dyeing of silk fabrics by madder shows obvious effects on the isotopes.Certain isotopes like O,H and Sr could be chosen in tracing the provenance of ancient textiles after removing the factors affecting the original values according to the changing tendency.Stable isotope testing was conducted on cocoons and silk fabrics after heat aging and light wet aging treatment.The results show that heat aging and light wet aging have different effects on the ratios of stable isotopes in cocoons and silk fabrics.Aging method with water involvement shows greater influence on the ratios of the stable isotopes,especially to the cocoons.But further work need to be done to figure out the change rules.Analysis of the relevant samples in Sichuan and Zhejiang showes that the trend of hydrogen isotope values of samples was:groundwater>raw silk>cocoon>mulberry leaves.The trend of oxygen isotope values was:raw silk>cocoon>mulberry leaf>groundwater.It is indicated that2H and 18O are gradually enriched from mulberry leaf to raw silk process.The carbon isotope values in raw silk were lower than that of the corresponding cocoon samples,which demonstate that 13C was slightly depleted during reeling.In addition,for clusters with stable isotopes,the results of system samples are more reliable than that of the single sample(groundwater,mulberry leaf,cocoon and raw silk).
