In this study,the volatile alcohols and non-volatile red pigments in seven kinds of ink seals were detected by Gas chromatography and High-performance liquid chromatography.The aging curve and natural aging curve were drawn under two artificial aging methods,heating aging and light aging,by using the ratio of the two contents as an index,and the volatility of the alcohols in the seal color traces was summarized.This study provides a feasible method for the physical and chemical identification of the formation time of color mark of seal.
