Marker elements of red cosmetics, collected from ancient burials of Matsuyama, Tokushima and Nara Japan, were determined by emission spectrometry (ICP/AES). The mass ratios of Hg, Fe, Cu, and Zn were different between samples. Element levels were compared with reference to relative amounts of sulfur. Of the possible contaminants from the bone and sand of burials, the relative amounts of Hg and Fe to S were most commonly available to evaluate the difference between the cosmetics. The cosmetics were divided into four groups; type I (high Hg with less Fe), type II (both moderate Hg and Fe), type III (moderate Hg with high Fe) and type IV (less Hg with high Fe). The main constituents of cosmetics are mercury sulfide (cinnabar) or ferric oxide mixed with trace metals. Zinc contents differ between the Fe and Hg amounts for the three areas. Cosmetic compositions varied with each burial site, suggesting that they were derived from different mines of ancient Japan.
