In the early Showa era, Ebisuya sealed natural mineral pigments in test tubes, affixed labels, and sold them. The labels, featuring a double red frame on a white background, are crucial for authenticating "Ebisuya" products. The mineral pigment in this listing was acquired from a Japanese painter who passed away 20 years ago at the age of 100. ◎ Scarlet (Hi) No. 15, 16.11g This is a reddish-brown mineral pigment primarily made from natural iron oxide (hematite). It has a calm, deep color tone compared to vermilion or cinnabar, and is one of the traditional red pigments. It is darker than vermilion, slightly brighter than the deep reddish-brown "Bengara" (iron oxide red), and more subdued than "Cinnabar." The coarser the pigment particles, the darker the color; the finer, the lighter. Features: Used in landscape paintings and genre paintings for the reddish-brown depiction of clothing, rocks, buildings, and backgrounds. "Scarlet" is a color of high status, traditionally used in samurai attire and Shinto religious implements. * Preserved in the original test tube, which is unusually almost full. The cork and Ebisuya label are in remarkably good condition, showing little sign of aging. Especially, natural mineral pigments in test tubes from that era have antique value and are sometimes traded at high prices as research materials or collector's items.
