In the early Showa era, Ebisuya sealed natural mineral pigments in test tubes, affixed labels, and sold them. These labels, featuring a double red frame on a white background, are crucial for authenticating "Ebisuya-released" products. The pigments in this auction were acquired 20 years ago from a Japanese painter who passed away at the age of 100. ◎ Honshu (Vermilion) 20g "Honshu Kiguchi" (vermilion, yellowish) from Ebisuya in the early Showa era refers to a specialized classification of vermilion made from natural cinnabar at the time, specifically those with a "strong yellowish tint." The fact that it is natural cinnabar-based Honshu from the early Showa era makes it extremely rare. It is brighter than Akaguchi (reddish) and produces a color tone close to vermilion. It is a rare item with high antique value today. ◎ Red (Aka) - Cinnabar-based 15g When it was not possible to finely classify lots with subtly different hues, or when selling as a general-purpose red for a wide range of uses, it was sometimes simply labeled "Red." The reasons this product can be considered cinnabar-based are its weight, luster, and depth, making it "Red" from cinnabar. ◎ Sangomatsu (Coral Powder) 5.79g This is mineral pigment made by crushing natural red coral and classifying the particle size. Red coral was harvested in the waters near Japan (especially Tosa, Goto, and Okinawa) and has been used since ancient times for Buddhist implements, ornaments, and dyes. It is more stable than beni (rouge) and softer than cinnabar, making it ideal for expressing the skin of women, flowers, clothing, and light, and was also used for pale reds in clothing. Total: 41g Especially the 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.
