The natural mineral pigments "Hakuroku" and "Sangomatsu" in test tubes, released by Ebisya in the early Showa era, were rare items that circulated as natural mineral pigments and have a collector's market value completely different from modern synthetic pigments. 〇 Pure Natural - Hakuroku (11.85g) "Hakuroku" is a traditional color name for blue-green mineral pigments, a variation of "Gunryoku" (malachite green). "Hakuroku" is a pale variation of blue-green. It is a whitish-green color with a soft and refreshing tone (see photo). As a natural mineral pigment, it was made by crushing natural minerals until the early Showa era and sold in small portions in test tubes and glass bottles. ◎ Pure Natural - Sangomatsu (Coral Powder) No. 11 & No. 15, 23g This is a mineral pigment made by crushing natural red coral and classifying the particle size. Red coral was harvested in the seas near Japan (especially Tosa, Goto, and Okinawa) and has been used since ancient times for Buddhist altars, ornaments, and dyes. It is more stable than "beni" (red dye) and softer than "shinsa" (cinnabar), making it ideal for expressing women's skin, flowers, clothes, and light, and was also used for pale reds in clothing. Total: 34g 〇 About the Meaning and Value of the Labels ・ The label explicitly states "Pure Natural," likely because the character "岩 (iwa - rock)" was used to represent natural. ・ The price is written on a separate label, and it is believed that the buyer purchased the pre-war Ebisya product after the war, with the price written on it. In the early Showa era, Ebisya sealed natural mineral pigments in test tubes and sold them with labels. The "Ebisya" label with a double red frame on a white background is an important material for authenticating natural mineral pigments from the early Showa era. ・ The natural test tube pigments of that time have antique value and are sometimes traded at high prices as research materials and collector's items.
