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. This set of paints was acquired 20 years ago from a Japanese painter who passed away at the age of 100. ◎ Hakugunjo (White Gunjo) 25g This is the name of the mineral pigment, referring to "the finest grade of Gunjo (ultramarine)." The raw material is Gunjo (natural azurite), and its finest grade was called "Hakuban" (white grade). It was used for the pale parts of the sky, highlights on water surfaces, and pale blue patterns on kimonos. There are no pale blue color numbers for decoration. It is now a rare item with high antique value. Especially the natural mineral pigments in test tubes from that time have significant antique value and are sometimes traded at high prices as research materials or collector's items.
