Ultramarine is a blue pigment made from azurite, and has been used in art and religion since ancient times as an extremely rare and expensive material. Even today, it is overwhelmingly more expensive than artificial pigments, and is a color material that symbolizes spirituality and historical value. 〇 Ultramarine (gunjo) 16.58g Made from azurite, it exhibits a beautiful indigo color and has been used as a pigment (rock ultramarine) since ancient times. "Because ultramarine was a very precious and expensive item, until the advent of paint stores, it was considered a 'national treasure,' and required mining and handling permits from the powerful figures of the time, such as Oda Nobunaga and Toyotomi Hideyoshi. By allowing painters to manufacture and use the paint, the gorgeous culture of Azuchi-Momoyama flourished, and the Kaga Maeda clan, among others, also used ultramarine walls in architecture to demonstrate their financial power." (From Yukari Maeda's blog) ● Features of the product on sale: It is a preserved item from the Showa period, and the pigment in test tubes at the time was distributed for educational and art research purposes, but the number of existing ones is small. The seller is Kyoto Ebisuyagazai, and the product name is written on the sticker. ● Condition It is protected from moisture and deterioration because it is in a test tube. "It is in the original container." ● Ebisuyagazai price label (see photo) 4300 yen was the price at the time. It is believed to have been purchased shortly after the war, probably a product from the early Showa period, and it was a price range that was outstanding even then. ● Authenticity of this product: Double red line frame on a white background → It has a simple but strong identification as the above Ebisuyagazai product, and can be distinguished from the labels of other art supply stores (Hokodo and Kissho, etc.). (See photo) ● Price: Even considering the price of goods, it is several tens of times the price at the time. It is a genuine "ultramarine" left by a deceased Japanese painter. ● The amount of 8.9g is suitable not only for actual painting production, but also for exhibition and research. It is positioned as "an amount that can be used, but is more suitable for preservation and appreciation." Artistic value: Adding the added value of "original test tube from the Showa period" further increases its value as an art collection or educational material. That is all for the photos and explanations. We look forward to your purchase after careful consideration.
