Superb Shigaraki-yaki Matcha Bowl - Natural Ash Glaze (Bidoro) & Fire Color, Vintage Showa Era This is an exceptional example of Shigaraki-yaki, one of Japan’s "Six Ancient Kilns" with a 1,200-year history. This unglazed tea bowl perfectly captures the essence of Wabi-sabi—the beauty found in the raw, rustic, and natural. A Symphony of Fire and Clay: The visual "scenery" (Keshiki) of this bowl is a result of intense wood-firing in a traditional kiln, where the earth and flames interact to create unpredictable beauty: Hiiro (Scarlet Flash / Fire Color): The vibrant reddish-orange hues on the body are created by the iron-rich clay reacting to the fire. It symbolizes the energy of the kiln. Natural Bidoro Glaze: The beautiful yellowish-green glassy drips on the surface are not artificial. They are "Bidoro" (natural ash glaze), formed when wood ash flies through the kiln and melts onto the clay at temperatures exceeding 1,200°C. Ishihaze (Stone Explosion): Feldspar stones characteristic of Shigaraki clay emerge from the surface, providing a powerful, earthy texture that feels substantial in the hands. Historical Context: The included historical leaflet from a Shigaraki merchant, combined with the vintage telephone format on the document, indicates this piece was crafted during the 1970s–1980s. During this era, Shigaraki was producing some of its finest tea-related ceramics using high-quality local clay. The bowl features a potter's mark (stamp) at the base, signifying it as a handcrafted work from a dedicated studio. Despite its rugged appearance, it is remarkably lightweight at 300g, showcasing the refined skill required to balance aesthetic power with practical use. Dimensions: H 7.5 cm × W 11.5 cm (Foot diameter: 6.0 cm) Weight: 300 g (Ideally balanced for the tea ceremony) Condition: Excellent condition. No cracks, chips, or repairs. Accessories: Original wooden storage box (Tomobako) and historical leaflet.
