This "Autumn Grasses" *Matcha* Tea Bowl is a creation of Kayo from the Ryukoku Kiln in Japan. Crafted from earthenware clay, the bowl features a glaze with a warm, soft luster. Its body is adorned with motifs of autumnal flora; utilizing *iro-e* and gold-painting techniques, the contours of the flowers and leaves are delicately outlined with fine, elegant lines. It stands as a classic example of a seasonal-themed tea bowl within the tradition of the Japanese tea ceremony. The vessel follows the standard form of a *matcha* tea bowl, measuring approximately 12 cm in rim diameter and 7.5 cm in height. The base bears the artist's signature, "Kayo," and the piece comes accompanied by its original wooden box and protective cloth pouch. The Ryukoku Kiln, a renowned studio for tea ceramics within the Japanese Kyō-yaki tradition, was established by the Miyagawa family. The artisan Kayo is a lineage-holding craftsman within the kiln, specializing in the depiction of floral and botanical motifs using gold-painting techniques, executed in a style characterized by its refined elegance.
