Kutani Ware Flower Vase, Silver Leaf Emerald Size: 6.5 x 19 cm Traditional Kutani Ware Techniques: ■ Yuuri Kinsai (Gold Leaf Underglaze) Yuuri Kinsai is a unique technique where gold leaf of varying thicknesses is cut into patterns, and then a highly transparent glaze is applied and fired. Unlike Kinrande, which uses gold paint applied with a brush, this technique involves arranging gold leaf to create the designs and patterns. The silver leaf does not peel off and does not rust.
