Hamada-gama (Hamada kiln), Mashiko-yaki (Mashiko ware)
Salt glazing, a technique originating in Germany around the 13th century, involves introducing a large amount of salt into the kiln at its highest temperature. The vaporized salt in the high-temperature kiln transforms into soda, reacting with the silica content in the clay, resulting in a glassy surface that adheres to the vessel's surface, providing a glassy appearance with a yuzu skin texture. Before placing it in the kiln, cobalt slip (cobalt pigment) and iron slip (iron pigment) are applied with a brush.
Areas painted with cobalt slip exhibit a deep indigo color, while those with iron slip display a burnt brown shade. Carved “shinogi” patterns create variations in color due to the salt glaze. The expression in the body part may resemble petals or leaves, and the contrast with the yuzu skin on the inside makes it a tea bowl with a rich expression. Perfect for use in the tea ceremony.
