Minegishi Seiko was fascinated by the life-like distortions found in kohiki and hakeme when he first started making ceramics, but when he actually started making them, he began to feel uncomfortable about creating his own distortions.
When he began to have doubts about his own work, he was impressed by celadon porcelain, where the color and skin of the glaze are valued, and from there he has continued to create celadon porcelain works exclusively. Minegishi Seiko stabilized his celadon techniques and completed a series of works such as 米色瓷 a special cracked beige celadon glaze which is exemplified in this sublime this tea bowl.
The ice crack pattern is a pattern of irregular triangles, squares, pentagons, and sometimes hexagons of various sizes, which look like cracks in the ice.
Careful observation of the surface of the pottery reveals numerous cracks in the glaze. In theory, these cracks, called kannyu, are caused by the different degrees of contraction and expansion between the clay and the glaze contributed to the crackle. In general, the glaze shrinks more than the clay, and therefore the glaze tends to shrink more easily than the clay. As a product freshly removed from the kiln cools down, the glaze crackles and makes a ping-ping sound.
Ice cracking, which is made by double cracking, is a technique in which Seikoh Minegishi specializes.
Double cracking occurs when the glaze is applied thickly, causing a large difference in the absorption rate between the glaze and the base material, and the first cracking occurs during the cooling process in the kiln.
The second cracking is made against the thickness of the glaze when the piece is left at room temperature. The twice cracking appear to overlap each other beautifully as a result. This makes the piece a different work of art from the one that has been pierced once.
Minegishi Seiko has created many works such as jars, tea bowls, and incense burners with ice cracks and has captivated many people with their beauty.
