The master of slip and glaze called “Kohiki, Mishima, Kurotokusa”
“Kohiki, one of Suzuki Touen’s major series is Hidetoshi’s specialty.
Kohiki is pottery coated with white slip on the biscuit and coated with a transparent glaze at the end and fired. To make the biscuit, he uses red clay which contains a lot of iron. The color of the clay underneath the slip give the pottery a warm texture. “Mishima” is a type of pottery which was born in the Korean Peninsula. Before drying the already formed pottery, it is decorated with flower design stamps called “Mishima decoration”. Then it is covered with a white slip as well as Kohiki and the surface is wiped off, so the slip only covers the grooves, so the decorations reveal themselves.
Kurotokusa is the design which has been loved since 1600. It stands out with black and white contrast, drawing vertical lines with water repellent and then coated with black slip. Lining with strength and weakness can express unique texture of hand painting.
The sharpness of the pottery by using deep black slip makes the dish look even better.
“A slurry clay called slip has lots of variety, some of them are colored or give ceramics pinkish color after firing. I choose different slips depending on the pottery.” Says Teppei. Also, he carefully blends the material of slip using hydrometer called baume scale to measure density of liquids because the pottery turns out different depending on its consistency. In addition, there are 4 different types of transparent glaze, he chooses them depending on how he wants to finish the pottery. He carefully adjusts the density of glaze to make the texture to match the pottery.
