Pursuit to create a unique blue
Similar to “Original Shu-akae”, “Chizan blue” also focused on color and has a very alluring clear blue color.
However, “It’s very difficult to fire the pottery with blue glaze.” Said Ando. Turkish blue glaze is easy to flow down and crack during the firing process, but when the pottery has cooled, the beautiful cracked pattern called, “Kan-Nyuu” is formed on the glaze surface which made an attractive texture. By carefully examining the color while in the firing process, they were able to create a color which emphasizes the smooth features of Turkish blue glaze even more and succeeded to create a unique blue.
Furthermore, the brand-new color called “Galaxy blue” was a challenge to find a deep blue instead of a clear and smooth blue like “Chizan blue”. “If the pottery is fired too much, the thick glazed part becomes vitrified. To prevent vitrification, we moved the pottery many times in the kiln during the firing process.” Lightly firing the original blue glazed pottery, which has deeper color than Turkish blue glaze, the shiny metallic light resembling stars in the galaxy come out from the matte texture because of the cobalt melted from the glaze. The unique blue colors which Ando creates can decorate the table brightly and received great reputation.
