This set has blue, green, and red colors that are reminiscent of the magnificent nebula in space. Special glaze color collides the colors to the extreme within the scope of craftsmanship. Fired at high temperatures, the glaze is smooth and delicate, healthy, and easy to clean. Crafted by kiln change glaze, each color change is slightly different and full of artistic beauty. The dark color system gradually transitions to the internal gradient system, and the color changes are soft and natural.
