Using the comb-pattern texture that the author has been studying, the work is a formative expression of the effect of yin and yang and the aesthetic harmony of sculpture and achromatic color by white and black color contrast, gradually expanding force, and the whirlwind effect of the dragon tree. Also, you can see that the glaze was formed by burning for five to six days in a firewood kiln, which was not glazed, and the natural flame of fire clung to the object. The nature of the work, which was created by the author, adds to the enjoyment of the work, thanks to the thickness of the glaze, or the variety of color changes revealed by the word "Lights and shade."
