Kiln transformation powder lid

I paint white soil on the soil and then bake it in a wood kiln. It is a lid with a characteristic roasted color. The cone is a cute design. Without applying glaze, Since it is baked for 4 days in a wood kiln, The white soil changes to various shades to create a quaint atmosphere. Diameter approx. 6 mm × height approx.6.5 mm Especially because it was baked where the flame hits strongly, The color changes greatly, making it a quaint bowl.
