handmade
The big mouth of teapot is easy to put into leaves, and direct spout pours water easily. It's half- handmade with zini and uses overall reduction reaction craft. This is the principle of reduction burning. When the temperature in the kiln reaches a certain level, the oxygen in the kiln will be reduced to make it become an oxygen-free burning environment, and the remaining small amount of oxygen will also be consumed by continuous combustion. In this case, the teapot is completely reduced, and the Fe2O3 in the teapot is reduced to Fe3O4, the color of the teapot turns black.
