A close up of the fracturing. Slowly but surely the teapots acquiring a spiderweb like appearance.
By examining the teapots foot or in this case feet, we can see what type of clay was used in it,s construction. In this case the clay used was the traditional dark clay.
The pics above are on the left side a celadon teacup, on the right side a "mi zi"rice glazed teacup. Both cups being made with the dark clay. The metallic like sheen on the rim of the cups in the pics below are caused by being re-fired with an ash glaze. The mi zi teacup seems to crack differently than the traditional celadon, a lot of the cracks run in straight lines which makes it look like the cracks were cut into the glaze, almost like incisions. Both of these cups are very heavy, they do a good job of keeping your tea hot but I have to admit that I only use these for oolong or puerh tea. Drinking green tea from them just doesn't feel right.
