Moreover, the same thickness of porcelain, the permeability of Bone China is far higher than the same kind of porcelain.3, voice: two grade bone china products gently collided, like sweet voice like the sound of wind chimes, and there will be a few seconds of echo, and other kinds of no, also does not have the characteristics of kaolin porcelain.
