You may see some crackles before or after using our pottery products, this is a normal phenomenon that occurs in pottery products around the world. Why it happens? Due to thermal expansion mismatch between body and glaze. After the glaze solidifies, it shrinks more than the body and to relieve the tension being stretched, it shows these crackles.

Also you may hear some ticking sound before or after using our products. Why it happens? it's just a thermal shock caused by sudden shifts in temperature, as in the firing stage the temperature should be 1000-1100 degree celsius, it'll stop doing this after 2-3 times of using it.
