Web2. Symmetry Analysis Ceramics break, but they don’t decay. Once abandoned and buried in the ground, pottery will survive without much additional damage for hundreds, even thousands, of years. Over the same period many other goods, especially organic artifacts such as those made from cloth, leather or wood will largely vanish without trace. WebPorcelain was first made in China during the Tang dynasty (618–907 ce). The kind most familiar in the West was not manufactured until the Yuan dynasty (1279–1368 ce). It was made from kaolin (white china clay) and petuntse (a feldspathic rock also called china stone), the latter being ground to powder and mixed with the clay. During the firing, which …
