Porcelain originated in China (hence where we get the commonly used term “China” or “Fine China” used sometimes as an alternative to “Porcelain” in English speaking countries) however the exact period of discovery is under debate. Porcelain; whether hard or soft falls under the category of “Ceramics” along with Earthenware and Pottery to name a few. The prevailing difference between the two is found in the “firing” temperature required to heat and set the materials.
