Scholars who reject the above scenario believe, on the basis of many recent archeological finds, that earthenware and porcelain are quite separate. The two are made from completely different materials--whatever glaze is applied to potter's clay, and however high the temperature at which it is fired, it cannot be made into porcelain, and china clay fired at a low temperature will not make earthenware.
反對前述說法的學者，根據近年大量出土的考古資料，認為陶是陶，瓷是瓷，兩者成份根本不同，陶土無論如何上釉高溫燒製都不可能變瓷，瓷土燒低溫也不會成陶。
