Can carbon 14 identify the age of porcelain?
Identification of porcelain by carbon 14 is not very accurate.The so-called carbon fourteen assay, radiocarbon dating, uses the carbon fourteen, which is widely found in nature, to measure the age of animals and plants. In prehistoric and ancient, the smaller the impact of human activities on the earth's environment, and carbon in nature fourteen proportions remain constant, animals and plants in the survival time, due to its in vivo The new supersedes the old. sake, carbon fourteen also remained constant; however, the once dead, in fourteen carbon will continue to decay, the half-life is 5730 years, in the sealed state and the outside world is obviously different, which is the principle of carbon fourteen dating. We must note that animals and plants belong to the organic matter. However, most cultural relics, such as porcelain, pottery and bronze, are inorganic. Therefore, the application of carbon fourteen dating in archaeology is very limited.
You can use the theory, but the carbon fourteen method is mainly used to identification of ancient cultural relics, generally refers to the more distant, for modern artifacts, fourteen of the carbon method is difficult to get the exact time, China mainly appeared in the past one thousand years, generally not to use carbon fourteen dating method.
