Details Calibration of a radiocarbon age of 6550 ± 40 BP of a terrestrial sample from the Northern Hemisphere, using Int Cal04 calibration curve and Ox Cal program version 3.10.
The older a bottle of Chinese vintage liquor is, the higher the price it commands.
Driven by the potential for higher profits, some newly-founded distilleries openly sell liquor whose storage ages are exaggerated.
Details C concentrations are mainly due to variations in the rate of radiocarbon production in the atmosphere, caused by changes in the Earth's magnetic field and variability in solar activity, and changes in the carbon cycle.
The result is that radiocarbon and calendar ages are not identical, and the radiocarbon ages have to be converted to calendar ages using a calibration curve, which describes the atmospheric C concentration in the past measured in precisely and independently dated materials.
Having left enormous negative environmental and socioeconomic impacts all over the world, it is hard to imagine that any sort of silver lining to these tests could exist.
