Antique dating with science
Researchers at the Oxford Radiocarbon Accelerator Unit (ORAU) in England have applied their craft to sniff out counterfeit whiskeys, with the help of an unsavory ally: 20th-century nuclear tests.
Dendrochronology, or tree-ring dating, provides absolute dates in two different ways: directly, and by calibrating radiocarbon results.
Direct Dating of Wood Cross-dating determines the age of undated wood by directly matching ring patterns with trees of known age.
"So far there have probably been more fakes among the samples we've tested than real examples of old whisky," Tom Higham, deputy director of the ORAU, told .
Among those bogus bottles, reportedly: a Macallan supposedly from 1856 that tests showed to have originated post-1950, when aboveground nuclear tests began upping levels of carbon 14 worldwide.c1836 – gold electroplating was introduced and became popular within a few years.
