Enhanced C14 Dating
For the objects of the 18th, 19th and early 20th
centuries, radiocarbon dating gives several
ranges of data. CIRAM has developed a
new method limiting the number of those
intervals. It is based on a multiple sampling,
from the center to the outside of the wood,
following the history of the tree. e
opposite Yoruba statue is presumed to date
from the 19th century or earlier.
Using the classical sole sample process,
radiocarbon gave 4 intervals of dates
between 1681 and 1936. Di cult to
e new CIRAM process, by coupling the
xylological study and the statistical treatment
of ve to ten C14 dates, provides an interval
between 1713 and 1740 and a second
between 1907 and 1932. As this object is
known since the end of the 19th century, we
can discard the beginning of the 20th century.
us, the tree was cut between 1713 and
1740. Our new enhanced protocol provides
an accurate dating at 28 years!
