List of
wood types which can be dated by IR spectroscopy
WOODS WHICH CAN BE DATED
ACCURATELY
(with a margin of error of less than 10%)
|
|
Softwoods: |
fir, pine, Eurasian stone pine and most other
softwoods |
|
Hardwoods: |
linden, poplar, beech, maple and many similar
hardwoods |
|
Oriental woods: |

Asian buddhas |
|

|
WOODS WHICH CAN BE DATED
ACCURATELY
(with a margin of error of between 10 and 20%)
|
|
Softwoods: |
larch |
|
Hardwoods: |
cherry, walnut (*), durmast oak (Quercus petraea),
English oak (Quercus robur) and other locally
growing oaks
(*) for this kind of
wood 3 samples are needed, taken possibly from the
lighter areas of the wood |
|
Oriental woods: |
a
number of woods commonly used for buddhas |
|
African woods: |
a
number of woods used for African sculptures and
masks |
|
WOODS WHICH CAN BE DATED WITH LESS
ACCURACY
|
|
Softwoods: |
cedar |
|
Hardwoods: |
pear wood, willow |
|
Indonesian woods: |
a
number of woods used for sculptures and masks by
Oceanian tribes |
|
WOODS WHICH UP TO NOW HAVE BEEN
DIFFICULT OR IMPOSSIBLE TO DATE
Chestnut, ebony, mahogany,
rosewood, boxwood and a number of Indonesian woods and other
woods for which sufficient comparative data is still
lacking. (For a number of these woods, which are often used
as veneers, dating can be effected on the underlying wood). |
