Oak Grain and Mixed Woods
- Part of the difference between modern wood and older
wood is that, often, modern wood grows faster becasue
it's not deep in a forest somewhere competeing for
every bit of nutient it can find, but rather it's
farmed along side a bunch of trees of a similar age.
Also, there is research that points towards trees
growing faster as CO2 concentrations increase, so, at
the end of the first period, it's Gaea Hypothosis 1,
Structural Strength 0.
There are a number of cases of wooden object in which
mixed species were used, aparently with an eye towards
wood properties. Elm being split resistant, white oak
being rot resistant, spruce being low desnity, etc....
The one near period example I can come up with right
now (sorry, there's too much blood in my caffine
sream) is a brace with a knob turned from walnut and a
body made of elm.
