I am restless, eager to move on..
to grow again and to face the sun's fire
And to let all impurities melt away.
Slowly as I pick my way forward I find myself curious..
Do I need to let go or disentangle myself...

LEARNING ABOUT TIMBER AND TREES
RED OAK
Everywhere I look these days I see "Red oak" mentioned. The large number of U.S.Asian blogs and pages I look at and of course "The Woodrights Shop" may go some way to explain this, but I have recently found this timber at the masters warehouse store near Canberra airport.Being me I wondered what it was, where it came from, how useful it is to me and of course is it being produced sustainably?
Here is what I have found out:
Red OakQuercus Rubra Family FAGACEAE
| Red Oak |
Common name(s): red oak, northern red oak
Synonym(s): Quercus borealis F.Michx.
Conservation status: Least Concern (LC) according to IUCN Red List criteria.
Habitat: Valley floors to mid-slopes of hills and mountains Quercus rubra is native to south-eastern Canada and north-central and eastern USA.
Red oak is hard timber from a rapidly growing tree, which naturally make it a good plantation tree. It is straight grained with with large open pores. Apparently the grain is so open that smoke can be blown all the way through a flat-sawn board.
