Telliing the difference between 10 year old Treated and UnTreated pine?
I've got an outdoor project that I like to use pine I've had in the garage for about 10 years.
Is there a way I can tell?
Some are obvious they are untreated as they are very light.
Some are discoloured from what I believe to age.
But I can't tell the difference.
Any positive constructive suggestions would be greatly appreciated.
thanks in advanceThanks,

Cut a piece and if you get a pungent smell (other than pine smell) from what appears to be clear then its probably treated LOSP, if a greenish tinge then CCA

So pungent ( Not simple pine smell ) is LOSP.
Other is visable greenish tinge then CCA.
Brilliant!
Many thanks.Thanks,

Oh you'll definitely know if it's LOSP treated. Smells a bit like turps and not at all pleasant.
You might also notice it bleeding slightly out of a freshly cut surface.

Over the years over 100 diferent chemicals/combinations have been approved for traetment of timbers - treatments may be against borers (insecticides) and rotting (fungicides) - and most are invisible. A very few are obvious - greenish CCA, smelly LOSP, and black & smelly & carcinagenic creosote.
It is probably safest to assume that your timber is untreated and to treat it yourself. Twenty years ago many shipwrights favoured Epidure, but I am not up to date on the subject.
It might be worth repeating the question on the boatbuilding forum.

Thanks to all.
The gorgeous daughter already has the project inside instead of out.
Will mention to her that it might not be treated.
And to keep it out of the rain if possible.Thanks,
