[Cob] Drying of linseed oil

[jane at kirstinelund.dk]

Some woodworking fellows from northern Sweden I have met claims that
linseed oil made from flax grown in their area dries much faster (and is
generally of better quality) than linseed oil from other places. "Cooking"
(which I have also understood has to do with nasty chemicals rather that
heat) is therefore unnecessary.

I have no idea if this is just local patiotism or if there is actually any
difference. If there is, it could be the sort of flax or it could be the
climate that determines the quality.
