And it drools on whatever it sits on, leaving rusty stains.  Peter
Happny showed me some great tall light poles in Portsmouth, NH that
(he said) were made of Corten.  They were un-painted, rusty brown, a
little gritty but not flakey, and there were lots of rust streaks and
stains on the supporting concrete.  Of course, you could include the
gradual staining in the planned design of a piece in some cases.  But
not typically.
