I have several ideas on this, but I'm sure some other folks have better
ones.

An artist friend of mine asked how to impart a "rust" patina to a welded
steel sculpture. The object in question is made of steel rod/tubing and is
MIG welded together. It is too big to dip in any ordinary container, but
small enough that one man can handle it easily.

I suppose he could wash it in something like laquer thinner and leave it
outside (heavy dew, misty rain, etc. this time of the year). Or maybe spray
it with some mild acid...

Ideas?

Thanks,

Jerry



I'd say hit it with a vinegar douche. No, REALLY!

Wrap it in burlap or similar, wet it down with vinegar and water, and
keep it wet for a day or three, unwrap, and see what it looks like.
Re-wrap/spray, repeat as needed. Or just do the initial treatment to get
things started, and let the atmosphere do the rest.
