Dimpling, scratching, and otherwise defacing metal

Steve, how about rusting them a little with muriatic acid/moisture treatment, and then heating them to orange red hot in the air, they should asquire a black oxide patina. Maybe that will work? The stuff that I heated to that temperature looks kind of rustic after that. use zinc plated ones for this. |

And don't heat zinc plating to red hot (or at least don't breathe the zinc fumes, they aren't good for you). Chris |

I just wanted to point out that the cheap zinc-plated hardware ages REALLY REALLY well when you treat them with muriatic acid, and THEN heat them with a propane torch. |
