Archie Zietman Posted July 22, 2008 Share Posted July 22, 2008 Hello. I was recently at Penland School of Craft, and all of their railings are made by blacksmiths who have taught there. They also all have the same kind of finish. It's slick and waxy looking and is patchy red and black. I really really like it, but when I asked, they just said it was "goop". so how might it have been done? partial russet-finish? some fancy combo of oils? I really want to know because I really like it. Thanks eversomuch! be merry, Archie Quote Link to comment Share on other sites More sharing options...
KevinD Posted July 23, 2008 Share Posted July 23, 2008 Some sort of patina with a wax or clear coat finish. There are all sorts of finishes for metal. Do a Google images search for patina. Quote Link to comment Share on other sites More sharing options...

Archie Zietman Posted July 23, 2008 Author Share Posted July 23, 2008 here's a photo, not mine, but it shows the patina. looking at it again might it have been rusted and then oil finished? On other railing, the red and black were more mixed and patched. Quote Link to comment Share on other sites More sharing options...
ornametalsmith Posted July 23, 2008 Share Posted July 23, 2008 BY JOVE I think you've got it. With maybe a linseed oil, turp, bees wax, (japan dryer possibly) finish. Doesn't look like a painted(faux) finish to me. Quote Link to comment Share on other sites More sharing options...
Archie Zietman Posted July 23, 2008 Author Share Posted July 23, 2008 I'm just wondering how they would keep the rust when heating for the oil finish. Maybe they did the oil finish first, then rusted, then wax/ clearcoated it? The rust finish is smoothed and shinied up too. Quote Link to comment Share on other sites More sharing options...
Dave Leppo Posted July 23, 2008 Share Posted July 23, 2008 The black may be fire scale, which resists rust. Wherever the scale breaks off, or cracks, rust will form. Leave the piece outside for a month, then clear coat with whatever. Here's a tripod plant stand I made, you can see that it's pretty black, with some rust where the ring was forge-welded. I left it out for a few days in steamy central PA, and then linseed oiled it. Quote Link to comment Share on other sites More sharing options...
easilyconfused Posted July 23, 2008 Share Posted July 23, 2008 I have troubles not getting that problem. Seems like everything I make that isn't painted starts to rust under the wax coat and I can't figure out what I'm doing wrong since it only happens on projects made at the home forge..... Problem is that the rust keeps spreading on my stuff..... Not to hijack but anyone know a way to combat it? Quote Link to comment Share on other sites More sharing options...
cwilliams Posted July 26, 2008 Share Posted July 26, 2008 I got a finish not to unlike that one time, what I did was wire brush the piece then spray with a acid in a spray bottle. The acid rapidly rusted the piece, I every 24 hours would hand wire brush the piece then spray more acid on it. After about a week I had a beautifull multi colored rusted piece, at this point I go one of two directions, if the piece is small I put it in boiling water which will turn the orange rust black then clearcoat. or if I want the orange in it I rinse very well with water and let it dry and clearcoat. I use permalac for my clearcoat. Chris Quote Link to comment Share on other sites More sharing options...
