Just sitting here listening to Atlas Shrugged (“Money is the source of all good” and “Taggart/Reardon 2010” and “Who is John Galt?”) and enjoying another ‘Delta’ breeze summer evening in Orangevale (Sacramento). Sorry I haven’t updated this series in awhile. I’ve been cooped up in a small classroom for two weeks with twenty other souls, all of whom had hundreds of places they’d rather be, learning the most mind numbing material. I missed my shop.
Two Saturday’s ago I applied the patina. I was initially very disapointed in it and, in fact, really hated it. But just like the weather, all you have to do is wait a bit and it will change. The great thing about these patina’s is they will continue to develop, especially if exposed to sunshine. When I first applied the patina it had some real sick looking yellows and the colors just didn’t look very good. After a week in the sun however, it turned out pretty good I think.
I start the process by laying everything out, sanding both sides with 220 grit, and wash both sides with warm water and dishsoap before rinsing them off and drying. Even though I only apply chemicals to one side the other is glued to a panel so I need it to have some tooth and be free of oils.
I then try to heat the entire surface before working on a particular area. I found it is important to keep the torch moving and avoid burning or overheating one area. The idea is to get the metal to around 200 degrees, about the temperature that causes sprayed water to steam on contact. I then sprayed on various chemicals and flamed them after a moment or two. You can see the colors emerge instantaneously.
I ran into a problem when the bottle with the lighter green solution had clogged up. I poured some of it into a container and applied it with a sponge the way David Marks did. You don’t get as good a spread, but you can better control different textures.
You can see how the chemical steams up on contact. A very good reason to make sure you have plenty of protection. You can also tell from the picture the I am upwind so the spray is blowing away from me.
These pictures do not show the patina very well, but the next bog will!
