More copper etching and patina

Furnished content.

It's me again, I made similar crosses a few months ago with wood borders and patinated copper centers.They sold well and I got a few suggestions on other designs people wanted. These crosses are in response to that request.I made nine total, three wood varieties with three center etchings each. They are about 10-3/4” tall by 7-1/4” wide, 1-3/4” wide arms.The patina was all done with ammonia and salt this time. I really like the blue color producedThe center medallions are done with the same FR4 copper plated circuit board material (black fiberglass). The last jar of the mysterious blue goop from China I used as a resist would never dry. This was motivation to switch to the dry resist film and I am now sold on it!I had to purchase a $10 clothes iron from WallyWorld to laminate the film, but it works fine. If you want to get an idea of what the heck I'm talking about, check out my previous blog on the process or do a search for “dry photoresist how-to”You can see more details into the construction from my previous project.The “IHS” scripts were some of what people asked for, I added more Celtic knots just because….The three wood types were:Maple
Cherryand fumed white oak with Russian olive end capsThe olive end caps are simply because I forgot to cut them from WO and get them into the fumes with the other pieces 8^)These were finished with the spray can version of Minwhack satin polyurethane. This stuff is my favorite poly for small projects. The spray nozzle on these cans is absolutely superb! I get a glass smooth finish. It costs about double over buying by the standard brush on can, but for the convenience it can't be matched.Thanks for looking!
