Uneven Black Patina...Cure??

by Jack Federico

Thanks for your site,, I've referred here throughout my project (pic attached). The window is 76"x45". I soldered the front, flipped it, soldered the back, fliped it again (7 days later)and touched up the front. When I applied the black patina (after cleaning etc) those areas that I touched up took the patina great, the areas that I left alone look stained grey. My guess is oxidation, 7 days passed before I touched up the front AND I did not steel wool the front panel before appling the patina. My plan is to remove the patina, clean the lines that need attention, steel wool and re-apply the patina... is this correct???.

Answer

Bronze wool would be better to remove the patina then steel wool. It is available at some stained glass shops and I know you can get it at Ace Hardware. They might have to order it for you. Just make sure it s "Fine" grade, not "Coarse" grade.

Then follow the instructions at Patina.

As strange as it sounds, it's important to wax the panel before you patina as well as after. The waxing removes any residual oxidation. You will see the wax I use when you go to the Patina instruction page. Add some white vinegar to the patina. The amount to use is on that page as well.
