10/5/2023 0 Comments Patina color roof panelsI will usually strip the original patina with Muriatic Acid or Soda blast it off. I use Birchwood Casey M-24 liquid solution. Hi, on a number of occasions I have had to turn large copper sculpture black and varying shades of brown as well. I also see green copper roofs where rubbing tree branches or a constant drip from the floor above generate brown areas.Ī. but if you find an old penny in the slats of a boardwalk where nothing has been rubbing it, it will be green. For example, you never see green pennies in circulation, only brown ones. One thing to recognize about the difference between the green and brown patinas is that the green is less abrasion resistant and durable. It is usually better to buy a commercial patinating solution that sort of 'paints' on and which already contains the necessary copper and reaction ingredients to offer the finish you want. The problem is that there are different copper grades, brass grades, manufacturing methods, heat treatment histories, etc., and it is difficult to predict exactly how the copper and other metal components will react with the vinegar & salt to produce various copper salts like copper acetate. We other readers don't know your artistic ability and craft experience but kitchen ingredients are probably either for highly experienced artists or for very general work - not for meticulous work and carefully examined articles like lamps. How do I find the answer to your question.which is my question too.except I want to give a patina to an outdoor copper fountain.which is shiny and really needs "aging'.thanks. I've heard local guys talk about these natural solutions, but do not want to ruin the expensive lamps or get a black finish. Will a weak vinegar -water solution (or salt water solution?) sprayed on the lamps do the trick? How about vinegar AND salt in water. I'm from the East Coast and love the blue-green copper roof colors in Boston and Providence and would like to emulate them. I want to remove the fingerprints, then speed up a "green" patina finish, not the dull copper brown we get here in AZ. A couple of the lamps have fingerprints from whoever packed them visible as a brown/charcoal color. We are in Phoenix Arizona, and just installed some beautiful copper landscape lighting.

In closing, you can achieve your desired color of copper roof patina, but it is not as long lasting as the natural patinas ar e. It will depend on the geographic characteristics as discussed above if you wish to maintain that chemically chosen patina. The copper roof starts out salmon pink brown and makes it’s way to the statue of liberty bright green.Īs I said before, you can alter the coppers color via chemical treatment but here’s the catch, unlike the natural progression of the color from salmon pink to bright green, when you do a chemical treatment to change the patina over the course of a few months, the processes will need to be repeated a certain amount of time later. There is, however, a major caveat to that unnatural choice.Ĭoppers natural patina occurs as a gradual progression depending on the coppers physical orientation and the local weather and pollution levels on a grading scale of lighter and lighter greens. It’s even possible to choose the color of a coppers patina through chemical treatment. That being said it is still possible to use chemical treatments to advance this copper roof patina process. The environment will affect the color and the rate at which the copper changes colors. The thing about copper that a lot of people love is that its natural coloring is very sensitive to the air and certain elements of the air that are geographically relevant, as well as that areas humidity. To properly understand what’s involved in achieving a copper roof patina one must first understand copper.Ĭopper is an extremely durable and versatile metal that can last close to one hundred years and even after can be recycled and almost one hundred percent reused.
