!! Thanks for replying, George, but unfortunately your reply is absolutely & completely incorrect and dangerous. I have seen these on-line with a beautiful, very rustic looking patina of red and black.Ĭan anyone help me to get this look? And how to keep it? Hello! I am in process of building a barnwood cabinet, with a copper sheeting over the top. 5 days makes a beautiful speckled midnight blue and black patina. The longer you leave it, the darker the blue color will be. Make sure it is all well mixed and then bury your copper piece in the mixture. You have to use a lot of salt, about the same amount as the ammonia or even more. Try a buried patina - use either sawdust or non-clumping clay cat litter in a ziplock bag and dampen it with the ammonia, then add the salt. Ammonia and Salt makes a really great blue patina on the copper. A strong solution of Miracle Grow & water, sprayed on copper, will turn it a beautiful green patina overnight. After polishing the copper you need to lacquer or clearcoat it or it will quickly tarnish.Ī. I find Revere copper cleaner a good compromise for most things (much faster than Brasso but still leaves an acceptable copper color). Vinegar + salt is fast as lightning but leaves copper very raw and salmon looking. Generally the warmer the glow that a polish imparts, the slower it works.īrasso is very slow but can't be beat for the final finish. There are countless brass polishes that can do this. Your request is for the opposite of what this thread is about, but is covered by many threads of its own on this site. It's been weathered and I like the look of the copper not the patina look? Any help for me? Thanks. It's a moon with a stained glass cobalt blue along the side of it. I've recently purchased a copper weather vane and would like to know how to clean it to it's original copper then treat it to keep it shiny and new looking. The label on bleach clearly says: "DO NOT MIX WITH OTHER HOUSEHOLD CHEMICALS. !! You do realize Vinegar and Bleach make chlorine gas, and at 1000 ppm can literally kill you? Not to mention the damage it can do to the surrounding area.īe VERY careful doing this. And, I just visited a site where a fellow sprayed on some plant fertilizer, letting it soak in cloth spread out on his copper garden ball, and it turned green. Just realized that the coating may be lacquer, so It is $100 Canadian here, though.) John H Ī. Good luck! (By the way, I saw the fireplace bowl that you spoke of for sale here, and it is tempting. Why not try some things on the bottom in a small area. I don't know if that would work for you, or if a diluted furniture stripper would work. I rubbed it with a solvent-dampened coarse cloth, and it came off. I am not an expert, just learning about this antique patina thing myself, but when working on some copper salt/pepper shakers yesterday, tried Acetone to dissolve the sprayed-on plastic coating that was keeping the top bright. Thanks, Greg Z Ĭontracting/Appraisal - Richardson, TexasĪ. If I am going to try the vinegar and bleach method, How do I go about cleaning the surface of the copper before applying the vinegar and bleach patina? Any help? The copper surface appears oily which I presume slows the aging process. The label on the box says that the copper surface will age to a beautiful patina finish. The copper is bright and shiny almost like a new penny. I have a outdoor fire pit with a 35" copper bowl that I bought new at Target today. Make sure the metal is oil free before applying patina. Steel wool has oil in it to keep it from rusting. Bleach is chlorine gas dissolved in alkali if you neutralize the alkali with acid, the poisonous chlorine gas comes pouring out into the air.Ī. !! Be very careful with that vinegar and bleach thing! One of the most important household safety tips-which you'll read everywhere-is never mix bleach with other household liquids (except laundry detergent which is designed for use with bleach).
