It takes about 20 years for Copper to turn greeen in normal conditons. Here are a few ways to make Copper Turn Green Quickly. #1. In the summertime, spray it with a spritz bottle with a mixture of salt, vinegar and water every morning and night. Green in about 2 weeks. When you get the green you like, rinse it with a hot water spray twice a day for a week. Then polish it with felt or canvas and wax it. #2. To turn copper green spray with 1/2 strength Muriatic Acid . Sprinkle with kosher salt. Place in sun. With in 24 hours it will look like 100 years old. #3. Here's a patina formula I found online that will give copper that bluish-green antique look you desire: Take 8 ounces of salt and 8 ounces of ammonium chloride and mix them with a quart of vinegar. Mix in a half ounce of ammonia when you are ready to put it on the copper. Spread it on with a soft brush and let it sit for 24 hours. If you want it darker, repeat the formula and let it sit another 24 hours. When it's done and has sat for a full day, wash it down and protect it with wax or lacquer.

copper will replace silver in silver nitratesolution will precipitate silver and oxidize copper turning to copper nitrate
What happens when a copper vessel is exposed in moist air?
The verdigris that forms on the surface of copper or bronze material exposed to the atmosphere, is generally a copper carbonate. It is not a copper oxide, which is black. Close to the sea, it will also contain basic copper chloride.
What is a better conductor of electricity copper or gold?
Copper is a better conductor of electricity, second only to silver. However, copper will tarnish (oxidize) over time and lose some of its conductivity, while gold will not.
Which metal rusts first copper or iron?
Neither. Only iron rusts. Other metals oxidize.
What are advantages and disadvantages of copper-coated stainless steel water piping?
I cannot imagine any advantage of copper coating stainless? Stainless will not oxidize as readily as copper. I have uses lead coated copper flashing that was exposed to acid rain and bird droppings etc.
What two elements oxidize as they combine?
copper and oxygen
Why is a copper vessel covered with 'green'coating in rainy season?
Copper will oxidize and create that green coating.
Is copper turning green in the air physical change?
The reason that copper turns green is the same reason the metal rusts, oxidization. Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green. Copper is a metal that does not react with water (H2O), but the oxygen of the air will react slowly at room temperature to form a layer of brown-black copper oxide on copper metal which looks like green sometimes...

copper will replace silver in silver nitratesolution will precipitate silver and oxidize copper turning to copper nitrate
Why should peeled potatoes not to be exposed to air longer then necessary?
peeled potatoes should not be exposed to air longer than necessary to avoid oxidation and changing of color of the surface. it contains the polyphenol oxidase which oxidizes catechol to o-diphenol. the phenol oxidases are copper containing proteins which can oxidize phenol derivatives to quinones.
How do you use oxidizing in a sentence?
"After a copper roof is installed, the metal will begin to oxidize and the roof will acquire a greenish patina." "Pure sodium will oxidize rapidly in air, and react explosively with water."
What happens when a copper vessel is exposed in moist air?
