The Statue of Liberty is green thanks to the copper patina effect.Įssentially, the green color results from the copper coming into contact with water, oxygen, and carbon dioxide over time, causing a coating to build on the surface. The Statue of Liberty isn't made out of a green metal its surface is mostly copper - and copper doesn't come out of the mill looking green. So, what is it called when metal changes color? The patina effect - a color change in red metals caused by oxidation. What color is it? If you answered "green, with maybe a little blue," you're correct … but you wouldn’t have been 140 years ago.Ĭopper, bronze, brass, and other metal used in interior design and architecture may not look the same color 5, 10, 20, or even 50 years from now as they do today. Think of the Statue of Liberty for a moment. How The Patina Effect Creates Green Metal What causes green metal? It all begins with a slow-moving special effect. This transformation should be part of your decision marking process when choosing metal mouldings for your next architectural project. Some metals rust while others slowly turn green. Don't be concerned this is normal - and maybe even good! Regardless of whether you prefer shiny or tarnished looks, you need to be aware of the difference between brand-new architectural metal now and one affected by corrosion and oxidation. Is youthful glow better, or is the weather look of experience more desirable?Įach architectural metal has a different response to aging. It is always advisable to test JAX Green Patina in a small inconspicuous area to make sure that it does not adversely affect or damage the surface being treated.įor a more authentic look, first apply a JAX Darkener to the metal before applying the JAX Green Patina.ĭo NOT apply JAX Green Patina to hot metal or roofs ? the chemicals will simply evaporate and have little or no effect.Like with many other things in life, age is a big talking point in decorative metals. Do not mix JAX Products with any other chemicals. Make sure to refer to the Safety Data Sheets for additional information before you begin. When you dispose of used products and containers, please do so in at an approved waste disposal facility. Contaminating the original container will seriously reduce the shelf-life of the product.Īlways use JAX Products in plastic or glass containers.
Always store JAX products at room temperature, in tightly closed original containers AND in a locked, safe place. JAX products never expire, however, they can deteriorate over time if not cared for properly. Once you are happy with your finish, you may wax, oil, or lacquer the metal as a final step, although in many cases leaving the metal ?unprotected? may be desirable. We do NOT recommend applying JAX Green Patina by dipping your metal into JAX Green Patina. Unlike the JAX Blackeners and Darkeners, the JAX Green Patina does NOT work instantaneously. Brush the patina onto the metal until a dull film appears.? The appearance of the film indicates that the patina has adhered to, and is reacting on the metal.? Additional coats may be applied.? Allow each coat to thoroughly air-dry (24 hours) between coats is recommended. Use a stiff bristle brush and apply the JAX Green Patina directly to the metal. To be safe, eye protection is always recommended. Wearing gloves is highly recommended as to not introduce oils from your hands to the metal.
Regardless of what you use to clean your metal, we recommend using Dawn Dishwashing Liquid as the final step before applying the JAX Green Patina. Your choice of cleaner depends on what you are trying to remove from your metal. JAX manufactures metal cleaners that are optimal for prepping your metal, but there is no one cleaner that will guarantee perfection. To ensure the best results, clean your metal of all lacquer, oil, grease and wax.
