![]() Johnson’s, Boston, Butchers Past Wax or any non-abrasive, natural paste waxes are recommended.įor quick and shiny cleanups, use a spray-after-wash auto detailer that contains only wax. What kind of paste wax is recommended for bronze?ĭo not use automobile paste-waxes, as these will permanently damage bronze. (Note: De-mineralizing agents can be found in most pool supply stores.) Remove the spots using a good paste wax, and use de-mineralizing chemicals to treat the water. This happens often in locations with heavy mineral content. Again, simply clean it up with paste wax, and touch up the color with Kiwi wax.Īfter bringing your bronze home, high calcium levels in the water often cause white spots, especially in fountains. You may also see some white spots due to residual ceramic material from casting. If you see these crystals, simply wash them off, or clean with paste wax. The borax may be still in the metal, but not visible until it gets wet. What about white spots? When you first get your bronze, borax powder – used in casting – can look like crystals. ![]() Simply paste wax your monument every year or coat with matte finish Permalac, urethane, or lacquer spray. How can I keep my bronze the same original color? Today, many foundries actually acid-etch the metal, to give the effect of antique verdigris. Many people find this antique patina of green desirable, and may want to quickly customize their bronze using a tinted finish. Placing your mascot or statue outdoors will naturally cause it to turn green, verd or verdigris (green patina). How can I let my bronze naturally turn verdigris? In direct sun, un-maintained and exposed to the weather, more than of 5-10 years (slightly shorter on the beach with salt water spray). How long does it take for bronze to get verde? Foundries may also add wax, lacquer, or urethane coatings to protect the valued warm bronze color. This protective layer changes the outside metal structure to prevent corrosion. Today’s bronze art objects come from the foundry with a chemical patina (green film). The difference between the two finishes is whether the park has decided to preserve the bronze with wax, or let it go natural (‘verdigris”). Other monuments are rich brownish bronze. Go to historical parks such as Monument Avenue, in Richmond VA, Washington DC, Gettysburg PA, or NYC’s avenues of art, you’ll see that the bronze sculptures, of famous American soldiers, mascots, and even some fountains, are green. ![]() Hence, the Statue of Liberty stays green. Once oxidized, this verdigris crystalline layer (called a “passivization layer”) actually protects, and seals the metal from additional corrosion. The Statue of Liberty is green – due to oxidation. When bronze oxidizes (comes in contact with water and oxygen) or rusts, the process causes the bronze to turn a green color. How to care for bronze if the Statue of Liberty is bronze, why is it green?īronze alloys contain copper. Our zinc and patina coated applications have been through accelerated testing and performed hundreds of hours beyond the "full life" thresholds set by the ASTM standard testing method.Bronze Care About Bronze Patina (coloring) The method that we use for zinc coating was developed to apply superior coatings on oversized structures like bridges and boats to secure the protection of the metals. The zinc coating is a time proven application that assures maximum product life. Typically, the burnished brass finishes will change over time depending on their environmental exposure.įor our steel products, all of our components are fully zinc coated after final welding, drilling and machining are completed. ![]() Our true brass products, like all true brass products, require a more robust upkeep to maintain a desired color. It is a fabulous look and a quality time tested material approach. We also offer a true brass product with brass burnishing. Once the tone is set, we topcoat with a satin sheen clear coat to add durability for everyday use. For each of our projects we offer a palette of patina choices. The finish on our steel is a critical feature for the design richness and durability of the product. We have other patinas that chase the black and gray tones of worn steel. At times we mimic the tones of a burnished brass patina, yet we are able to stabilize that look on steel. Inherent to our patina finish is a randomness of color variation and texture. It is our effort to provide a unique, yet subtle, irregularity in the finish that gives a sense of age. Years of development have led to our unique patina offerings on our steel products. The true defining look of a “Jada” product would have to be attributed to our custom finishes.
