Gentler or more environmentally safe chemicals may only need a quick rinse with clean water before your metal is safe to handle barehanded. After appropriately mixing the ingredients, you have to apply the mixture on the metal for a few days repeatedly. Spray that once a year, you should be fine. Remove all patination and rust to prepare the surface. A cheap but very effective recipe involves a mix of salt, vinegar, and peroxide. It is best to make a fresh batch each time. I would recommend blasting thing a torch until bright orange-yellow (2000 degrees F) to allow fire scale to form. Re-season your pan with your method of choice — and remember to give it a good swipe of fat after every use. The golden and bronze finsihes can be clear coated but will eventually darken with age. Clear paint is not an option due to the heat from the fire. Some chemical treatments may need to reach a certain temperature to work best. It is usually necessary to add a small amount of acid to the copper solution so to "activate" the steel surface by removing residual oxides, and assist in keeping the copper salt dissolved in the process. The copper patina makes use of a solution of copper chloride, copper sulfate, that is slightly acidified. This will remove build up in difficult to reach nooks and crannies. Is the color of a knife’s patina important ? Many of these are formulated to work well on copper, brass, and bronze. The whole process, which I found incredibly cool, took only a minute or two. Copper Patina: The ingredients for copper patina are the origin of its name. You can also sandblast then brass brush, and finally burnish steel to get a golden appearance. I do have a question that I hope you can help me with...After I've rusted my products, they become so dusty and leave residue on everything. Can you suggest a way to stop the process and avoid the rusty dust? My Chemistry teacher showed me how to silver-plate a copper penny without heat or electricity. Same thing happens when you have a thin film of oil on water. In extreme cases though it might be best to dunk the steel in the concentrate right out of the bottle. Be mindful of heat sources and hot metal, A slightly acidified solution of copper sulfate or copper chloride. Your chemical may have come with a separate neutralizing agent, but in many cases, baking soda can be added to neutralize chemical solutions. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/76\/Patina-Metal-Step-1.jpg\/v4-460px-Patina-Metal-Step-1.jpg","bigUrl":"\/images\/thumb\/7\/76\/Patina-Metal-Step-1.jpg\/aid8062956-v4-728px-Patina-Metal-Step-1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"
