Hi Tim! The solution is made from a small amount (doesn't have to be precise, maybe 1/2 teaspoon) of a chemical called cupric nitrate, or Cu(NO3)2, dissolved in some distilled water. You can paint the solution onto any metal surface and then heat the surface up with a small torch or heat gun, or put it on a hot plate, to cause the water to evaporate and leave behind copper oxide. It takes a few coats but it can be finished in a few minutes which is way better than the salt and vinegar type patinas that take forever and don't offer you much control. I bought my cupric nitrate from a supplier online and it is pretty inexpensive, here is the link: www.sciencecompany.com/Cupric-Nitrate-100g-P6382.aspx . Also be sure to read the safety data sheet for it, it is not extremely dangerous, but the fumes from the evaporating water also contain a small amount of nitrogen dioxide which can cause sickness or lung irritation so I usually do it outside with a mask on. Also once the patina is applied, only wet sand it if you're going to sand at all, so that you don't breathe in any copper oxide powder. I usually don't sand though because people love the crusty appearance.
@@jackbogliolijewelry32 O wow! You truly made my day! Thank you so much! Really appreciated!!! Keep up the great work you do! This was the most helpful info I've been looking for ! THANKS!!!
Amazing and effortless technique, I will try that instead of messing with sulfuric acid and ammonia
amazing video,,is that copper or bronze..?
Hi Jack, would this also work with a steel or stainless steel sheet?
I've been looking for something fast as this, how do you make the solution?
