One gallon of a Traditional Black Patina generally covers 200 sq. Traditional Black Patinas are sold in 8oz., 32oz., 1 gallon, and 5 gallon sizes. Layering the patina with multiple light coats will gradually darken the shade and allow you to control the uniformity of the finish. Dilution with distilled water is recommended for a smooth light grey finish. The patina will be black and often mottled if applied at full strength. Zinc Grey Patina creates a grey or black patina on zinc or galvanized steel. Stainless Black Patina works best at full strength, but can be diluted with distilled water if desired. On stainless steel, this patina will be blue grey at first and then darken as more coats are applied. It is not recommended for other metals, but on zinc and galvanized steel, it can produce a red-brown or weathered black patina. Stainless Black Patina is made specifically for stainless steel. On stainless steel, it must also be applied hot and will produce a red, black, and brown patina. On aluminum, it must be applied hot (180-200☏) and will create a brown finish. On zinc and galvanized steel, it will produce a dark brown to black patina. Slate Black Patina will darken bronze, brass, and copper in a similar way. Slate Black Patina can be diluted with distilled water for lighter coats. This is a fast 3-5 minute reaction that is arrested with water. On iron and steel, it will produce a black patina with some brown showing through the finish. Slate Black Patina is a versatile black finish for use on most metals. Second and third coats darken the patina to a rich antique black. On bronze, brass, and copper (diluted 1:1 with distilled water), the first coat produces a beautiful brown patina. Reapplication results in even more warm color with great adhesion. On zinc/galvanized (full strength), the first application establishes a bronze/brown finish. On steel (full strength), one coat makes a blue/black oil slick finish. Additional coats create a solid black that does not rub off easily. On aluminum (full strength), the first coat produces a fast grey/black finish. Rust is slower to develop compared to other black patinas which allows greater flexibility when applying a sealer. This patina works quickly and has excellent durability. Traditional Midnight Black Patina reacts on aluminum, bronze, brass, copper, iron, steel (not stainless), and zinc/galvanized. It should not be diluted unless you are working on the Metal Coatings. Black Magic Patina does not work on stainless steel or aluminum. On zinc and galvanized steel, it creates a weathered black patina. Rust will develop if a clear sealer is not applied to the completed finish.īlack Magic Patina works similarly on bronze, brass, and copper to darken the metal. The first coat will be dark grey, but the finish will become black after a few coats. It takes only 3-5 minutes to develop and does not produce the quick rust that you normally see with other blackening agents. However, it's deferentially heat treated, which creates a hardness line similar in appearance.Black Magic Patina creates a beautiful, rich black patina on iron and steel. (And yes, I know that my hatchet does not have a real hamon. You can see that the lines on my bushcraft knife are much thicker, because I left the mustard on it for a longer period of time. That is because I didn't leave the mustard on quite long enough. The main visual difference you can see between my fake and the real hamon is the depth of the line. In other words: Part of the blade is harder than the other part, and the intersection point between hard and soft steel is marked by a very classy looking line. The change of hardness in the metal is visible in a dark line running across the blade the hamon. The blade would end up with a very hard cutting edge, and a soft spine and back. Japanese smiths would coat the spine and the back of their blades with a clay mixture which, when quenched, caused the part of the blade coated with clay to cool down much slower than the bare metal. The Sculpt Nouveau stainless black traditional patina would be used if more. A real hamon line is created during the heat treatment of the steel. This stainless black patina will provide a more uniform, straight gray appearance. Well, the difference is actually pretty big. By this time some of you (the newbies) are probably wondering what the difference is between this hamon-looking-line I just created, and the real deal.
