It simply sat until the next morning when the procedure was repeated. Leaving for work and have a nice coat of rust when I got home. ![]() The nice thing about this method is that I could coat the barrel before ![]() I have used the latter method on my guns and only 3 applications were required. While if you prefer a more rustic coarser surface you can use a 12 hour cycle. Tastes run toward a "gentleman's" fine surface they recommend a 3 hour cycle Instructions indicate two different types of browning available. I took them at their word and had no problems with the solution taking. Operation and then you can still handle the parts normally, no gloves required. The Laurel Mountain formula allows you to do a simple degreasing Is done you can never handle them with your bare hands until the job isĬompleted. Solutions is that you must completely degrease the parts first and once that One of the problems with most blueing and browning This last one is the one that I have used. I used the box method on a few muzzeloaders I built years ago and for the natural effect you couldn't beat it.īrownell carries a number of browning solutions: Pilkington, Mark Lee, and Here is some more info, that I dug out of my archives. I have also read about people who spray copper or bronze paint on steel, or better yet, electroplate a thin layer of copper, and then use the classic patina forumlas for blue and green.įINISH: I've had best luck with clear spray lacquer when cool. OTHER COLORS: I have seen ads for dyes to make steel blue, green, or other colors. HIGHLIGHTING: Using, say Bismuth on top of Birchwood Casey, you can take some of the Bismuth off with a scotch brite pad to show the darker color below. If you overheat you can turn the Sandstone effect into Granite.Ĭolors: Light grey w/ white highlights: Start with Birchwood Casy, then spray Bismuth. This stuff is expensive, even on eBay.Ĭolors: Yellow to Sandstone to Granite: Start with Bismuth spray, heat until it is a little past pure white, then alternate Ferric and Bismuth. Brush it on or soak piece in the solution until you get it the color you like, then rinse with water. This is applied cold - and so is usually done before you apply the hot patinas. used 2 gallons distilled water).īirchwood Casey M80 (Colors are gray to black) also Birchwood Casey gun blueing (grey-black-blue). I have to shake the bottle a lot before and during spraying. I could not find the colloidal silica so my solution clumps up. If you can get it, add 3 0z colloidal silica. The other colors are easy.īismuth Nitrate (Colors are white through gray to dark grey) 225 gm bismuth nitrate 75 gm stannic oxide 75 gm titanium dioxide 1 gallon distilled water 15 drops nitric acid. Pink is hard to get - you need a minimum of heat, spray the Ferric, and then stop heating. If you overheat (burn) it then you get dark browns. They are for a gallon of water - I would scale the formulas down to a quart because a little goes a long way.įerric Nitrate: (Colors are pinkish red through rust red to dark brown) 80 gm ferric nitrate disolved in 1 gallon of distilled water. SOURCES: Also FORMULAS: There are only three - but you can get a wide variety of finish colors. The beauty is that if you don't like the result you can always wire brush it off.

Heat the metal, give it a squirt, and if the water boils off right away the temp is about right. ![]() ![]() Patina's are usually sprayed on - so you need some spray bottles. Acetylene torches are too hot - best are propane weed torches. Most patina's are applied hot - metal needs to be around 400 F. You can only patina mild steel - not stainless. Wear at the minimum a fume mask - respirator style is better yet.ĪPPLICATION: Metal needs to be clean - wire brushing is OK. Work in well ventilated area, preferably outdoors. SAFETY: Wear chemical handling nitrile gloves - can often find them at Home Depot, Lowes, etc. While there is a lot of info available for copper, bronze, and brass there is none for steel that I've found.
