MetalMuncher Posted October 11, 2008 Share Posted October 11, 2008 Hello everyone. I need some help with my finishings. I need to know when to apply the finish. Do I heat the piece up after it has been quenched and tempered? Wont that destroy the temper? I have obtained a nice finish (brownish in color)by heating an un tempered piece and applying motor oil. Will the color of hydrogen peroxide be different? Thanks for your help. Quote Link to comment Share on other sites More sharing options...
NateDJ Posted October 13, 2008 Share Posted October 13, 2008 Not exactly sure of the answer to the first part but i know Hydrogen Peroxide will cause the piece to rust like right now! Worse than sea water. Quote Link to comment Share on other sites More sharing options...
Maisch Posted August 13, 2009 Share Posted August 13, 2009 i dont know the answer to your questions. but i have soaked a project in a copper sulfate solution for about six hours and it gave it a rusted finish but it sorta rubbs off. copper sulfate is used to melt ice i have heard and it is blue and looks like small crystals.

ThomasPowers Posted August 13, 2009 Share Posted August 13, 2009 search on patination and you can learn a LOT! Yes for a blade you need to use a process that keeps it under the tempering temp. Quote Link to comment Share on other sites More sharing options...
MattBower Posted August 13, 2009 Share Posted August 13, 2009 Yeah, if you're talking about the carbonized oil finish, it's not really ideal for blades. Rust bluing is a favorite of mine for fittings and such. I'm not sure how durable it'd be on a blade, though. Quote Link to comment Share on other sites More sharing options...
DennisG Posted September 3, 2009 Share Posted September 3, 2009 my two cents..... bees wax at a heat not too high but able to melt the wax nicely. Quote Link to comment Share on other sites More sharing options...
Charlotte Posted September 5, 2009 Share Posted September 5, 2009 Plumb brown finish and other similar finishes have been used on guns for a couple of hundred years. Essentially it is a controlled rust finish. Look on some of the Blackpoweder sights for recipies. I have helped a friend formulate a number of finishes for damascus shotgun barrels. Most required two different acids, a couple of metal oxides, and a very dilute solution applied over a period of weeks with intermitant carding(brushing with a stiff bristle bursh) . After a period of weeks the result was a beautiful finish maintained with linseed oil. Not what I like on a knife but beautiful on a 19 th century shot gun, Quote Link to comment Share on other sites More sharing options...
