Ok lads, I have just spent nearly an hour searching through previous messages and have decided to just ask outright. I am currently fabricating a set of bearing standards and wish to treat them with either a very dark blued finish or parkerize them. Now I have used an emersion solution before that turned steel black or grey depending upon the exposure, on small nuts and bolts etc. The standards I am working on have been silver soldered together to form one lump. What type of finish(s) can be used that will color the steel as well as the soldered up joint? I've never done parkerizing before so have zero experience with that process. I'm not looking for a super exotic method here, merely something that will give satisfactory results with a low cost of course. Any suggestions? I apologize if this question has been raised before but am looking forward to hearing all about anyones previous adventures in the matter.
