POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

Getting ready for the big game on Sunday . Taylor is coming to Baltimore ! 1705969645048.pngI ordered 5 lbs of rusty nails to drive thru my private parts while she is on , and :you suck: Taylor .
 
I decided to rust blue it instead and finished it up with BLO. It turned out so nice I refinished my grandfathers Athol 614 while I was still set up.

Turned out really nice!

Where do you get the rust bluing compound? Is this something you made, or purchased? The first time I heard of it was a LONG time ago, and have been intrigued ever since. Have a recipe, but have never actually tried it.
 
I use this stuff. Expensive but gives a very good finish

You make it yourself. I make mine from some table salt and hydrogen peroxide. I use the 12% peroxide. If you search HM, there are several threads on it. Search for @MrWhoopee or myself, those are the two I remember. You build up thin layers of rust, then convert the rust to blue by boiling the piece in water. It takes quite a few repetitions, but it does work. Here's some tee nuts I made and blued.

For those who don’t have prior experience with cold bluing, I recommend starting out with Birchwood Casey Perma Blue. The Super Blue has more selenium in it and is generally harder to work with.

This stuff is and example of the selenium based bluing compounds. This is very different process from rust bluing. Rust bluing is a slow process requiring many applications of compound, mechanical cleaning, etc.

My first recollection of a rust bluing compound was that it used nitric and hydrochloric acid and iron filings to make the compound. The iron saturated compound is allowed to settle, and drained off the top of the remaining iron filings. It is then kept in a brown bottle (light sensitive???), and applied daily. Before reapplication application, the nominal surface rust formed by the pervious days compound is removed from part.

I don't pretend to understand the chemistry.

It's supposedly a very high quality bluing, typically only done on high end firearms due to the time required.
