I am curious about this recipe, i do not want to waste any money so i would like to know if it has been tried with successful results. It is with activated charcoal ( kind used in fish aquarium), gun blue, house hold ammoniua covered in cheese cloth. Please post a reply. thanks, crispa queen

no offense, but it sounds like you just pulled that recipe out of your ass. and where the hell would one aquire gun blue? aluminum gun frames are blued through anodization.

this is to DISASTER MASTER whose ass did you pull that stupid reply out of ? I do not know a whole lot but even i know whast gun blue is It is a sealer for steel as in gun stocks and it forms a black oxide finish. AS to where you buy it any where there is a sporting goods section. Any one else that might have something useful and that makes sense ,please respond. Thanks, shelley67

Bullshit method alert, you can't make pseudo at home, nor can you make anything useful with gun blueing, besides a refinished gun.

heres an alternative hemisphere answer,,isnt metal blueing used for blueprinting engines,,as in you stain the block face blue,, then run the crankshaft on it and see what blue has worn off,,then machine it accordingly???

Ok everyone....It's official now. The gun blueing fish tank thing is a LIE!!

Don't waste any more valuable totse space to post anything more about it ok?

There should be some loud sirens and shit to go off when there is a "Bullshit method alert" This is an actual emergency....please remain calm and form a single file line!

Kirby: Gun bluing is a mixture of chemicals that rusts/oxidizes the steel surface. This oxidation protects against further ugly rusting. There are ussually all sorts of acids and nasty stuff in bluing compound.

Machinists use prussian blue, just a type of dye.
