I'm trying my hand at Carbona bluing. Or something like that. I was reading upon the process and it sounded a lot like my gas barbecue. 5 hours at 570 or something like that in a gas oven. Maybe a little charcoal in the chamber depending on who writes about it. So I pulled the .357 of my 2nd gen Colt because I'm turning it into a 45 anyway. Soaked it in vinegar for 10 minutes or so to remove the finish and into the barbecue it went. Heres the before pics. One the gun and in the barbecue. It still in the barbecue. Been there 5 hours so far. Its got color definitely but its not even yet. A few more and we'll see what it looks like.
