OK, I am fiddling with a new ( to me ) antiquing technique for knife blanks. I sand blasted 6 blades, cold rust blued the blanks, and then put them in bleach to etch. The antiquing was supposed to take 20 minutes. I pulled the blades out of the etch at 20 minutes. Scrubbed them in soapy water and nope, not what I expected.
The blades had brown gunk all over them when I pulled them out. When I scrubbed them off the bluing was only partially removed. I put them back in the etch and pulled them out for a cleaning on the hour every hour for 6 hours. Still not what I was expecting.
I think I am missing something and was wondering if anyone here using this technique to create an antiqued blade.
I used cold bluing as the coloring compound, I used standard laundry bleach as the etch. No dilution with water. The temp was right around 55 degrees.
