I'm currently working on trying to get a bright blue
Color on some parts of a post m 70. I at this point I'm getting a
Nice blue black color using stump remover and 500
Degrees on a propane stove. I just can't seem to reach
A bright blue. Is my heat to low or do I need something in
The nitre solution to reach the peacock blue? I'm also
Wondering if I use my casting furnace will it ruin it for casting
Lead if I don't get all the potassium nitrate out? Thanks for
Any help on this.
