How do I get a more aggressive parkerizing finish?

2004

I'm using a basic parkerizing process using phosphoric acid, manganese dioxide powder, water and 0000 steel wool [affil. link to info/product at Rockler]. The results have been nice but I'm looking for a little more aggressive finish using the same chemicals maybe in a different proportion or different procedure. I've seen some parkerizing that has a crystalline appearance and that's pretty much what I'm looking for: Even a little pitting would work for me.

Thanks,

Try Zinc Phosphate Parkerizing. It is grainy in appearance and can be Blackened.
