Do any of you knife nuts know a way i can darken copper so it will stand out better in mokume? any help would be welcome.

Go to your local gun shop and pick up some cold bluing solution...on copper it produces a dark brown patina.

What mix is your mokume? You can use plain household amonia to darken copper. But it will also darken brass And many other copper alloys.

Good old Ferric Chloride worked fine for me.

Hi,
Baldwin's Patina from Reactive Metals is great. Stan Fujikawa (sp??) turned me onto this. It gives great contrast between the various metals.

I like baldwins patina or the traditional rokusho patina with niage base from www.reactivemetals.com

Gday guys,
Good ol' lemon juice plucked straight out of the back yard works pretty good for me.

Cheers Bruce
