Thank you all!
I hope maybe someone can help me out though...
I just had a look around (searched all over)
and couldn't find any tips/hints on finishing mokume gane.
I've never used it on a knife before,and am wondering if there's a way to finish/seal it so it doesn't develop a tarnish or patina.
(it's copper and brass mokume).
I have the ferric chloride,and (somewhere) have an email explaining how to cut it with water for etching the mokume,
but nothing about the final finish (after I sand it to about 1200grit then polish it).
Thanks guys!
