lyuv Posted December 5, 2017 Share Posted December 5, 2017 Hi all, A buddy and me made 2 damascus blades. One etched in vinager and the other in FC. After a short time of very moderate kitchen use (cutting and gentle washing), the colors are almost gone. Re-etching works, but is that the norm? I expected the colors to be forever (short of polishing). Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted December 5, 2017 Share Posted December 5, 2017 how long did he etch, is he cutting acidic materials? does he clean his blades or allow them to remain dirty for long periods? Quote Link to comment Share on other sites More sharing options...
Latticino Posted December 5, 2017 Share Posted December 5, 2017 Also, what steels were used for the pattern weld? Some combinations are very subtle, and some a lot bolder (i.e. mild/high carbon steel verses 1084/15N20). As Steve indicates, the depth of the etch can have a great effect on it's permanence. In my recent experimentation with pattern welding I have found that multiple short etching baths with vigorous brushing off of the oxides in between each dip (I use an old toothbrush) seems to be more effective than just a long soak in the acid.
