Color erasure: bad ano?
Posted by admin on September 2nd, 2009 at 08:32pm
Proper anodizing is supposed to be pretty hard; I’ve dropped it or taken steel wirewheels to it and seen little effect. This surprised me.
here are two anodized + dyed pieces that tapped against each other repeatedly. one is rounded, the other is somewhat sharp at the edge. both weigh very little because they’re about 4" long.
the rounded one tapped the sharp edge of the other one for a day or so, and developed this colorless area where the contact happened. there’s no scratch you can feel in the finish, but the color looks erased.
this is bad, because this was part of a gift. did i do something wrong, and if so any ideas how to prevent?
thanks all!
