One of the most delicate finishing processes is the bluing operation. Bluing
is not a coating, it's a rusting process. Our hot tank solution uses a caustic
solution of Nitrate salts and is heated to exactly 292 degrees F. Since bluing
actually highlights imperfections in the metal, special care must be exercised in
the preparation and polishing.
We begin with block polishing to remove imperfections while maintaining sharp
edges and crisp lettering. Block polishing also helps prevent the rippling effect
created by uneven buffing. Our polishing proceeds through 240, 320 and 400 rouge
grits to duplicate the factory production finish. To produce our high gloss Mastercraft
finish, we continue polishing with 500, gray, and finally white (equal to 2500 grit).
To achieve a low gloss matte finish, the metal is block polished, glass bead blasted
and then finally blued.
