When I use white diamond cutting rouge on a pierced silver
piece I get little lines that run out from the open area towards
the edge. What am I doing wrong?
Deb what’s happening is this; as you polish against the edge of an
openin g, the cutting media, what ever it is, (white diamond,
rouge etc) particles of the metal & buff build up on the edge.
Then periodically they break of f, for what ever reason, & are
carried by the buff across the surface of the metal your polishing.
Because they’re usually big chunks, when compared to the grit size
of the polishing material, they leave a scratch in the suruface.
The term for this type of action is aggregation scratching
(aggravation would be another good term, bg). The way to avoid or
at least reduce this action is to polish away from th e opening if
possible. If this isn’t possible, try polishing parallel to th e
edge of the opening. The last trick I know of to alleaviate this
conditio n is to use a clean buff, as little polishing media as
possible & clean the edges of any openings frequently to eliminate
any build up.
