On dried clay I use the sponge back sanding pads from silverclay.co.uk
They're better when the clay clogs them up a bit no scratches
The sponge back makes for lovely slightly softened edges.
A gentle smooth over with a baby wipe finishes the pre-firing prep.

I don't really get scratches, by the time I'm at the finest grade it's pretty smooth. You have to be very gentle
A baby wipe will smooth any little marks and also seems to help get a better final shine (post firing).
Must admit though I try and make sure the clays worked enough in it's moist state and that it's smooth before drying.
On f.print pendants I often only sand the edges and the top gets the lightest of touches (if at all) before baby wiping.

Hi, Ive been reading and reading about removing scratches from PMC and have followed everything above from start to finish as advised above etc, yet i STILL have scratches on my finished piece. I have tried finishing with both the 3M papers and the Spectrum papers on 2 different pieces to see if its one or the other, but scratches are still there. Ive bought the silicone polishing tips, and used them in all grades, and they seem to mark my silver. Whatever I do i simply cant win!! Maybe Ive got my dremel on too fast? I've used every kind of tip from fat to thin, and worked through the grades.
Can anyone please please help? Its had me in tears again today!!
ps. tumbling is doing a wonderful job, but I is no good for fingerprints (
if I'm using PMC (and I do only use it for the fingerprint rolls I make) I do an initial clean using 3M radial wheels, use a superlight touch, don't press! Then I just use a basic polishing rouge on a polishing mop. PMC is so soft that unless it's a deep scratch from the dray stage, it just polishes out. I've also found that I can burnish scratches down enough to polish them out either with abrasive wheels or a mop.
Thanks.. I'll give that a try
