Tumbling rings (or anything, for that matter) actually burnishes the
metal by compressing it instead of removing metal.
Anything that has already been shined or patinated, etc. would not
do well in the tumbler for very long at all. The small pieces of shot
are actually hitting one another and anything else in there. The
force of tumbling will create ‘dings’ in the material being tumbled.
We tumble pieces for about 24 hours minimum. This gives a more
complete tumbled finish, but remember it is burnished and not
polished. Pieces that have small recesses, that are very odd shapes
or not-polisheable for any reason but are sturdy might do well with
I’m not sure if you were trying for a certain effect, but tumbling
something that is finished will undo all your work (as you found
out…sorry, it really is horrible to have that happen.) Likewise, if
you have a patina on a piece, tumbling will impact your finish. Now
you know what it looks like…take pics for yourself as a reminder of
what happens. Maybe take some pieces as an experiment and tumble them
for a while and see if the effect is better than what you have now.
The pock marks will be more smoothed by longer tumbling. That way
you’ll know what the finishes look like if you ever want to use them
to your benefit.
By the by, I don’t know if there is a problem with my computer or
your site, but the address comes up as not found. If there’s a typo,
please email so I can have a look.
Best of luck with your pieces,
