Garnet abrasive


#1

I’m the recent recipient of several pounds of garnet abrasive,
typically used in water-jet cutting machines. Is there a use for this
as a jewelry abrasive? If so, how?

Thanks,
Jamie

Do you know the particle size of the abrasive? You could probably
use it instead of ceramic cones for cleaning up castings or for
frosting glass.

the abrasive is probably too coarse for a tumbler- particularly if
you consider it would be as though you added sandpaper to the inside
of the drum- garnet does come in many grits however and the finer
grits that are common are 200-1200- the lower #'s (40-60, etc.) I
would expect lots of scratching on soft castings of 18-24 kt golds (
regardless of colour of the gold alloy excepting perhaps white gold
as the nickel in it is fairly hard even at 18 karat). I would not
use it in a large particle size for fine silver at all especially if
there are details that are not deeply carved into it…

no abrasive is ready for use right out of the box.

take some of it to glass plate, add some oil, and work it with
spatula like a dough. The grains would crash against each other and
form proper working consistency.
