smoothing marble

End of quote.
Try a stained-glass supply house. They sell them for use smoothing the
edges of irregular-shaped pieces of glass before joining the design with
lead. They are cast from silicon-carbide into about a eight or ten inch
long bar, oval in cross-section. They often are made with slight cutting
ridges on the surface, spaced much like the teeth on a file. They are
usually blue or blue-black in color, and they only come in one grit size
(unspecified, maybe 60?), but
because of the ridges they cut much faster on stone than a regular
60-grit stone when new ? but after the ridges have been worn down they
cut more slowly.
Speaking of rubbing stones, I have to add that when I go to Italy to
teach every few years, I usually get a selection of the triangular,
square, and cylindrical cross-section bar-shaped rubbing stones that the
Carrara stone-carving supply houses carry.
These green silicon-carbide stones come in 5 grits or more ? 36, 50,
80, 120, and 220(?). I find the 36-grit triangle and round especially
handy in the rough stages of smoothing hard-to-reach areas, and I usually
only purchase the coarser couple of grits because I can use other methods
(steel files, diamond files, sandpaper, etc.) if I desire further
smoothing.
I have not seen anything but rectangular rubbing stones in any of the US
supply house catalogs I buy from, maybe somebody else knows if the
three-sided or cylindrical stones are available in the States?
Good Carving to You,
Don
