Re: pumice as sculpting medium

That's what I thought concerning the "hell on steel tools" and thanks =
for
the reminder about the silica.  We're back to the best idea being always
wear a mask and also get the dust away before taking off the mask.  I
believe Eugenia mainly uses it as a sand ingredient to make a kind of
plaster but the sand dust, of course, is not safe to breath.

Hi all,
I just need to add one note of caution regarding carving pumice. It is=20
basically pure volcanic glass, so the dust is pure silica. Anyone who =
works=20
with pumice needs to use a good dust mask. Other then that, it is a real =

cool stone to play with!
The first stone carving class I attended provided some pumice stone. One =

fellow attacked his stone with a brand new set of Italian riffler files. =

About half way into his project all the files were worn out. Pumice may=20
carve easily, but it is hell on steel tools.
