Yep. Just wondering out loud, mostly in jest. One reply (Father Haskell)
however did suggest Diatomaceous earth (food grade) as a possible sub
for 4F. Local hardware store carries it and perhaps I should experiment.
DE is calcium based and pumice is silica,

DE _is_ silica -- that's how it kills bugs, by abrading the
wax from their exoskeletons, which dehydrates them. It's
hardly food grade, though it's harmless to furry household
creatures.

For French polishing, the only substitute for FFFF pumice
is FFFF pumice. For an after-cure rub, take your pick of
fine abrasives.

so not quite sure what effects
will result from stains, Poly, lacquer, shellac, Varnish, or grit on
grit finish sanding/ scraping. Will it color differently as seashells do
when oiled? Will it react badly with clear finishes? Will it even work
as fill? ...?

Never read anything on this sort of an application for DE, so unless
someone can save me the trouble I'll just have to give it a shot myself.
Anyhow, sounded like a good idea and worthy of serious consideration.

Thanks,
