I could imaging granite "dis-aggregating" like it does when you do a
thermal finish and the individual grains break free (pop) from the
adjacent ones. In a fire I could image large areas rapidly turning to
coarse sand

THIS is interesting. What do the remains look like after the granite
"melts?" Do other building stones act the same way?

Granite does terrible in fires - just "melts" away.
Sandstone does not.

See message below. I know brownstone was never illegalized, but anyone
ever heard anything about brownstone burning (except perhaps in Mel
Gibson apocalyptic movie)?

Dear Mr. Gray --
Your brownstone restoration piece in today's Times was good
reading
-- thank you! I have a question, however, concerning an aspect
of
brownstone construction. I read somewhere long ago that
brownstone
burns -- like charcoal -- and was banned by New York's building
code
at some point in the early 20th cent. It seems that when a fire
in a
brownstone-clad building was put out it would sometimes
re-ignite
from the still glowing brownstone cladding. I'd be curious to
know
if you turned up anything in this regard during your research
for the
article. And if the law is still on the books the restoration
of 797
Madison would appear to be in violation of the building code.
Thanks again,
