I disagree -- I'm guessing you could be off by as much as a factor of
two between mineral and coral sand, which is a pretty big error.
None of these replies were meant to be pedantic or encourage pedantry
in the label itself.  I've seen schoolkids in museums copying
information for reports &c from labels -- they are taken very
seriously by the public & I would hope that we who write them
wouldn't engage in too much hand-waving.
