Keeping in mind the fact that we are talking about play sand, the kind
that people buy especially for the purpose of allowing their children to
play in for hours on end.
It was banned for use for sandblasting because it does break up small and get into your lungs.

Agreed that silica is a health hazard, but any dust you create
is also. That said the best casting sands today are made with 'Olivine'

from your patterns, wearing a particle mask or respirator with good
filters is the only safe way to handle dust, smoke, fumes!
