I need to make a bunch of molds in sandcast bronze and would like to
know the kind of sand
to get for finest detail/smoothest finish . They won't be complex , or
even 2 part sand molds, probably just bronze poured onto a flat cope
that has an depression in it and a dam built around the depression .

thanks

DS
