These are the molds, arranged so there's plenty of room for the
ladlemen (or ladlepersons in some cases) to move around for the pour.
The sand is of course a safety thing, so any spilled hot iron- and yes,
there were more than a few spills- wouldn't spall and damage the
concrete, or go running along and try to melt it's way into somebody's shoe. The molds are plain sand- local glacial sand-
mixed with a commercial binder not unlike an epoxy. Multi-part molds were banded together with crate strapping.
