A safety feature...
Not so much documented as custom and practice. All this sort of thing stems
from casting technology from the beginning of the industrial revolution: suppose
you want to make a cast-iron locomotive wheel; you make one in wood (called a
pattern), you pack that in sand in a box, then split the box and take the
pattern out so you can use it again, then you pour molten iron into the sand
cavity...
