ABSTRACT OF THE DISCLOSURE An ingot mold has been devised which instead of utilizing a full protective thickness or section of sand within the spacing between a metal core bar and a metal flask, employs a refractory lining for the flask and a refractory coat for the bar that respectively have a cross extent or thickness that occupies a greater portion of the spacing than the casting sand. The casting sand is utilized as a minimum inner thickness to define the casting mold and as imposed between the refractory lining and coat.
