Bar
A flask consists of sides, ends, and bars (cross-bars). The latter connect the sides, and form spaces in which rammed sand is held securely. When flasks exceed a certain size, the sand's adhesiveness is insufficient for its own support; it is then that bars are introduced to lessen the space, and thus restore their usefulness; in other words a large flask with bars is simply a number of narrow flasks, side by side, and raised a little higher than the sides to admit of a sand junction being made underneath, and thus secure a continuous sand surface.
