    Sodium Silicate is used as the binder that "glues" the sand together in cores. For example, imagine making a cannon. The bore (hollow section) of the cannon can be formed by a core. The hardened sand core goes into the cannon mold so that the molten metal will form the cannon body, but be blocked from filling the center.
