<p>A tank for containing a bath of molten metal in a float glass furnace has a wall formed by a plurality of juxtapositioned prefabricated refractory members. The joints between the members define interstices. Interstices are also being defined adjacent other faces of the blocks. Powdered carbon, alumina, chromium oxide, a carbide or nitride not wettable by molten metal at least partially fills these interstices to prevent the flow of molten metal therein so as to prevent raising of the blocks from their assembled positions by the flow of molten metal behind the blocks. These are in the interstices between the particles of the powder flow paths having restricted cross-sectional areas. The object of these restricted areas and the surface properties of the powder material is to prevent penetration by molten metal.</p> |
