A fender used in the " float " glass process for halting the lateral flow of molten glass, comprises at least one hollow channel member 20, having a face 17 engageable with the molten glass 16, the face being extended to form a foot 22 which in use extends below the level of the molten metal, the hollow 24 of the channel member including a groove 25 extending into the foot to facilitate cooling of the face 17. In use the hollow 24 is filled with molten metal and cooled by cooling fluid passing through a pipe 28. The lower surface 23 of the channel member may be provided with a layer of thermal insulating material 133, or alternatively (Fig. 4, not shown) the lower surfaces of both the foot and channel member may be covered by thermal insulating material. The channel member is preferably of graphite and the thermal insulating material is " Fiberfray " (Registered Trade Mark).
