For the manufacture of thick glass by the float process, fenders are provided for defining a channel down the molten metal bath and each fender comprises a hollow channel member having a flat face which is not wetted by molten glass and which face extends downwardly as a foot for immersion in the bath, there being a groove in the foot near the flat face to facilitate heat extraction from that face when cooling fluid is circulated through the fender. |
