Abstract

1392608 Floater or skim bar for glass furnace PILKINGTON BROS Ltd and H F FRIEND 16 Oct 1972 [3 Nov 1971] 51173/71 Heading C1M A skim bar or floater 10 for use in a glass melting furnace comprises a body 11 of non- metallic refractory material (e.g. alumina or fused silica) at least partially encased with a refractory metal 15 which is resistant to molten glass, and means for retaining a static pool of molten glass 18 on an upwardly-facing surface 19 of the metal. The refractory metal, which may be platinum or a platinum alloy with rhodium or iridium, is protected against oxidation by the molten glass. The metal layer is preferably no more than 1 mm. thick. The static pool of glass 18 may be retained on the surface 19 by peripheral lips 16, 17 of refractory metal, which lips may be discontinuous, by a dished surface shape, or by clinging to a mesh of refractory metal. The body 10 preferably is rendered buoyant in molten glass, e.g. by comprising cavities 12.
