Abstract
A tin alloying metal seal is employed at refractory joints about the bottom of a float glass forming chamber for containing molten tin upon which glass can be formed in order to prevent leakage of tin through interstices in the refractory, or between refractory pieces, by forming an alloy with molten tin reaching the metal seal which has a substantially higher melting point than tin.
