摘要： An improved apparatus for producing a glass ribbon and an improved method for subsequently coating said glass by pyrolytically depositing a metal oxide coating thereupon. The glass is produced in a molten metal float bath having a reducing atmosphere supplied at a slightly positive pressure which is comprised of a mixture of nitrogen and hydrogen gasses. The slightly positive pressure of the reducing atmosphere within at least one lock chamber of the float bath is reduced by venting at least one lock chamber to the outside atmosphere through apertures of reduced size each of which is located in a lateral exterior wall of at least one of said chambers which is separated from the float bath by at least one other of such chambers. Additionally, blower means may be provided to direct an inert antiflame gas, such as nitrogen, toward the base of an airtight curtain at the exit of the outermost lock chamber in order to reduce or totally quench the flames attributable to the burn-off of that portion of the reducing atmosphere which escapes therefrom.
