Apparatus and method for surface treating vitreous materials with treatment gases to form a metallic oxide surface condition on the vitreous material. The apparatus, which is preferably an enclosure having an entrance and exit end and is mounted over a conveyor belt, incorporates manifold means for distributing the treatment gas within the enclosure and also heating means for maintaining the interior of the enclosure above a critical temperature. The method comprised is applying a treatment gas to the vitreous surface while maintaining the gas above a critical temperature substantially below the pyrolitic decomposition temperature which is necessary to accomplish the actual surface treatment.
