  • Stain-resistant glass making method
    Patent number: 6349569
    Abstract: The present invention provides a method for making a stain-resistant float glass and an apparatus for carrying out such a method. In keeping with this method, SO3 is applied to the upper surface of float glass in an amount efficacious to materially reduce staining of the upper surface of the glass. Optimally, SO3 gas can be applied directly onto the upper surface of the glass. An apparatus of the invention generally includes a downwardly open hood positioned above the upper surface of the glass and having walls defining an enclosure. SO3 gas (either as such or as a reactive mixture of S02 gas and an oxygen-containing gas) is delivered through a delivery tube to the enclosure.
