Abstract: The present invention provides a stain-resistant glass and a method of making such a glass. In accordance with the method of the invention, SO3 is applied to the upper surface of a sheet of float glass in an amount sufficient to reduce staining of the glass. In a preferred embodiment, the oxygen-containing gas and SO2 gas are supplied in a lehr adjacent the float bath at a temperature of at least about 800 DEG F (about 425 DEG C). In one aspect of the invention, a hood (30) having a gas delivery system (40) is provided, with the hood defining a downwardly open enclosure and enclosing a portion of the delivery system. The hood is optimally disposed above a ribbon of float glass (25) in an annealing lehr (20) and the delivery system may include a sparge pipe for delivering either SO2 or SO3 gas to the hood.

Abstract: The present invention provides a high transmittance, low emissivity film stack having an overcoat of an oxide of a metal chosen from the group of zinc, tin, indium, or bismuth, or an alloy including one or more of these metals, the oxide being applied in a thickness sufficiently low as to have no significant affect upon the optical properties of the coated substrate. That is, if the overcoat is lost through abrasion or chemical attack, the loss will not significantly affect the optical properties of the coating. The resulting film stack exhibits significantly enhanced durability as compared to a film stack without such an overcoat. In a preferred embodiment, a film stack of the invention includes at least one reflective metal layer, an outer, scratch-resistant metal oxide overcoat, and a metal oxide layer between the silver layer and the overcoat which is less scratch resistant than the overcoat.

Abstract: The present invention provides a coating for a transparent substrate which exhibits a neutral color through a wide range of angles of incidence of light. The coating employs a base coat (20) adjacent to the transparent substrate (10) having a thickness of no more than about 275 Angstroms and may include two reflective metal layers (30, 50) having an intermediate layer of an anti-reflective metal oxide therebetween (40) and an outer anti-reflective layer of metal oxide (60) over the second reflective metal layer (50). If so desired, the coating of the invention may include an abrasive-resistant overcoat as its outer most layer (70). This overcoat is desirably formed of an abrasive-resistant metal oxide, such as zinc oxide, applied at thickness which does not significantly affect the optical properties of said coated substrate.
