This specification is directed to a glass spandrel product which finds particular utility as a device for enclosing a building. In accordance with preferred teachings of the invention, the new product includes light-transmitting glass sheet having first and second surfaces. A tape is also provided which is attached to one of the surfaces of the light-transmitting glass sheet. The tape is formed from an organic based strip material having good elongation strength and tensile strength characteristics and an organic adhesive which bonds the strip material to the surface of the glass sheet. The organic based strip material may be of a selected color so that the glass sheet has a desired color when viewed through the surface not having the tape bonded thereto.

Glass spandrel product

This specification discloses a method of forming a decorative surface on a body of glass. The steps involved in the method are initiated by a step of forming a metallic oxide film on the surface of the body of glass to be decorated. At least the portion of the body of glass having the metallic oxide film thereon is immersed in an etchant acid bath. Thereafter the body of glass is removed from the etchant acid bath when the etchant acid bath has reacted with the metallic oxide film to create a decorative surface on the body of glass. The decorative surface includes a plurality of elongated lines generally intersecting with one another. In normal cases the metallic oxide film is a multicomponent metallic oxide film.

Method of forming a decorative surface on a body of glass

A new article of manufacture is disclosed. This article includes a glass substrate having at least first and second surfaces. A coating is placed on at least a portion of one surface of the glass substrate. The coating has a thickness in a range from about 70 angstroms to about 120 angstroms. The coating consists, on a mixed metal oxide weight basis, of about 60 to 70% cobalt, 12 to 18% chromium, and 16 to 24% iron. A protective layer is placed over the coating.

Coated glass article

A method of applying a metallic oxide coating to a moving ribbon of glass is disclosed for four thicknesses of glass, namely, 7/32; 3/16; 5/32 and 1/8 inch. In each of these methods, first and second spray zones are established at opposite edges of the moving ribbon. The spray zones are moved in a simultaneous manner at the same speed from one edge to the other edge whereby the spray zones pass each other at the center line of the moving ribbon. When each of the spray zones reach the opposite edge of the moving ribbon, their direction of travel is reversed so that they once again pass one another at the center line of the moving ribbon. The first and second spray zones are spaced a slight distance from one another in the direction of movement of the moving ribbon. The moving spray zones are cycled back and forth in the aforedescribed manner continuously as the ribbon of material is moved thereunder so that a coating is applied to the moving ribbon. This method is used for applying a metal oxide coating to a moving ribbon of glass which is emerging from a float glass chamber.
