Abstract
A method for patterning or texturing the surface of glass manufactured by the float process. The method comprises depositing particulate carbon onto the surface of a continuous ribbon of heat softened glass which is being drawn across a molten metal bath, the ribbon being cooled into a structurally integral sheet during this process. The deposited carbon attacks the surface of the glass to thereby produce a patterned or textured finish thereon.
Claims9
A method for texturing the surface of glass manufactured by the float process comprising:
- a. introducing molten glass at a controlled rate onto a molten metal bath to form a continuous ribbon of heat softened glass;
- b. drawing said ribbon across said bath while cooling said ribbon into a structurally integral sheet;
- c. depositing particulate carbon onto the surface of said ribbon while said ribbon is being drawn across said bath;
- and
- d. removing said integral sheet from said molten bath and introducing said sheet into an annealing lehr having an atmosphere containing sufficient oxygen to remove substantially all said carbon while said sheet is at a temperature greater than the ignition temperature of said carbon deposited on said sheet.
