  • System and method for texturing glass
    Patent number: 8815380
    Abstract: A method for texturing an alkali alumina silicate glass substrate includes cleaning the glass substrate with at least one surfactant and etching the glass substrate using a caustic solution. The percentage of caustic solution is provided by controlling a fluid flow and temperature to control the depth of the etching. The method also includes acid cleaning the etched glass substrate to remove glass residuals and surfactants and chemically strengthening the etched and cleaned substrate.
