Abstract
A method of polishing and cleaning a glass surface with a single abrasive article. The abrasive article includes ceria abrasive particles dispersed in binder, the abrasive article having a textured, three-dimensional abrasive coating. The method includes contacting the glass surface with the abrasive article at a desired pressure and in the presence of water, and moving the abrasive article and glass in relation to each other under pressure. The water is believed to mediate a chemical reaction involving the ceria and the glass, thereby leaving a haze on the glass surface. With continued motion of the abrasive article in relation to the glass workpiece, without the addition of additional water, the haze is removed.
