Abstract
A method for polishing a glass workpiece is provided that includes contacting the glass workpiece having an initial Ra with an abrasive article comprising a three-dimensional abrasive coating bonded to a backing, applying a liquid at an interface between the glass workpiece and the abrasive article; moving the glass workpiece and the abrasive article relative to one another; and reducing the initial Ra to a final Ra. The abrasive articles are capable of rapid removal of glass stock from a glass test blank and reducing the surface finish using an RPP test procedure.
