Abstract:
An abrasive article for polishing glass and ceramic surfaces comprised of a combination of abrasive particles and inorganic glass polishing aid dispersed throughout a three-dimensional nonwoven fibrous web of organic material, and adhered therein by a resinous binder. The article is capable of refining a ground glass or ceramic surface to a highly polished surface faster than abrasive articles known in the art.
