Nanoscale Polishing of Window Glass

The surface of window glass is rough down to an order of about five microns. The micro pores of the surface of window glass are on the average this big. So when we polish windows using a cerium slurry with a similar particle size, we can only hope to attain this degree of roughness. Which is average. Five microns is five thousand nanometers. It is now common practise to polish glass flats used in optics down to a roughness of twenty nanometers. That is 250 times finer than what we are accustomed to. Since glass is water loving, (hydrophylic) the tighter the surface the more it will bead water. The rougher the surface the more it will hold onto water forming a film. So by super polishing glass on a nanoscale, we can create a natural rain repellant that will help to prevent the natural process of etching. In short, get rid of the craters and holes, and make it smooth.
