Re: [Phys-l] glass

  The trick to using a razor blade is to keep the angle between the glass and the blade rather small. I have scraped miles of labels from glass using this technique without ever a scratch. Slide the blade sideways a bit while pushing it. Most glass is pretty hard even compared to a blade.
