Sandblast or etch.
Sandblasting is done with, well, a sandblaster (small) and rubber mats as masks. The grit bounces off the rubber but etches the glass. A series of mats can be used to etch to a different depths (like contours on a hiking map).
Etching is done with hydrofluoric acid. It is tricky stuff, but less so in paste form used stain-glass artists. Cover what you don't want etched with wax. Paint on the paste and leave it a varying amount of time depending on the effect you want. The result is "frosted" glass.

You coat the glass with paraffin wax; the stuff candles are made of. Then you draw your design on the wax with a needle. Then you immerse it in hydrofluoric acid, one of the few substances that reacts with glass. You store the acid in a polythene container, in anticipation of your next question. Hydrofluoric acid doesn't react with alkanes or alkenes. It's very nasty stuff. Take care.
