I play for the scenario paintball team Pub Crawling
and with a name like that we know our way around a pint or two.
There was some interest about a writeup on etching glasses with a sandblaster from this thread here: http://www.homebrewtalk.com/f51/diy-...lasses-345017/
So here is a very quick and easy overview of how I etch glasses. This is different than using a chemical etching compound in that it goes much deeper into the glass, you can see and feel the difference in depth with sandblasting.
