Most places only take beverage glass, and not windows.
Those that do generally want it cleaned too, and sorted by color. Green, brown, clear etc...
the ones that would take dirty glass tended to pay a lot less for it.
the average rate tends to be a penny or two a pound for it.
id recommend going through the phone book or a google search or something like that. for example glass recycling jacksonville florida, see how many hits you get.... yellowpages dot com is also a good place to global search for recycling sites.
