How is glass recycled into new things?

You toss an empty jam jar into the recycling bin and it clinks against the others. Where does it go next? Does someone melt it down and blow it into a new jar, or does something weirder happen first?
The jar rides in a truck to a recycling plant, where it tumbles onto a conveyor belt with hundreds of other glass containers — green wine bottles, brown medicine bottles, clear soda bottles, all jumbled together. First job: get rid of the stuff that isn't glass.
