It's interesting that, just as now in the 21st century glassblowers want to buy cullet, no latter how far it's got to be transported, so did glassmakers in Roman empire times. Most glass shops bought color and cullet from only 2-3 sources in the Levant and Egypt. The vessel makers rarely made their own glass.
The cullet was mostly melted close to good glass sands in large tanks. Very large tanks. The furnaces found at Bet Eli'ezer near Haifa in modern day Israel for instance, melted 8-10 tonne slabs of glass in situ and then the furnace was knocked down and the glass broken up into chunks which were shipped all over the Mediterranean.
