I've always wondered how you do that. Do you place the bottle directly in the coals, hold it on a stick or what?

Well, the stick would certainly catch fire at the temps required to melt glass...you city types! ;-)

The glass cracks more often than not when cooling as there is no moderation of temps. But sometimes you can get lucky and lay a beer or wine bottle on a bed of hot flat coals and get something interesting.
