I use a good glass cutter, held firm on a solid spacer on the bench, and rotate the bottle against the cutter to score a stress concentration/cut line all the way around - important that you do not go over the line more than the initial score. Holding the bottle over the sink, bottom just above the drain I slowly pour boiling water on the stress line, rotating the bottle, one of two times around, then turn on a small stream of cold water and follow the line again. Repeat, and it will suddenly pop off into the sink. I sometimes start by pouring about 1/2" of hot water into the bottle, swishing it around gently, and then pour it out before the cold water part. Generally a 90+ success rate.
