I have a small glass shop where I blow , cast, bend ,cut and drill glass. Windshield glass has a high COE (coefficient of expansion), probably about 120. This makes it easy to cut but subject to cracking due to the high expansion rate. What you want to avoid is temperature differential. Warm glass is easier to work with than cold glass. warm up the entire piece and use warm water. I like to submerge if possible. Also a couple of suction cups help with vibration. Your expert probably knows this I just thought I would throw it out there.
