Hi, there. I worked in the tractor cab factory we cut flat laminated glass for the windows and windshield. We would score both sides of the glass with a glass cutter than pour lighter fluid in the score line on one side of the glass. You have to Set the lighter fluid on fire so it would soften the inner laminate and then snap the glass like you would do on house window glass. I practiced a lot on small pieces that were cut offs until I could do a good job.
