Glass breakage in fire.

I am currently investigating a fire which involved a glass table top. There was a candle and some other combustible items on the table. At what temperature would the glass top fail? I am thinking the combustible items ignited and the table top failed allowing ignition of the wooden table beneath the glass. Any info?

Excessive solar heating

I have a large modern home in Toronto, Canada. The back of my house faces south and is 90 % windows. ( 10' by 10' windows). On sunny days the solar heat transfer is excessive. Current windows are low e. I have installed 3M film, but not much help. In fact, now that solar film is installed, I am experincing window cracking. Is there an engineered window system that will block most of the solar energy ? I prefer to stay away from mirrowed windows.

Windshield spontaneous crack

My windshield one cold day out of the blue cracked. From the bottom up about 5 inches and then across the window. I claimed it was defective glass that the dealer should replace under warranty. But they used this "ball point pen" test. They run a ball point pen along the crack and if they feel any chips then they say that the window was damaged by an object hitting the window.

Very fine windscreen scratches

I have accidently put very fine scratch/swirlmarks on my car windscreen by using a plastic scourer pad. They are not detectable with my fingernail and are only visible when bright light shines on the screen, but can distract the eye from the road ahead. Is there a cure to this problem as a new screen is expensive! Please help! Cheers
