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?

Annealed (ordinary) glass breaks at a temerature-DIFFERENCE of approx. 30-40 degree Celsius.
In this case a difference in temperature between top and bottom of the glass table top.
Thermally tempered / toughened glass can withstand a temperature-difference of approx. 200 degree Celsius.
