Resistance to Thermal Shock
Resistance to thermal shock is not an exact, by defined physical quantity (for more details see ISO 718); it depends on the measuring method, the shape, the wall thickness and the surface and end properties of the glass object in question. Rapid temperature changes cause high temporary stress in the glass, meaning that rapid cooling processes are very dangerous, since in this case a thin outer layer of the glass is placed under tensile stress over the still hot inner core. Glass is much more susceptible to tensile stress than to compressive stress.
The following graph shows the resistance to thermal shock of the tubes Duran, Durobax, Fiolax Clear, Fiolax Amber, Illax and AR-Glas:
