Borosilicate glass has a low thermal expansion coefficient, allowing it to withstand high temperature gradients and sudden temperature changes. However, any scratches on the surface can reduce its thermal resistance. The recommended maximum safe operating temperature is around 500°C, known as the 'Strain Point.' Heating the glass above this temperature may cause permanent stresses upon cooling.
