THERMAL PROPERTIES In general, the “Strain point” should be regarded as the maximum safe operating temperature of borosilicate glassware. When heated above 500º C the glass may acquire permanent stresses on cooling. All borosilicate labware is annealed in modern Lehr ovens under strictly controlled conditions to ensure minimal residual stress in the products. The typical thermal properties of borosilicate glassware are given below:
