WebBorosilicate glass has a much higher proportion of silicon dioxide in comparison to regular soda lime glass (80% vs. 69%), which makes it even less susceptible to fractures. In terms of temperature, the maximum thermal shock range (the difference in temperatures it can withstand) of borosilicate glass is 170°C, which is about 340° Fahrenheit. WebThe glass fully meets the requirements set down by these standards. Pyrex 7740 and Duran 8330 belong to this same class. Soda-lime Glass Thermal expansion 0–300°C = 93.5 × 10−7°C Strain point 473°C Annealing point 514°C Softening point 696°C Working point 1005°C Fused Silica Thermal expansion 0–300°C = 5.0 × 10−7°C
