Vycor is the brand name of Corning's high-silica, high-temperature glass. It provides very high thermal shock resistance. Vycor is approximately 96% silica and 4% boron trioxide, but unlike pure fused silica, it can be readily manufactured in a variety of shapes. [citation needed] Vycor can be subject to prolonged usage at 900 °C. [1]

Ultra low expansion glass has an coefficient of thermal expansion of about 10 −8 /K at 5–35 °C. [2] It has a thermal conductivity of 1.31 W/(m·°C), thermal diffusion of 0.0079 cm 2 /s, a mean specific heat of 767 J/(kg·°C), a strain point of 890 °C [1634 °F], and an estimated softening point of 1490 °C [2714 °F], an annealing point ...
Guitar slide made of borosilicate glass. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
Tubes made from expansion-resistant glasses, mostly borosilicate glass or fused quartz, can withstand high temperatures up to several hundred degrees Celsius. Chemistry tubes are available in a multitude of lengths and widths, typically from 10 to 20 mm wide and 50 to 200 mm long. [ 1 ]
