Glass has a very low coefficient of thermal expansion. This is the reason why thermometer bulb or for a matter of fact entire thermometer is made up of glass. Due to low coefficient of thermal expansion, when the thermometer undergoes a large temperature change it will have minimal change in dimensions.
