Why are test tubes made of glass?

Test tubes, intended for general chemical work are usually made of glass, for better resistance to heat and corrosive chemicals and longer life. Tubes made from expansion-resistant glasses, mostly borosilicate glass (or fused quartz) can withstand high temperatures, up to several hundred degrees Celsius.
