A boiling tube is a special variety of test tube that is made specifically for boiling samples. Most boiling tubes are made of borosilicate glass. These thick-walled tubes are usually about 50% larger than average test tubes. The larger diameter allows samples to boil with less chance of bubbling over. The walls of a boiling tube are intended to be immersed in a burner flame.
