Heating and Stoppering the Flask
The spherical bottom takes heat evenly, which is why round bottom flasks are used for boiling liquids over a burner and gauze or in a heating bath. It cannot stand on its own, so hold it in a clamp by the neck or rest it in a cork ring. The wall thickness is controlled to balance thermal expansion against mechanical strength for better resistance to thermal shock, and the flask can be autoclaved.
