Bunsen burner flame. Close-up footage of a lit bunsen burner burning with a blue flame. The colour of the flame indicates how much oxygen is being mixed with the fuel. A blue flame indicates a high oxygen content, while a low oxygen content would result in a yellow flame. The fuel being burnt is natural gas. Bunsen burners are used in laboratories to heat chemical reactions and to carry out flame tests. | |
