Kerosene is obtained by distilling crude petroleum which consists of a variety of inflammable liquids. The more volatile it is, the more brilliant the light. Kerosene which can be heated to 140° F. without yielding a vapor, will not take fire even if the container is broken and oil spilled.

The following rules for operating a kerosene stove should be observed: Select the best burners possible; do not blow directly down on the flame but blow across it; wash burners occasionally in a little washing-soda and if wicks are kept clean, smoke may be avoided; do not leave the burners with the flame turned down; change the wicks when they become clogged with impurities; do not fill the kerosene lamp or stove near a fire or burning lamp; burners should allow air to gain access to the wicks to create a current to carry off products; air holes and tubes should be free from dust and dirt; containers should be kept nearly full but if too full the oil expands with the heat and oozes out.
