Compare with auto-ignition temperature. The temperature when vapor pressure of a substance becomes high enough to allow the air/vapor layer over the substance to be ignited. Ether and acetone have flash points below room temperature, which makes them very dangerous.

The lowest temperature at which the vapor of a combustible liquid can be made to ignite momentarily in air. This relates to both wax and fragrance oils. For wax it is the temperature that wax would have to reach before it combusts and catches fire. For fragrance oil it is the temperature the oil would have to be in order to catch fire when comin...
