Flammable & Combustible Liquids

A material's autoignition or ignition temperature is the temperature at which a material self-ignites without any obvious sources of ignition, such as a spark or flame. Most common flammable and combustible liquids have autoignition temperatures in the range of 300°C (572°F) to 550°C (1022°F).

Does Room Temperature Affect Wood Staining? | Hunker

Worried that the reading on your thermostat might interfere with your wood staining project? Most indoor rooms stay within the safe temperature range, but extremes on the hot or cold end can affect how the stain responds. Cold temperatures can slow the process. If your room feels more like a sauna than an igloo, the warm temps can speed up the process too much.
