Understand what FLASHPONT IS. Flashpoint is the lowest temperature at which a liquid fuel will give off vapors in order to ignite. Liquid fuels themselves don't burn, it's only when their flammable vapors mix with oxygen will they burn. While gasoline has a VERY low flashpoint making it ignitable at just about any ambient temperature, mineral spirits are nothing to take lightly. Mineral spirits have a flashpoint of around 100-110 F. If the liquid is heated to this temperature, if gives off vapors and is just as ignitable as gasoline. This occurs until ALL of the liquid is evaporated. While it needs a source of ignition, you would be suprised that even a static electric spark could be enough to ignite the vapors. In industry, when mixing such chemicals, they are often blanketed with nitrogen. Lack of oxygen in the environment makes it impossible to ignite...........
BE CAREFUL
