How does a Lighter make fire?

However, have you ever wondered how lighters produce a flame so perfectly ovate, as if it materializes from a candle, out of thin air? The modern lighter store butane. It initially stored naphtha, until we realized that butane produces a more controlled flame and exudes the least amount of unpleasant odor. Butane in a lighter is pressurized and stored, which causes it to exist as a liquid. When depressurized, the liquid will immediately vaporize to form gaseous butane. The gaseous butane, being flammable, will catch fire even when incited by the slightest of sparks. The metallic wheel on the lighter, when pushed down by one’s thumb, will rub against the ferrocerium to produce a scorching spark. Simultaneously, a valve opens, from which the butane is released, which is vaporized (depressurized) as soon as it exits the container. The spark is produced just above the valve, which then simply ignites the plume of gas. The result is an ovate, tranquil flame. When you “click” a lighter, the piezoelectric material deforms and bears a current. Above the valve through which the butane exits, two separated wires produce between them what is called a voltaic arc, an electric discharge or plasma, like the thorns of current surrounding Thor. This discharge, like a spark, will ignite the depressurized gas and produce a candle-like flame.
