When u light a candle or a wick in oil, what stops the oil or wax (flammable) from catching fire?

The wick is made to contain the flame


and the oil or wax would need much higher temperature


than created in the oil candle or wax candle.

It's not hot enough,Sariyu. A candle or oil lamp is a gas factory; capillary action draws the liquid up the wick where the heat from the burning gas vaporizes the liquid, and the heat from the burning gas causes the gas produced to ignite. Try this: blow out a burning candle somewhere where the air is perfectly still. You will see the gas condense to a white smoke rising from the wick. If you place a burning match close to, but not touching the wick , in the stream of white vapor, (condensing wax), it will relight the candle.When u light a candle or a wick in oil, what stops the oil or wax (flammable) from catching fire?
Flash point of oil or wax is too high to catch fire. At flash point vapours are enough to ignite at particular temprture.
