Candles can burn because paraffin itself can burn, but the ignition point is relatively low. Therefore, a lot of heat should be provided to melt the wax before it burns. After adding the wick, you only need to melt a small amount of paraffin on the wick to light it. Then the heat generated after combustion continuously melts the surrounding paraffin, so that the combustion can continue. Candle is a kind of lighting product that can burn continuously after lighting, and it is composed of wax or other dyes and wick.
