Candle radiation

WebHow Candles Burn. All waxes are essentially hydrocarbons, which means they are largely composed of hydrogen (H) and carbon (C) atoms. When you light a candle, the heat of the flame melts the wax near the wick. This liquid wax is then drawn up the wick by capillary action. The heat of the flame vaporizes the liquid wax (turns it into a hot gas ...
