However, Łukasiewicz did not stop his distillation attempts and finally found the proper fraction, collected at the temperature of 250-350 °C (482 - 662 °F), devoid of light petrols and heavy hydrocarbons.
The resulting kerosene burned very well, so Łukasiewicz decided to use it for lighting rooms.
