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.
Most types of steel melt between 1370°C (2500°F) and 1500°C (2732°F).
The melting temperature depends on its composition. In general, high-alloyed steels containing more alloying elements have higher melting points than low-alloyed steels.
China is the world's largest producer of steel. The country accounts for 57% of the world's production.
The European Union is the second largest producer and India is the third largest producer. Other major global steel producers are: Japan, USA, Russia, South Korea and Turkey.
On 30th August 2016, the Airspace Industry Corporation of China signed an agreement with Antonov Corporation to complete the second machine and start production of more, with upgraded avionics and a different propulsion system.
The first attempt to use kerosene for lighting ended almost tragically. Łukasiewicz used an oil lamp that was not adapted to the new fuel, and the lamp exploded.
Miraculously the apothecary avoided severe burns. Łukasiewicz turned to a Lviv tinsmith Adam Bratkow ...
