In the first half of the 19th century, intensive attempts were made to obtain more efficient and cheaper fuel than the various types of oil and their mixtures used to date.
To this end, research was conducted on crude oil, from which kerosene was obtained by distillation. ...
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.
