Layman's explanation:
Acetylene is an odorless and colorless gas that was discovered in England by E. Davy. This gas can be made from limestone and coal or from other petrochemical processes. The combustion of acetylene and pure oxygen produces the hottest flame temperature possible of 3300oC. As a result, it is an important fuel for welding and cutting metals. In addition, this chemical can be used as an anesthetic, however overexposure is hazardous. Nowadays acetylene is used for carburization (i.e. hardening) of steel. Research in the last ten years came to the conclusion, that acetylene is the best hydrocarbon available for this purpose.
