Acetylene was discovered in 1836 by Edmund Davy who identified it as a "new carburet of hydrogen." It was rediscovered in 1860 by French chemist Marcellin Berthelot, who coined the name "acetylene." The Nobel Laureate Gustaf Dalén was blinded by an acetylene explosion.
The principal raw materials for acetylene manufacture are calcium carbonate (limestone) and coal.

As indicated earlier, the Bible does not fix the age of the earth, contrary to the claims of Answers in Genesis.
Historically, their claim comes from the work of James Ussher, Bishop in the Church of Ireland, from 1625 to 1656.
Sabretoothed Carnivores and the Killing of Large Prey. The carbon-carbon triple bond leaves the carbon atoms with two sp hybrid orbitals for sigma bonding, placing all four atoms in the same straight line, with CCH bond angles of 180°.Above 400 °C(673 K) (which is quite low for a hydrocarbon), the pyrolysis of acetylene will start.Acetylene can also be manufactured by the partial combustion of methane with oxygen, or by the cracking of hydrocarbons.Berthelot was able to prepare acetylene from methyl alcohol, ethyl alcohol, ethylene, or ether, when he passed any one of these as a gas or vapor through a red-hot tube.
