The term oxy-acetylene refers to the flame. The gases used for sustaining combustion in this case are acetylene which is fuel gas and air which has presence of oxygen which acts as oxidant to support the flame ignition. Majority of elements can be studied with acetylene and air oxygen is not used due to high flame velocity of acetylene-oxygen flame which can result in flashback and explosive bang in the burner other common combination is acetylene and nitrous this case the oxidant required to support combustion is nitrous oxide , This flame results in higher temperature than air -acetylene flame. Such temperatures are necessary to decompose metals forming stable oxides(refractory elements)
Some reference management software include support for automatic embedding and (re)formatting of references in word processing programs.
