Production. Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately 2,200 °C (3,990 °F). This is an endothermic reaction requiring 110 kilocalories (460 kJ) per mole and high temperatures to drive off the carbon monoxide. This method has not changed since its invention in 1892: CaO + 3 C → CaC 2 + CO

Carbide lamps, or acetylene gas lamps, are simple lamps that produce and burn acetylene (C 2 H 2 ) which is created by the reaction of calcium carbide (CaC 2 ) with water (H 2 O). It was prepared by the hydrolysis of calcium carbide, a reaction discovered by Friedrich Wöhler in 1862 and still familiar to students: Arc furnaces were also used to prepare calcium carbide for use in carbide lamps.

Reducible oxides in the slag, primarily FeO and MnO, react with the calcium carbide to produce iron, manganese, gas and lime (CaO), as shown in the equations below. The other components of the NuFlux product then help to dissolve the CaO and facilitate the release of the CO which burns to CO2 as it contacts the air above the slag.
