A colorless, flammable
gas, with a garlic-like odor. Its combustion in pure oxygen
produces the highest achievable flame temperature, over 3300°C,
releasing 11,800 J/g, allowing it to be used in welding,
cutting, brazing, and soldering metals. The oxy-acetylene torch
can be used to repair ships underwater, to construct bridges,
pipelines, dams, tunnels, buildings and to reinforce concrete.
