"Irons that are heated by natural gas, denatured alcohol, kerosene and gasoline are categorized as liquid fuel irons. The irons that were heated with these fuels could readily be ignited and the heat could be controlled. Since little or no smoke and soot was produced, liquid fuel irons represented a major improvement over charcoal irons." David Irons, Irons By Irons, page 108.
