gas from iron ore used to light

Iron ore - Wikipedia. 9/11/2002 Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces.Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel.

Liquid fuel irons: A 19th century invention that is still ...

Jul 30, 2017 · First to appear were the gas irons in the second half of the 19 th century, after gas was introduced in homes. Using a pipe, the iron would be connected to the house’s gas line or to a canister. The gas flowed to a burner, which when lit would heat the iron. The pipe was designed so it would stay out of the way of the user.
