Cold blastWikipedia
Cold blast in ironmaking refers to a furnace where air is not preheated before being blown into the furnace.This represents the earliest stage in the development of ironmaking. Until the 1820s the use of cold air was thought to be preferable to hot air for the production of high-quality iron this effect was due to the reduced moisture in cool winter air.

Iron FurnacesHiker s Notebook
The iron blast furnace is an enhancement to the bloomery furnace in the application of higher levels of heating to create molten iron. The first blast furnaces were in use in China by the first century BCE (and possibly earlier) and there is some credence to the hypothesis that the Chinese skipped the bloomery process altogether. In China backyard furnaces () were small blast furnaces used by the people of China during the Great Leap Forward (1958–62). These were constructed in the backyards of the communes to further the Great Leap Forward s ideology of the rapid industrialization of China.. People used every type of fuel they could obtain to power these furnaces from coal to the wood of coffins.
