Research on the uses of fire in vernacular houses in the Eurasian Continent

How fire was used in vernacular houses before modernization was a reflection of life in dwellings adapted to the natural environment. In vernacular houses fire has been used as a heat source for heating and cooking, and its flames for lighting. The author carried out literature research and a field survey on the use of fire in vernacular houses in Eurasia. Fire is used for cooking in hot areas and in temperate areas in winter, and in cold areas for heating, cooking, and lighting. The paper shows that the change from using fire for cooking to using fire for cooking and heating in vernacular houses occurs at around Lat. 40 degrees N. on the west of Eurasia and around Lat. 35 degrees N. on the east of Eurasia.
