Young Brunette Girl Shows Off At The Kitchen Stove

In Europe, prior to the 18th century, people cooked over open fires fueled by wood, which were first on the floor or on low masonry constructions. In the Middle Ages, waist-high brick-and-mortar hearths and the first chimneys appeared, so that cooks no longer had to kneel or sit to tend to foods on the fire. The fire was built on top of the construction; the cooking done mainly in cauldrons hung above the fire or placed on trivets. The heat was regulated by placing the cauldron higher or lower above the fire.
Open fire has three major disadvantages that prompted inventors even in the 16th century to devise improvements: it is dangerous, it produces much smoke, and the heat efficiency is poor. Attempts were made to enclose the fire to make better use of the heat that it generated and thus reduce the wood consumption. A first step was the fire chamber: the fire was enclosed on three sides by brick-and-mortar walls and covered by an iron plate. This technique also caused a change in the kitchenware used for cooking, for it required flat-bottomed pots instead of cauldrons. Only in 1735 did the first design that completely enclosed the fire appear: the Castrol stove of the French architect François de Cuvilliés was a masonry construction with several fireholes covered by perforated iron plates. It is also known as a stew stove. Near the end of the 18th century, the design was refined by hanging the pots in holes through the top iron plate, thus improving heat efficiency even more.
