When was the oven created




















From roasting pits to cauldrons to earthen kiln-like structures, some form of oven has been around forever. Interestingly and perhaps appropriately, France was home to the first written historical record of an oven being built, constructed using bricks and tiles. Around , German-designed cast-iron ovens began being made in serious quantities. These were known as Five-plate or Jamb stoves. The enclosed nature of the oven was an innovation as it contained the smoke inside the oven, which had not been done before.

Towards the end of the s Benjamin Thompson aka Count Rumford invented an iron stove that allowed the user to adjust the temperature of the individual stovetops; a huge innovation at the time, and a step towards our modern stovetops.

Colonial America: Imagine trying to bake a cake without being able to precisely gauge or control the temperature.

It had a single fire source yet the temperature could be regulated individually for several pots at the same time, all while heating the room, too. Its biggest drawback was that it was too large for modest home kitchens. But it took another three decades for the first commercially produced gas stove, designed by Englishman James Sharp, to hit the market. The stoves became popular by the end of that century for being easier to regulate and requiring less upkeep than wood or coal stoves.

He experimented further with microwave radiation and realized that it could cook food more quickly than through the application of heat. Eight years later, the company produced its first commercial microwave oven; its Amana division released the first domestic version in
