Transcript of Evolution of Stoves


The Open Fire Stove Above is the world's first stove, called the open fire stove. People would cook
their food by holding it directly over the blaze. Open fire stoves were very
dangerous because there was nothing protecting you from the fire. One wrong
move or stumble and you could burn yourself. The open fire stove also had
very poor heat efficiency and did not cook food evenly. Hearth After the open fire stove came the hearth or fireplace. The hearth was a step up
from the open fire stove because it was covered on the top, bottom and three sides.
This reduced the chance of injury. To cook, people would hang a cauldron onto a
rod that hung over the fire. Heat was regulated by making the distance between
the fire and the cauldron larger and smaller. However, although the hearth was a step
up from open fire, it was still dangerous and produced a lot of smoke. Inventors
were busily trying to come up with ideas to improve the stove. Castrol Stove Success!!! In 1735, the first stove where the fire was completely enclosed,
the Castrol Stove, was invented! The Castrol stove, also known as a stew
stove, was a masonary construction in which the fire was closed in on all
sides. The top of the stove was an iron plate with holes on it. To cook, you
placed your pot or pan on top of the plate and the heat came through the
holes. The Castrol stove improved safety and heat efficiency even more, and
was also more environmentally friendly because the heat stayed inside and
you didn't have to use as much wood to keep it going.
Iron Stove Next in the evolution of stoves is the iron stove! The iron
stove was the best one yet and had many things the others
before it hadn't had. The first was a labyrinth path for hot
exhaust gases to escape through. It was also possible to
regulate heat for each hole on the iron stove, and the stoves
often came with installations for heating water. Another
feature added to the iron stove was that rings were placed
over the holes where the heat came through. Then you could
just place your pots or pans over the rings. The iron stove
was by far the safest and most efficient stove yet. Gas Stove Sometime after the iron Stove was invented came the gas Stove.
The gas stove used propane or natural gas instead of wood
making the stove even more environmentally friendly and safe. Gas
stoves became very popular because they were so heat efficient
and easy to use. The gas stove was definitely the most efficient stove
yet. Electric Stove After the gas stove came an even better invention and the one we are
currently using today. The electric stove used electricity instead of gas and
fire, making it once again safer and more efficient that any other stove in
history. The electric stove had a slow start because of the unstable
technology but eventually became just as popular as the gas stove. With the new electric stove came new glass and ceramic cooktops and electric heating coils, making the stove even better. Even today we are still coming up with ways to make the stove more efficient, safe, and better for our environment. Today though, we are starting to see more households
returning to the use of gas stoves because of cost efficiency. The Evolution of Stoves Resources Images:
