did u know . . .. History of Ovens . . .
The first written historical record of an oven being built, refers to an oven built in 1490, in Alsace, France. This oven was made entirely of brick and tile, including the flue.
Around 1728, cast iron ovens really began to be made in quantity. These first ovens of German design were called Five-plate or Jamb stoves.
Around 1800, Count Rumford invented a working iron kitchen stove called the Rumford stove that was designed for very large working kitchens. The Rumford had one fire source that could heat several cooking pots, the heating level for each pot could be regulated individually. Cast iron stoves continued to evolve.
Jordan Mott invented the first practical coal oven in 1833. Mott's oven was called the baseburner. The oven had ventilation to burn the coal efficiently.
British inventor, James Sharp patented a gas oven in 1826.
It was not until the late 1920's and early 1930's that electric ovens began to compete with gas ovens, however, electric ovens were available as early as the 1890's.
Some historians credit, Canadian Thomas Ahearn with inventing the first electric oven in 1882.
The microwave oven was a by-product of another technology. It was during a radar-related research project around 1946 that Dr. Percy Spencer, an engineer with the Raytheon Corporation, noticed something very unusual.
