    A. Introduction   90 minutes   The History of Toaster Ovens
        Panimula                      Believe it or not, the ancient toaster oven was nothing more than a curved
                                   stone that relied on fire to work. It was discovered by the Romans as a way to
                                   preserve bread. In fact, it is difficult to outline the history of the toaster oven
                                   without talking about the history of bread. The latter, as we know it, has its
                                   origins in ancient Egypt about 8,000 BC. The Romans learned bread making and
                                   baking from the Egyptians.
                                   Who Invented the Early Ovens
                                   How did the Romans discover the early earthen ovens?
                                       Basically, they realized that dough left sitting
                                   close to the fireplace would rise. Moreover, they
                                   observed that bread would maintain its risen
                                   shape when exposed to air and heat. With time,
                                   they invented simple devices that enabled them
                                   to toast bread over fire. These were in form
                                   of hand-held wireframes and sticks like those
                                   used to toast marshmallows today.
                                       Have you ever looked at the toaster oven in your kitchen and wondered about
                                   its origin? Well, this appliance has become one of the integral tools in any
                                   home, and has evolved from a simple, single unit to an appliance serving various
                                   purposes. This appliance comes in various brands, each brand with its own
                                   specification. So, when did the toaster come into being and what changes has
                                   it gone through to give you the final product?
                                      200 years ago, man could toast
                                   bread by placing it between a pair of
                                   metal frames and holding the ensemble
                                   over a fire to heat it. The metal
                                   frames were consequently held in
                                   place by a stick or a long knife.
                                   Something had to be done.
                                   1910 – The Birth of the Idea
                                      The idea of the toaster oven came to front in the mid-nineteenth century
                                   and borrowed on the idea of the electric toaster. Building on this idea, William
                                   Hadaway built the first oven toaster in 1910 for his client, the Westinghouse
                                   Corporation. The idea was accidental, having been a way to create a stove
                                   from materials remaining over from electric stove manufacture.
                                   1919 – Time for the Pop Up
                                      The model of the toaster common today is called the pop-up toaster. This idea
                                   came into being in 1919. Before this, users had to turn the bread manually during
                                   the roasting process. Charles Strite came up with the idea of the bread
                                   popping up, a task implemented together with Waters Genter Company. The first
                                   model to make use of the pop-up technology was launched on the market in 1926.
                                   1936 – 1961: More Innovative Changes
                                      In 1936, a company came up with a toaster complete with a pneumatic
                                   shock absorber, which made sure the toasting operation was quiter and smoother.
                                   The first toaster to work with the “self-lowering” technology saw the light of day in
                                   1950. This model came complete with an improved timer to reduce on power
                                   surges.

                           1971 – 1978: Different Finishes Are Introduced
                               Initially, these appliances came in woodgrain and painted finishes, which
                           had become more and more popular. 1971 saw the introduction of decorative
                           finishes that made the toaster oven more fashion oriented. However, chrome still
                           remained the most popular finish, but some ovens came with decorative front
                           panels.
                           1978 saw the introduction of the double-slice toaster.
                             This toaster went on to become one of America’s most popular toaster models.
                           1985 – 1996: Accelerated Changes in Design
                             To take care of limited space, the first under-cabinet toaster came into being in
                           1985. Shortly after in 1990, the first cool touch toaster came onto the fore.
                           Current
                              Decades later, you now buy ovens that have advanced features and better
                           performance. Toasters today use horizontal filaments unlike the vertical ones. You
                           can as well reheat your bread without burning it. You have a chance to choose
                           from a host of brands, each with different functions. The toaster today has larger
                           slots to allow you to toast all manner of foods. A number of settings give you the
                           ability to define the temperature. Some toasters even provide 4 slots to toast
                           more slices of bread.

                                 Oven Toaster is a small, countertop oven that is used to prepare a wide
                           variety of foods efficiently and easily. Often used as an alternative to heating a
                           larger kitchen oven, the Toaster Oven reheats, bakes, broils, toasts, browns, and
                           defrosts small amounts of foods.
                               Typically, the Toaster Oven is manufactured with fast-acting heating elements
                           that are managed with easy to use controls. The control panel may be built
                           with mechanical settings or digital settings. In addition, the heating elements may
                           be conventional that are similar to a kitchen oven or convection to provide
                           more functions within the oven. Standard-sized Toaster Ovens range from 15 to
                           22 inches wide and from 8 to 12 inches in height.
                                Another version of a Toaster Oven is referred to as a Salamander Oven which
                           is basically an oven used for browning foods. However, this small broiler oven is
                           also used to quickly brown, glaze, cook, broil, or toast various foods. The
                           Salamander can provide a nicely browned crust to a crème brûlée, an au gratin
                           dish or a toasted bread. Manufactured in both small or larger sizes, the
                           Salamander oven units that are larger are designed to be mounted above a
                           cooking range or on a wall. The smaller Salamander Ovens are manufactured
                           similar to a Toaster Oven, so they can be placed on a counter.
