A Toaster is a small electric appliances that uses radiant heat to brown sliced bread into toast, the color caused from the Maillard reaction. Toaster ovens are small electric ovens that can be used for a wide variety of purposes, including baking or toasting.In a pop-up or automatic toaster, a single vertical piece of bread is dropped into a slot on the top of the toaster. A lever on the side of the toaster is pressed down, lowering the bread into the toaster and activating the heating elements. The length of the toasting cycle (and therefore the degree of toasting) is adjustable via a lever, knob, or series of pushbuttons, and when an internal device determines that the toasting cycle is complete, the toaster turns off and the toast pops up out of the slots.
