From Wikipedia
A toaster is a small electric appliance that uses radiant heat to cook sliced bread into toast. When cooked the bread browns due to the maillard reaction. It typically consists of one or more slots into which bread is inserted, lowered, and cooked using heating elements, often made of nichrome wire, to generate heat and toast the bread.
