A tandoor is a large vase-shaped oven, usually made of clay. Since antiquity, tandoors have been used to bake unleavened flatbreads, such as roti and naan, as well as to roast meat. The tandoor is predominantly used in Western Asian, Central Asian, South Asian, and Horn of African cuisines.

An oven is a tool which is used to expose materials to a hot environment. Ovens contain a hollow chamber and provide a means of heating the chamber in a controlled way. In use since antiquity, they have been used to accomplish a wide variety of tasks requiring controlled heating. Because they are used for a variety of purposes, there are many different types of ovens. These types differ depending on their intended purpose and based upon how they generate heat.
