The three diagrams illustrate the process of improving cooking device. It is a clear and coherent representation.
Overall, it is evident that there are three different stages in the process, from the initial simple fire to complex equipment; which is used for cooking.
At the first stage, there was simple cooking equipment: pot, which was balanced by three stones over a fire of twigs and grass. In the second diagram, same material were used with a shield which was made of clay, around the fire. It was used to prevent the loss of heat, and protect the fire from wind.
At the final stage, there were many tools which was used for cooking. Fire was enclosed by metal base; which was used to control the heat. There is a door at the front where air can enter and ash can be removed. Charcoal used as fuel. There are also metal support, with the help of this pot can balanced on the stove, and a handle for easy transportation.
