The diagram illustrates the process of improving cooking utensils. It is indicated that there are three distinct stages from the process, from the initially simple to eventually complicated equipment.

At the first stage in the development of cooking equipment, there is only a simple cooking pot balanced on many stones over many twigs and grass. Moving to the second image, it shows how the equipment has improved by building a shield made of clay around the stone to protect the fire. There is also a hole that is used to put the sticks, as well as, twigs inside the shield.

At the final stage of the diagram, the equipment is more complex. The clay shied is replaced with a metal one combined with a door in order for the entry of air and the flow out of ash. Above the shield, there is an equipment used to support port with handles, as well as clay lining surrounds the utensils. In the bottom, there is a grate for putting charcoal inside.

In fact, cooking equipment has developed significantly to a more complicated level.

The given diagram illustrates the various stages in the manufacturing of the cooking utensils.

Overall, it is evident from the diagram that utensils were made in three stages from a simple pot to complex equipment.

Looking more deeply into the diagram, the main products were heated in a simple pot which then transforms into a beautifully placed clay shield. The clay shield is not covered in order to allow heat loss and to avoid excessive temperature.

Moving forward, the last stage of manufacturing took place in a very sophisticated and complex instrument. It is covered with a clay lining and has a handle to support its' handling. Also, there is a door in the metal equipment which allows the workers to remove the ash and air from the equipment. In the middle of the instrument, a grate is present to accommodate the charcoal. Similarly, there are three handles to support a pot.
