The diagrams illustrate the various stages in the evolution of cooking equipment, showcasing the changes from common materials to convenient and latest designs.
Overall, the changes are discussed in three main phases: A, B, and C. These phases rely on stone, clay, and metal respectively, as the constructive materials for the equipment. The presence of stone reveals the simplicity of the initial equipment and its progression into a complex and modern design.
Initially, Phase A features contain clay craft enhanced by stones, stick, and paper to lighting the fire.
Phase B demonstrates a significant improvement, with the clay shield protecting the fire from wind and water.
The major development occurs in Phase C, where the stove is constructed from metal, allowing for faster heat conduction. Additionally, the handle aids that prevent from heating.The clay lining and door ensure that ashes remain inside the appratuse and the heat is controlled.The top pot which holds charcoal, representing a modern and complex design.
