Coppersmith extensive degree it must be annealed. This process involves heating the metal and then rapidly cooling it in water. The cooling stage is known as quenching. By heating the copper, the molecules in the metal are relaxed, and thus able to align themselves in a more uniform fashion. This allows for easier shaping of the metal. In order to keep this uniformity within the metal, it is cooled instantly. This prevents the molecules from moving around and causing tension in the structure of the metal. Unlike ferrous metals—which must be cooled slowly to anneal—copper can be cooled slowly in air
Death by burning of death resulting from exposure to extreme heat are known. For example, pouring substances such as molten metal onto a person (or down their throat or into their ears), as well as enclosing persons within, or attaching them to, metal contraptions subsequently heated. Immersion in a heated liquid as a form of execution is considered distinct from death by burning, and classified as death by boiling. The 18th century BC law code promulgated by Babylonian king Hammurabi specifies several crimes in which death by burning was thought appropriate. Looters of houses on fire could be cast into the flames, and
