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 the populace. Restaurant owners found guilty of profiteering were slowly roasted on spits, and greedy bakers were baked in their own ovens. A physician, Dr C.J. Wills, traveling through Persia in 1866–81 noted that shortly before his (Wills') arrival, a "priest" had been burned alive. Wills wrote: The previous cases concern primarily death by burning through contact with open fire or burning material; a slightly different principle is to enclose an individual within, or attach him to, a metal contraption which is subsequently heated. In the following, some reports of such incidents, or anecdotes about such are included. Perhaps
