The chemical symbol for lead, Pb, originates from the Latin term “plumbum,” giving rise to the word “plumber” in contemporary language. Roman artisans handcrafted lead into sheets that could be fashioned into a multitude of items, including cookware, water pipes, and even coins, which played a significant role in the proliferation of currency. As architectural advancements led to taller and larger structures, the need for durable roofing materials became imperative, laying the groundwork for the widespread use of metals in construction.
