When calcium oxide is treated with water it forms calcium hydroxide, Ca(OH) 2, or slaked lime, which absorbs carbon dioxide from the air and gradually forms calcium carbonate, CaCO 3. Lime, heated by hydrogen burning in oxygen, burns with a brilliant white light, which can be focused into a narrow beam visible over great distances.

Copper - Wikipedia

Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals).This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposefully alloyed with another
