As detailed by The Crucible in the article “What is Metal Casting?”, the art and science of metal casting has been practiced for over 7,000 years, evolving from ancient craftsmanship to a cornerstone of modern manufacturing. The process involves pouring molten metal into a mold, cooling it, and finishing the hardened object—a method that continues to be used for everything from jewelry to industrial engine blocks.
The earliest known cast object—a copper frog dating back to 3200 BCE—was discovered in present-day Iraq. Since then, civilizations around the globe have leveraged casting to produce weapons, tools, coins, and artwork. The Bronze Age saw a surge in casting thanks to the strength and workability of bronze. Notable contributions came from China’s Shang Dynasty with the first use of single-use sand molds, India’s early coinage with silver and copper, and iron casting innovations from the Zhou Dynasty.
