Abstract

Materials have been of great interest to human beings since time immemorial. A few million years ago, it was found that rocks could be used to break things that were impossible to break with bare hands. Stones were the first tools and even today they are still in use in kitchens and laboratories to pound and grind, or as mortars and pestles. Around 5000–6000 years ago, it was accidentally discovered that when a rock containing copper was placed on a fire, molten copper could be collected. This discovery led to the reduction of metal ores to produce metals for the fabrication of items from ploughshares to swords. New materials with greater hardness and longer use than stone became available for making tools. Our growth and progress have paralleled the development of metals and metallurgy.
