How it all began: The invention and re-invention of glass in the ancient world
Beads and small vessels made of strongly coloured, frequently opaque, soda-lime-silica glass were made around the middle of the second millennium BCE in the Middle East. Over the next three thousand years this artificial semi-precious stone was re-invented elsewhere, for example in China and in West Africa, but using other chemical systems. The technological trajectory of glass was critically influenced by the invention of glass blowing in the first century BCE, which led to the development of the transparent and colourless material which is widely understood as glass today.
