In the physical world, nature’s "kiln" is the Earth’s mantle, approximately 90–125 miles below the surface.
Temperatures must reach at least 2,200 degrees Fahrenheit with a pressure of roughly 727,000 pounds per square inch .
For those who can't wait a billion years, modern technology uses "lab kilns" through two primary methods:
Natural diamonds can take anywhere from a few days to 1 to 3 billion years to fully crystallize.
Carbon atoms, the same building blocks found in coal and all living things.
