What if you had a large and very hot sphere (made of a a thick alloy/material with a higher melting point than any of the elements) and you fired in the 94 natural elements to collide in equal parts in the center and make a ball that fits the sphere? The solid elements would be in a powdered form, and the gases would not be allowed to escape. The sphere would be heated to 4000 degrees Celsius, pressurized at 10 atmospheres, and spun at a rate of 100 revolutions per second. Then it is slowed down, the pressure released, and rapidly cooled to -100. Then the ball of elements is taken from the encasing sphere (Let's assume it doesn't stick), and allowed to return to room temperature. What will it be like? Will it react with itself and burn/explode/melt, or will it reach an equilibrium? Couldn't you do something similar to replicate the formation of the Earth? Getting all the elements, not in equal proportions, but in the proportions found in nature, putting them in a ball, heating them to the temperature of the early Earth, spinning them at a rate that the planet spun at, and so on?
