ALICE detects the conversion of lead into gold at the Large Hadron Collider
- Physicists at CERN's Large Hadron Collider observed the conversion of lead into microscopic amounts of gold between 2015 and 2018 near Geneva, Switzerland.
- This transmutation occurred during high-speed lead-lead collisions that recreated quark-gluon plasma, enabling nuclear interactions that knocked protons from lead nuclei to form gold.
- The ALICE detector, designed to study early-universe conditions, measured about 86 billion gold nuclei with extreme sensitivity despite not being built to produce gold.
- The total gold mass produced was only 29 picograms, lasting microseconds before disintegrating, and the production rate reached about 89,000 nuclei per second as reported by ALICE spokesperson Marco Van Leeuwen.
- Although this realization fulfilled a centuries-old alchemical dream, the minuscule quantity and brief existence of the gold highlight the process's impracticality beyond scientific insights into nuclear and electromagnetic phenomena.

ALYCE is a physical witness to transform lead into gold!
We know that on Earth we have not been able to produce gold in practice or in large quantities — at least not with current technology. And we have already explained how this noble metal has reached the planet. However,...
Transmuting Lead into Gold, CERN's Large Hadron Collider Achieves Alchemist’s Dreams for a Fraction of a Second
CERN’s Large Hadron Collider has momentarily transformed lead into gold, the long-sought-after goal of medieval alchemists, as confirmed by recent experiments conducted with the ALICE detector. Long relegated to fiction and myth, chrysopoeia, or the pursuit of transmuting lead into gold, was impossible until 20th-century nuclear physics. Although the elements share similar densities, their chemical natures are distinct, although some earlier lab…
