## Resource

Scientists have cracked a new method to spot fake ancient pottery by reading magnetic signals trapped in clay minerals—essentially, tiny compasses frozen in place when fired. Since Earth’s magnetic field shifts over time, the direction of magnetism in old vs. new pottery differs. Researchers found that authentic ancient pieces require extreme heat (over 112°C) to erase their magnetic signature, while modern fakes vanish at much lower temps. This breakthrough gives law enforcement a powerful tool to authenticate artifacts and combat illegal trafficking, all thanks to our planet’s ever-changing magnetic field.
