'They have calculated that a Roman brick sample with a known age of about 2,000 years was 2,001 years old. A further sample with a known age of between 708 and 758 years was calculated to have an age of 748 years.
The researchers also tested a 'mystery brick', with the real age only revealed to them once they had completed their process. The known age was between 339 and 344 years - and the new technique suggested the brick was 340 years old. '
Wow. That’s pretty amazing.
Thanks!
