Optically Stimulated Luminescence (OSL) Masterclass (Patreon)

Some archaeological sites have very few artefacts, and that can cause us a major headache when it comes to dating them. That was certainly a concern for us at Kielder, where we weren’t expecting the site to be particularly rich in finds.

Luckily, we were joined by some wonderful OSL specialists from the University of St Andrews, who had a rather clever way of helping us unlock the site's chronology.

So, what exactly is Optically Stimulated Luminescence, or OSL, and how can it help archaeologists date a site when there are few, or even no, artefacts to work with?

In this mini Masterclass, we’ll take a closer look at OSL, how it works, what it can tell us about the past, and how it helped us understand the archaeology at Kielder.
