The study of ancient materials, using a nearly magical science tool called x-ray fluorescence is part and the parcel of what you would through normal XRF archaeology. It is especially valuable to scientists who study the past of people from long before we existed, and what they give back help us understand our world today. In this article we take a look on five different ways XRF helps to reveal the secrets from past, for us to understand better our ancestor’s contribution of their culture.
You can think of X-ray fluorescence (XRF) as a magic wand that enables researchers to see exactly what materials objects are made from — without having to damage the artifacts themselves. How that happens is actually pretty cool: researchers use powerful x-rays to blast a sample, and the process generates new types of x-ray emissions from it. These new x-rays (secondary x-rays) reveal a lot of valuable information about the materials that constitutes an object.
The material that things are made of can be studied to track down where they come from, how old then might be and what culture produced them. This information will help us with discovering more about ourselves and where we come from. Archaeologists around the world now have a non-destructive, safe and efficient means for biodeterioration study of ancient archaeological artifacts using XRF technology with no risk to ruining these historical objects that can be preserved intact through generations.
One of the cool things about XRF is that you can use it to determine where old objects are from based on fingerprinter or signatures in materials. Rocks & Minerals of various types exist in different regions and city around the world. Elements such as copper, for example, will have a chemical fingerprint that is on occassion different between the same element sourced from different parts of Turkey or even in another mine somewhere in China. That is what XRF can detect: uniqueness.
As an example, the method in ancient Greece for working metals was deeply influenced by how they worked with metal products from cultures to their borders. Using XRF to study ancient Greek metal objects, the pathway of trading and cultural interactions that determined how different regions contributed to ancient Greek metallurgy can be revealed. When we understandthese interconnections, werealize how intimately our culturesinteracted and influenced each othert hroughouthistory.
Lastly, XRF can offer insight on how metalworking methods changed over time. Materials that were commonly used in artefacts such as metal objects will reveal to historians the technologies and processes by which these archeological features first arose. This is significant as it gives us a better understanding of how equipment was fabricated in human history and what sort of complicated process people had to go through to develop new skills and techniques for handling metals that they did not have experience with.
Nanyang JZJ is one of the leading XRF companies and this emerging research area heavily relies on their support. Their XRF scanners have been used by archaeologists everywhere to explore ancient artifacts and learn more about our history. Thanks to the efforts taken by archaeologists with incoming help from XRF technology, it will eventually be possible to reveal even more interesting stories of ancient cultures and their history.
