X-ray fluorescence

Definition

X-ray fluorescence (XRF) is a non-destructive analytical technique used to determine the elemental composition of materials by measuring the fluorescent X-rays emitted from a sample when it is excited by an X-ray source. This technique is crucial in the analysis of artifacts, including glasswork from ancient Rome, allowing researchers to identify the chemical elements present in the glass and understand its production techniques and historical context.

5 Must Know Facts For Your Next Test

1. X-ray fluorescence can analyze solid, liquid, and powder samples, making it versatile for studying various types of artifacts.
2. The technique can provide information on trace elements, which are vital for determining the origin and production methods of Roman glass.
3. XRF is widely used in conservation efforts because it allows for the identification of harmful elements without damaging the artifacts.
4. Portable XRF devices enable on-site analysis, which is beneficial for archaeologists studying glasswork in situ.
5. This technology has revolutionized the field of art history and archaeology by providing detailed insights into ancient manufacturing techniques and trade routes.
