Analysing Historic Paintings with Micro-XRF
The National Gallery in London used micro-XRF to reveal a hidden sketch on a Leonardo da Vinci painting, which is the focus of their current exhibition. Micro-XRF is a non-destructive technique for mapping elements and analysing layers.

Micro-XRF at The National Gallery
The National Gallery in London used the Bruker M6 JETSTREAM to help reveal the secrets of Leonardo da Vinci’s painting “The Virgin on the Rocks”.
The painting is the focus of The National Gallery’s exhibition “Leonardo: Experience a Masterpiece”.
Researchers discovered completely different underdrawing under the layers of paint. This suggests that Leonardo sketched out one composition, then changed it to another for the final painting.
Macro-XRF was used to map elements on the painting. The materials used for the hidden drawing contained zinc, so the zinc map revealed the hidden lines. Macro-XRF is non-destructive, so it’s ideal for analysing valuable, historic paintings without damaging them.
The exhibition is on at The National Gallery until 26th January 2020. Details here…
Here’s a quick 30 second introduction from the gallery about the fascinating secrets of the painting:

Analysing Paintings with Micro-XRF
As a non-destructive technique, micro-XRF is ideal for studying paintings, artwork and historical artefacts. By measuring elements and mapping their distribution, you can acquire valuable information about:
- Authenticity of paintings
- Hidden layers
- Alterations, contamination and previous restoration
- Pigments used in the paint and materials
- Information for restoration and conservation
