Cross-section examination is used to provide information about the layer structure of the painting and its condition.
We invite you to discover some pictures of examinations performed by cross-sections:

The three main layers can be observed:
The ground layers (yellowish layer),
Two paint layers (blue and light blue),
The varnish layer (brownish transparent layer on top).

SEM examination showed that the ground layers of the painting were affected by mould. This fungal growth belonged to the Aspergillus genus, commonly found on the canvas supports of oil paintings. Scientific scrutiny and close examination of suspect areas are essential for successful future treatment.
