What was the challenge or problem to solve?
How was it addressed or what was the solution?
To know the cause of failure, correct and defective samples were analyzed using electron microscopy techniques (SEM and EDX) with a Phenom ProX de Thermofischer Scientific.
Thanks to this, it was discovered that the veil that forms on the surface is derived from a higher concentration of metallic particles, which are not distributed homogeneously on the surface, and create that visual effect of different reflection of the incident light.
- Need to know the cause that generates the appearance of the veil in the painting
- Proposed solutions to prevent the failure from reoccurring
- Microscopic inspection of paint distribution
- Characterization of its elemental composition
