Craquelure

Craquelure (French: craquelé, Italian: crettatura) - this is a special and unique structure of small cracks on the surface of the materials appearing either as part of the aging process, or a special form in a process of creating works of art.
This term is often found in tempera and oil painting, and is a sign of the age of the product, helping to detect counterfeit works of art, as craquelure is the "authenticity of the signature." There are various so-called French, Italian, Flemish, English and Dutch "styles" cracelures related to differences in the typical methods used by artists. Distinctiveness of these styles has been largely confirmed by various studies.
