Craquelure

Although I'm not a conservator or connoisseur, I knew from my art history background that craquelure is the pattern of fine cracks that occur in old paintings. What I didn't know, however, is that there are different types of crack patterns. Craquelure can be further classified into French craquelure, Dutch craquelure, Flemish craquelure, and Italian craquelure. Check out this interesting study.
