Craquelure is the term we use to describe the visible network of cracks on the surface of a painting or object. This cracking is caused by the shrinking of paint or canvas. Craquelure without a consistent, regular pattern can be indicative of natural aging of paint over time.
What is crazing on a painting?
The crazing is due to the top layer of the painting drying faster than the bottom layer. The top layer forms a skin and hardens whilst stretching but the underlay is still wet and trying to dry. The top layer literally cracks through this stress.
