What are the cracks in old paintings?
Perhaps the most obvious characteristic of ageing observed on most old paintings is the network of cracks – known as craquelure – caused by the different mechanical behaviour of the various layers (such as the support, ground and paint layers).
Do oil paintings crack when rolled?
If rolled outwards, the painting is stretched, and if there is any hairline cracking, these will be invisible when the painting is laid flat again. Rolling oil paintings inwards causes the paint to crease, chip or flake, which become clearly visible when the painting is laid flat again.

Paintings should be stored flat or re-stretched promptly. Do not leave pictures rolled for long periods in storage.
Why are old paintings cracked?
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.
Why did my painting crack?
Cracking occurs in acrylic paint pours when the top layer of paint dries faster than the underlying layer. As the bottom layer dries, it pulls at the semi-hardened skin on top and when the force is too much, a crack is created. Newly formed cracks will continue to widen until the paint is fully dried.
How do you store oil paintings?
Make sure to store paintings in an area of a suitable temperature, meaning that the temperature should be moderate with 45-55% humidity and 65-70 F and in a dark place. Lastly, remember that a freshly painted oil painting shouldn’t be touched 18-24 hours after creation to avoid ruining it.
