Crackle is a term used to refer to the paint aging procedure, which is one of the most common, simple and practical methods to carry out. This method develops hairline cracks that often occur on the surface of old oil paintings and furniture that has fallen apart over time. The cracking is caused naturally by the gradual and uneven contraction of the different layers of paint, putting a cover of synthetic base (slow drying) and another on water-based paint (fast drying) to obtain this effect. The synthetic colorant can dry slowly, causing surface stresses for a longer period of time, as a result of this, the synthetic paint that dried quickly, cracks following the displacement of the stresses of the base paint.

Although it may seem like a complicated technique, cracking is very simple. On some occasions, it is likely that by hastening the aging process, a uniform cracking does not always come out, since this will depend on the amount of paint, how the brushstrokes are made, and of many other factors that could mean that the method is difficult, however, it is not like that, it is only a changing process that through practice can be mastered. Any surface is suitable for applying this technique. The person can crack an object by acquiring a cracker or through home methods.

One of the most common cracking methods is detailed below: When the cracking agent is a single component, it must be applied between two colors that are different, the most advisable thing is to use colors that are not different, but that will depend on the craftsman . First, the area is painted in one color and allowed to dry. Then, using a brush, give a crackle coat that is neither too thin nor too thick and let it dry. The next step is to apply another layer of paint of a different color than the first, in this case it is best not to apply the paint in the same place so that the cracking is done properly.
