Crackle glaze

Designed to produce consistent cracking of emulsion paint. This acrylic medium creates dramatic two colour aged effects. The crackle glaze is applied over an emulsion base coat which will be the colour of the cracks. An emulsion top coat in the chosen colour is then applied over the glaze. The top coat cracks to reveal the base coat.

When it's dried it then is scanned into the computer and is now able to be used as a background layer in Photoshop. You can use these transfers to put on top of another image (a layer) then change the opacitiy so it makes a background. E.g can be used a background for a sky, a house, a studio background, a person etc.

Some images I found on the internet of what it can be like:
