Crackle

Crackle Process: Making a layer of paint that has been placed over another layer, crack, giving an aged look to new and old furniture, walls, almost any surface from paper to hard stones.
Sandwich in between the 2 layers, and because of the chemical action of the layers, the top layer is caused to separate and crack, revealing the underlying layer.
