Marquetry is the process of decorating an object's surface by cutting and fitting together many pieces of thin layers to create an image. It's often done with veneers, or thin sheets of material like hardwood.
Marbling is a method of decorating paper or fabric by floating pigments or colours on a sizing solution. Carrageen is used to develop the appropriate viscosity of the sizing solution to maintain the colours and pattern on the solution surface. The colours can then be combed or manipulated into various patterns.
