What is the difference between a collage and mosaic?

A collage and a mosaic are both forms of artwork that involve the arrangement of various elements to create a visual composition. However, there are distinctions between the two.

A collage is created by assembling various materials such as paper, photographs, fabric, or other objects, typically onto a flat surface like canvas or paper. These materials can be cut, torn, or arranged in any way the artist desires to create a desired image or composition. Collages often emphasize the combination and juxtaposition of different textures, colors, patterns, and images to convey a specific message or aesthetic. They can be 2-dimensional or 3-dimensional, and the final piece is typically flat.

On the other hand, a mosaic uses small pieces of materials (usually glass, tiles, stones, or other hard materials) to form an image or pattern. These materials, referred to as tesserae, are individually set into a base material (such as cement, grout, or adhesive) to create a design. Mosaics can be used to decorate floors, walls, ceilings, or other surfaces. They can be 2-dimensional or 3-dimensional, and the final piece has a textured, uneven surface due to the placement of individual tesserae.

In summary, the key difference between a collage and a mosaic lies in the materials used and the way they are arranged. A collage uses various materials, typically flat, and they are assembled together creating a flat composition. A mosaic, on the other hand, uses small tesserae generally made of hard materials to form an image or pattern on a surface, resulting in a textured, uneven final piece.
