The term 'Mosaic Component' refers to a TESSERA, which is a small piece of material used to create a mosaic. A TESSERA is typically made of stone, tile, glass, or other materials and is used to form a pattern or image when placed together with other tesserae. The tesserae are usually cut into small, uniform shapes and then arranged in a specific pattern. Mosaic art has been around for centuries and is still popular today.
