Final answer:
The term for artwork using small pieces of colored glass, stone, or tile embedded in plaster or mortar is a Mosaic (Option A). Mosaics are known for their durability and visual appeal, traditionally used in various historical contexts on floors, ceilings, and walls.
Step-by-step explanation:
The answer to the student's question is A) Mosaic. A mosaic is an art form that consists of creating images or patterns using small pieces of colored glass, stone, or ceramic, known as tesserae. These pieces are embedded in a material such as plaster or mortar to form a unified image. Mosaics have been used throughout history, from ancient Roman times, where they decorated public baths and villas, to Byzantine churches and even modern-day art.
Mosaics stand out for their durability and the ability of the tesserae to come together and create detailed, vibrant pictures or patterns, whether they're on walls, ceilings, or floors. Artists first sketch a design and then carefully place and glue the tesserae onto the surface. When the glue dries, grout is spread over the top to seal and protect the artwork. Due to their complexity, mosaics require patience and precision to produce.
