What is the art technique made from small pieces of glass and stone, often used on walls?

• A. Fresco
• B. Mural
• C. Mosaic
• D. Tapestry

Answer: (C)

Mosaic is the art technique that uses small pieces of glass and stone arranged to form pictures or patterns on a surface. These tiny pieces, called tesserae, are set in mortar or adhesive and then grouted to hold them in place. This method is especially associated with walls and ceilings in buildings, creating colorful, durable designs.

Fresco involves painting on fresh plaster, so no separate pieces are used. A mural is a large painting applied directly to a wall, typically painted rather than assembled from small fragments. Tapestry is a woven textile hung on a wall, not made from glass or stone. So mosaic best fits the description.
