Which term refers to the process of fusing colored glass layers together?

• A. Horizon line
• B. Flashing
• C. Fresco
• D. Impasto

Answer: (B)

This question tests terminology used in glass arts and how colors are combined. When glass layers are joined by heat to become one piece, the technique is flashing—laying a thin sheet of colored glass over a base and then fusing them together in a kiln. This creates a layered color effect without needing a full thickness of the second color, giving depth and subtlety to the finished piece.

The other terms come from different areas. A horizon line is a guide in drawing that establishes eye level and perspective. Fresco is a painting method done on wet plaster. Impasto describes applying paint in thick, textured layers.
