VCT is made of clay fired to a glass-like material that is highly abrasion resistant and resistant to corrosive chemicals.

• A. oxidizing agents
• B. water damage
• C. corrosive chemicals
• D. base metals

Answer: (C)

Vitrified ceramic tile is created by firing clay until it forms a dense, glass-like surface. This vitrification makes the tile very hard, giving it excellent abrasion resistance, and also makes the surface chemically inert and less permeable. Because of that dense, glassy matrix, the tile stands up well to attack from corrosive chemicals, which is why it’s described as resistant to corrosives. Among the options, corrosive chemicals best fits what the material is designed to withstand without deteriorating. While a vitrified surface also resists moisture due to its low porosity, the characteristic highlighted in the description is its chemical resistance, particularly to corrosive substances.
