Which tile type has a smooth surface, is denser, and has an impervious body with absorption less than 0.5%?

Which tile type has a smooth surface, is denser, and has an impervious body with absorption less than 0.5%?

• A. Unglazed ceramic
• B. Glazed porcelain
• C. Ceramic mosaic
• D. Quarry tile

Answer: (B)

Tiles that offer a smooth surface, a dense body, and very low water absorption are glazed porcelain tiles. The glaze coats the surface, giving that smooth, easy-to-clean finish, while the body is fired into a vitrified, dense form that minimizes porosity. That combination yields an impervious tile with absorption typically under 0.5%. Unglazed ceramic lacks the glaze, so its surface is rougher and its body more porous, leading to higher absorption. Quarry tile is usually unglazed and porous as well, and ceramic mosaic can be less dense than porcelain, so it doesn't consistently meet the same very low absorption standard.
