Consider the following statements about whiteware classification.
1. Earthenware retains open porosity after firing.
2. Porcelain is vitrified and translucent.
3. Stoneware is more porous than earthenware.

  • A.3 only
  • B.1 only
  • C.All of them
  • D.1 and 2 only

Answer: D

The first two are correct. The third has the order wrong, since stoneware is vitrified and denser than earthenware while stopping short of the translucency of porcelain. The three classes form a sequence of increasing vitrification.
