Plasticity in a traditional ceramic body comes chiefly from

  • A.air that has been trapped between the particles
  • B.plate-like clay particles sliding over a water film
  • C.a chemical reaction between the clay and the water
  • D.the melting of the fluxes contained in the body

Answer: B

Correct answer: plate-like clay particles sliding over a water film

Clay minerals are thin plates, and a film of water between them lets them slide past one another while surface tension holds them together. Both halves matter: the shape of the particles allows the sliding and the water film both lubricates and binds. Take the water away and the body is rigid; add too much and it flows.
