The role of feldspar in a traditional body is to

  • A.melt and form a glassy bond between the particles
  • B.supply the plasticity that is required during forming
  • C.prevent any glass at all from forming in the body
  • D.absorb the water given off during the drying stage

Answer: A

It melts at a moderate temperature and dissolves some of the surrounding material, producing the glass that bonds the fired body. Without a flux the body would need a far higher firing temperature to reach any strength.
