Laminations in an extruded ceramic product arise chiefly from

  • A.the body containing far too little water in it
  • B.cutting the moving column altogether too slowly
  • C.the auger folding the body over on itself
  • D.the die being much too large for the extruded column

Answer: C

Correct answer: the auger folding the body over on itself

The auger drives the body forward in a helical path, and the successive turns meet as surfaces which do not always knit. Those interfaces are laminations: invisible in the wet column, and revealed as curved cracks when the drying or firing stresses find them.
