A glaze slop is used at a specific gravity of 1.45 and a piece picks up 12 grams of glaze. If the slop is thinned to 1.35 and dwell time is unchanged, the pick-up will most likely be

  • A.exactly 12 grams still
  • B.impossible to predict at all
  • C.less than 12 grams
  • D.more than 12 grams

Answer: C

A thinner slop carries less solid per unit volume absorbed, so the deposited weight falls. Specific gravity is checked frequently in production for exactly this reason. A drifting slop shows up as uneven glaze thickness across a run.
