Ceramic Firing Loss at 110% firing loss assigned to this product or kiln: a worked example

Push firing loss assigned to this product or kiln up to 110% and the picture changes. This example computes every intermediate figure at that operating point. a ceramic plant needs to cost kiln-related scrap for a product, firing cycle, or line

The inputs for this scenario

  • Pieces lost during firing or kiln unloading: 1,200 pieces (unchanged)
  • Cost per fired piece lost: 2.75 $ / piece (unchanged)
  • Firing loss assigned to this product or kiln: 110 % (raised for this scenario; the documented default is 100)
  • Fixed kiln sorting, rework, or disposal cost: 650 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Allocated ceramic firing loss = pieces lost during firing or kiln unloading × cost per fired piece lost × allocation share) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,280 $ firing loss for ceramic firing loss, the number this scenario is built around.
  • At this operating point the engine returns 3.57 $ / piece for cost per fired piece lost.
  • At this operating point the engine returns 3,630 $ for allocated ceramic firing loss.
  • At this operating point the engine returns 650 $ for fixed kiln sorting, rework, or disposal cost.

How this compares with the baseline

  • Against the tool's baseline example, where firing loss assigned to this product or kiln sits at 100% and the headline result is 3,950 $ firing loss, this scenario comes in 8.35% above the baseline at 4,280 $ firing loss.
  • It computes total firing loss cost by multiplying lost pieces by cost per piece and an allocation share, then adding fixed sorting, rework, and disposal cost. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

  • Ceramic Firing Loss: 4,280 $ firing loss (headline result)
  • Cost per fired piece lost: 3.57 $ / piece
  • Allocated ceramic firing loss: 3,630 $
  • Fixed kiln sorting, rework, or disposal cost: 650 $
