Scaling ceramic recipes without errors

First determine whether the recipe is a 100% base or includes additions above the base. A 3% colourant added to a 1000 g base means 30 g addition and 1030 g total dry mix.

Procedure

1. First determine whether the recipe is a 100% base or includes additions above the base. A 3% colourant added to a 1000 g base means 30 g addition and 1030 g total dry mix.
2. Do not round every ingredient too early. Keep calculation precision and round only to the resolution of the scale.
3. Save every changed recipe as a new dated test version instead of overwriting the original.
