We used two pens (a [[Pelikan 140]] for medium to small size and a [[Duofold]] De Luxe for medium-large size) to progressively empty the bottle of ink or the inkwell under examination by repeatedly filling them. The four methods to fill the pen from the bottle defined in the following paragraph were used, weighing the remaining residue for each of them with centigram accuracy using a balance.

Si è considerata (a parte l'ultimo caso) come limite di passaggio fra una modalità di caricamento all'altro il momento in cui, mantenendo quella modalità, non si riesce a caricare la penna in maniera significativa, assumendo come valore di "significativo" la quantità di 0,8 ml di inchiostro, in sostanza il contenuto di una cartuccia corta.

We regarded (apart from the last case) as the limit of passage between one filling mode and another the step in which, maintaining that mode, the pen cannot be filled in a significant way, assuming as "significant" the amount of 0.8 ml of ink, basically the content of a short cartridge.
