They fill with graphite and must be kneaded clean.
A kneaded eraser fills with graphite and stops lifting — knead it clean often. And fix the final drawing lightly, or your carefully lifted lights will smear shut in the portfolio box.
Tone a page with willow charcoal, then draw a glass of water using only erasers: dab the soft window light, drag the streak down the glass, cut the sharp rim highlight. The drawing appears out of the dark.
A toned ground gives a ready middle value; subtractive drawing pulls lights out with erasers (lift out), so you draw in both directions — and the process itself is documentable experimentation.
