Inkwell

An inkwell is a small jar or container, often made of glass, ceramic, or pewter, that is used for holding ink in a place that convenient for the person who is writing. The artist or writer dips their brush or dip pen into the inkwell as needed or uses the inkwell as the source for filling the reservoir of their fountain pen.

An inkwell usually has a hinged or screwed-on lid to prevent excessive exposure to air, contamination, evaporation, and accidental spillage.
