The word 'potstone' originates from Old English, where 'pot' refers to a vessel for cooking or holding liquids, and 'stone' refers to a hard, solid mineral material. Therefore, 'potstone' describes a type of stone used in the making of pots or a stone associated with pots.
Think of a 'vessel' ('pot') made from a 'hard material' ('stone') — that's why 'potstone' refers to a stone used for making pots.
