What is the nature of the 'Sodomite salt' mentioned by the Sages—is it extremely fine salt, or coarse salt as hard as stone?

This source-based Torah study examines the question: What is the nature of the 'Sodomite salt' mentioned by the Sages—is it extremely fine salt, or coarse salt as hard as stone? The canonical Hebrew discussion develops the issue through the weekly Torah portion and the classical sources cited there, preserving the distinctions and tensions of the original unit. This localized layer is a discovery-oriented summary rather than a full translation of the article, and it does not add a new halakhic, medical, legal, historical, mystical or empirical ruling or claim beyond the canonical source. Any practical conclusion remains subject to the unit’s canonical review status.
