A bowl of ground black salt (kala namak), a fine pinkish-grey powder
Composition
USDA FoodData Central (SR Legacy), adapted · 173468. No dataset carries kala namak specifically. It is a rock salt with trace sulphur compounds, iron and other minerals, which give it its colour and its distinctive sulphurous smell, but it is overwhelmingly sodium chloride by mass like any other rock or table salt. The sodium figure here is scaled down slightly from the site's plain table salt record (173468, 38,758 mg/100g) to reflect its somewhat lower typical purity, and the density is the same solid-salt class used for table salt: the crystal itself, not a measured figure for this specific mineral.
