Rock Salt
C tier
Rock salt is mined halite in large crystals—industrial, de-icing, and culinary block or mill forms. Culinary rock salt should be food-grade; grey impurities vary. Flavour is plain salt when pure. Use for salt-crust baking, mills, and grinding. Not all rock salt on hardware shelves is food safe—check grade.

History
Underground salt mining supplied rock salt to early civilisations.
Industrial mining expanded rock salt for food and non-food uses.
Culinary rock salt mills and crust cooking kept food-grade rock salt in kitchens.
Distinction between food-grade and de-icing rock salt became a consumer safety note.
