General Physical Description: (Raw Industrial Salt)
- Appearance: Large, irregular crystals or “grit.”
- Colour: Off-white to light grey (due to natural minerals and clay).
- Texture: Coarse, hard, and moist. It typically contains a higher moisture content as it is not kiln-dried.
- Impurities: May contain traces of sand, grit, or insoluble sea minerals.
Specifications: (Refined Industrial Salt)
