About The Blue Salt
Geological Origin and Formation Process
Ancient Seas and Evaporite Deposits
Approximately 200 million years ago, during the Late Triassic to Early Jurassic period, the region now known as Persia was covered by vast inland seas. Over millennia, as these saline waters slowly evaporated, thick layers of halite (rock salt) were deposited on the seabed in an environment that alternated between wet marine incursions and arid evaporative conditions.
High-Pressure Mineral Crystallization
Following deposition, these salt beds were buried beneath heavy layers of sediment and subjected to significant geological pressures and temperatures. Under these conditions, unique crystallographic changes occurred, facilitating the formation of crystalline impurities like sylvite (potassium chloride) embedded within the halite matrix.
The presence of sylvite and trace elements under pressure is what produces the salt’s characteristic blue hue—a phenomenon rarely observed globally, making this salt’s coloration a product of complex mineral physics and geochemistry.
Geological Uniqueness
Unlike common salts, the blue salt deposits are found exclusively in this region, where the geological conditions created the perfect combination of:
• High purity salt layers
• Mineral impurities crystallized in unique forms
• Slow geological uplift preserving the salt’s crystal integrity
Physical and Chemical Properties
• Crystal Structure: Cubic halite crystals interspersed with sylvite inclusions.
• Color Range: Deep sapphire blue to lighter ice-blue, with occasional white and gray streaks.
• Texture: Coarse grains with a firm, crunchy mouthfeel; dissolves evenly for flavor layering.
• Solubility: Standard for halite salts; ideal for culinary applications.
• pH: Neutral to mildly alkaline, depending on mineral ratios.
