Kiln Dried Solar Salt Crystals
Produced by the Sea, Extracted by the Sun
Perfect for the manufacture of quality bath salts
Kiln Dried Coarse Solar Salt Crystals: Coarse screened, white crystalline solid, manufactured by solar evaporation of seawater. The crystals are refined by washing with clean saturated brine to remove surface impurities, drrained of excess moisture, dried and screened to size.
Kiln Dried Coarse Solar Salt Crystals contain no anticaking or free-flowing additives or conditioners
