This refillable 1.6 oz glass grinder is a perfect addition to your dining table and kitchen! It is filled with a coarser crystal suitable for grinding and has the same great flavor you've come to expect from our Heirloom salt. Refill with our 1 lb bag of grinding salt. Sourced from an ancient 400 million year old, untouched sea called the Iapetus Ocean – predating the Atlantic Ocean, yet trapped below the Appalachian mountains — our salt is free of contaminants and heavy metals that may be found in other oceans. Gleaned from the earth by an underground brine aquifer at JQ Dickinson Salt Works in Malden, WV; the salt brine is then processed naturally using the power of the sun and gentle mountain breezes in special sun-houses and hand harvested, to create a perfect farm-to-table salt for any type of dish.
