Unprocessed or unrefined salt present in natural or raw state.
Salt is extracted from salt mines (the mineral is called halite) or from sea waters.
The unrefined sea salt has a very small amount of iodine.
where is rock salt on the moths hardness scale
Salt for human consumption is produced in three different forms: unrefined salt (such as sea salt), refined salt (table salt), and iodized salt.

Penzeys sea salt is typically considered unrefined sea salt, as it is harvested from seawater and undergoes minimal processing. This means it retains some of the trace minerals found in the ocean. However, to confirm specific details about Penzeys products, it's best to check the packaging or the company's website for the most accurate information.
Two methods:- comparison with other materials with known hardness- using a special instrument to measure hardness
The Mohs hardness of of NaCl is 2,5.
Salt is sometimes used to remove water hardness. Borax and soda are generally used as well to remove water hardness.
Temporary hardness of water: CaHCO3, MgHCO3 Permanent hardness of water: CaSO4, MgSO4
