What Is Rock Salt, And What Is It Used For?

Also known as “Halite”, bagged salt is a mineral that has a long history of usage across various cultures and industries. It tastes like table salt and looks like large crystals. But what exactly is bagged salt, and how is it used? Let’s delve into this fascinating mineral.

Understanding Bagged Salt: An Overview

Salt is the mineral form of sodium chloride (NaCl). It’s found within sedimentary rocks and gets mined in various parts of the world, including the United States, Canada, Germany, and the United Kingdom. Available in a variety of colours, from colourless to white, red, grey, brown, yellow, and blue, it gets its colouration from impurities and the surrounding soil.

The Formation Of Bagged Salt

Bagged salt is usually formed from the evaporation of salty water found in seas or saltwater lakes. Over hundreds of thousands of years, the areas turn dry and leave behind large deposits of minerals, including salt. These deposits are then buried under sediment layers which, over time, turn into the bagged salt deposits that we mine.

Main Uses Of Salt

  • Deicing: One of the most common uses of bagged salt is in the de-icing of roads and walkways during winter. Salt lowers the freezing point of water, thereby preventing ice formation, and helps in melting existing ice.
  • Cooking: Although table salt is more common for cooking, bagged salt has its place in the kitchen. It’s often used in cooking methods such as salt roasting, where food is either cooked on a bed of salt or enclosed in a salt crust.
  • Health and Wellness: rock salt is also popular in health and wellness practices. Therapeutic salt rooms or caves use bagged salt for its reported health benefits, ranging from improving skin condition to easing respiratory problems.
  • Salt Lamps: Carved blocks of bagged salt can also be used as lamps, where a bulb inside heats up the rock, releasing negative ions believed to have health benefits.

The Impact Of Bagged salt

Despite its benefits, the use of bagged salt doesn’t come without any impact. The primary concern associated with bagged salt is environmental.

  • Environmental Impact: When used as a de-icer, bagged salt can find its way into water systems, causing salt pollution that harms wildlife and affects drinking water. It’s important to be careful and conscious about the amount of salt used for de-icing purposes.
  • Corrosive Effects: Bagged salt can be corrosive to certain metals and concrete, causing damage to infrastructure and vehicles over time.


Bagged salt, or halite, is a versatile mineral with a wide array of uses spanning industries such as culinary, wellness, lighting, and winter road safety. Despite its usefulness, it’s crucial to use bagged salt responsibly, considering its potential environmental and corrosive impacts.
