This can be a result of our salt's unprocessed nature. Our salt is directly sourced from the Himalayan rocks and undergoes only grinding without any additional processing. It results from how the salt forms over time in mineral-rich deposits. These natural formations create irregular shapes and sizes that contribute to the texture.
Due to the natural origin of the rocks, there can be variations in the levels of certain natural elements. As a result, the elements you've observed might not dissolve as smoothly as desired.
