When the water evaporated and the salt crystals reformed, a brown residue remained on the surface. I had it analyzed – it was nothing other than ordinary clay.
The "Himalayan salt" comes from Khewra, Pakistan, and is mined there under miserable conditions – poorly paid, with no hygiene regulations. It is mine salt, rejected by the industry because it is contaminated with iron and dirt.
And instead of throwing it away, they simply invented a clever marketing strategy – and now sell it as a supposed “miracle salt” for your table.

The black lava salt is salt that has been mixed/coated with carbon powder. If you dissolve it in water, you end up with black sediment at the bottom, and can even get the charcoal on your fingers if you rub it between your fingers. It's just for looks.

The red salt is similar, but is covered with red clay dust, again, just for looks, again, created a sediment in water if dissolved.
