Bittern (salt)

Bittern is like the leftover juice when you make table salt from seawater. When seawater dries up, the regular salt (called halite) comes out first. What's left behind is a super salty liquid called bittern. It's not just salty water; it's packed with other minerals like magnesium and calcium, which are important for our bodies!

You can find bittern in special places called salt ponds. These are large, shallow pools where the sun and wind help the water evaporate. Big salt-making factories use these ponds. Sometimes, even places that make fresh water from salty water (called desalination plants) have leftover salty liquid that becomes bittern. It's like a special mineral soup!

Bittern has some amazing jobs! It's a great source of magnesium, which your body needs. Did you know it can help make tofu? It acts like a glue to help the soy milk turn into soft blocks. It can also help clean up dirty water from factories, making it safe again. It’s a natural helper!

Making bittern is all about evaporation. When water evaporates, it leaves dissolved things behind. In salt ponds, the water disappears, and the regular salt (halite) forms crystals. The bittern is the concentrated liquid that remains, holding all the other dissolved minerals. It's a clever way nature separates different salts.
