Since the mid-twentieth century, this activity has been facing a …

Where our salt comes from -- a dive into the spectacular …

Sea salt, harvested through the evaporation of seawater, is also a bit different than the salt mined from the earth. It retains trace minerals and elements, giving it a more complex flavor profile ...

Methods for calculating brine evaporation rates during salt production

These studies have tended to leave open the question of efficiency and total salt production, except in the few cases where historic descriptions of saltworks exist (e.g., Chiang, 1976). Few have attempted to quantify the process of evaporation. Quantifying the process of salt production does more than provide estimates for the total salt produced.
