Forming of salt crystals

The salt crystals form or ‘set’ on the surface of the brine before sinking to the bottom of the pan. The fiercer the burn, the finer the grade of salt crystals, there were fine salt pans and common pans, the latter produced coarser salt for other industries to use. Seddon’s also produced large salt crystals known as ‘Lagos’ Salt, it was used as money in a province of Africa.
