Open Pan Salt Making
In Europe virtually all domestic salt is obtained by solution mining of underground salt formations although some is still obtained by the solar evaporation of sea water. Salt is extracted from the Brine using vacuum pans, where brine is heated in a partial vacuum in order to lower the boiling point. In the past salt has been extracted by heating the brine in pans operating at normal atmospheric pressure, known as open pans.

“The role of the writer is not simply to arrange Being according to his own lights; he must also serve as a medium to Being and remain open to its often unfathomable dictates. This is the only way the work can transcend its creator and radiate its meaning further than the author himself can see or perceive.”
—Václav Havel (b. 1936)
“When Pan sounds up his minstrelsy;
His minstrelsy! O base! This quill,
Which at my mouth with wind I fill,
Puts me in mind, though her I miss,
That still my Syrinx’ lips I kiss.”
—John Lyly (1553–1606)
“Unquiet wanderer
Draw the Glasnevin coverlet anew
About your head till the dust stops your ear,
The time for you to taste of that salt breath
And listen at the corners has not come;
You had enough of sorrow before death—”
—William Butler Yeats (1865–1939)
“It is wonderful how well watered this country is.... Generally, you may go any direction in a canoe, by making frequent but not very long portages.”
—Henry David Thoreau (1817–1862)
