MvdV> Several years ago, here in the local supermarket, there was this young
 MvdV> girl trying to market a "new" product: "biological
soup". She claimed
 MvdV> pure rock salt was used in its preparation. So I queried her about the
 MvdV> "pureness" of the rock salt. Unrefined, nothing added,
nothing removed,
 MvdV> pure from mother nature she said.

After having seen the "salt lakes" in Thailand and how they do
it, only sand is
added.
