Are these impurities in rock salt or added later.
The reason I ask is my wife bought a rock salt lamp, basically a lump
of salt hollowed out with a flex and bulb inside to give a translucent
effect.
On wet days (it's 20C with a 68% RH here) a pool of brine collects at
the base, this then evaporates leaving a film of salt crystals. I
assumed it was the NaCl that was hygroscopic.
