Okay, then I shall find a way to attach a chunk of the crystal to a lamp or two 
here and there, and see what happens.  Er - how would I know if it worked, 
anyway?  

I guess I could use wire or something attached to the lampshade close to the 
top of the bulb to get the most heat/light - in fact, both lamps I am thinking 
of trying this with have glass lampshades anyway.  

- Okay, that's done.  One smallish piece I just jammed in a space near the 
bottom of the lampshade between the glass and the metal frame, and the other 
piece I was able to carve a little bit (I pounded with a variety of implements 
to try to smash the crystal, unsuccessfully) and jammed the resulting groove 
into the ornate metal finial at the top of the lampshade.  

To bring this slightly back on topic: the instructions say to drop the crystals 
in a jar and top up with water; I topped up with CS.  When I take it, I put a 
teaspoonful or so (i.e. one "slosh") in a glass of water; if it's too salty I 
add water and just drink  to make room and top up with water until it tastes 
right.

  Its a big chuck of Himalayan rock salt with a whole put in the bottom of it.A 
removable lamp with a 7 - 15 or 25 watt bulb
  is placed in it.Most of the sellers say the heat from the light
  causes the salt to release negative ions.
  One site thinks it the light waves that cause it to release
  the negative ions.!
