How to make a Salt Lamp? Answered

I'd like to learn how to make a Salt Lamp. I've seen Himalayan Salt Lamps for sale, however himalayan salt contains uranium! So I'd like to know how to make one myself, perhaps from sea salt or rock salt or something. If anyone knows how to do this, please share your knowledge!


The color comes from impurities in the salt (in this case uranium oxide, a.k.a. "yellowcake").  You could make your own by purchasing your very own lump of rock salt with whatever impurities (i.e., from whatever mine) give it the color you want.  Try eBay.

The color is from the minerals in it.

If I use white salt rock it could be given a yellow - or other colour - glow by using a coloured globe. A much healthier option than uranium!

The first bag of testes I found tells me this is just rock-salt (i.e. salt) with a light inside it.

You need a lump of rock-salt, a drill and a light.


Interesting that they're touting ionizing radiation as a good thing.  Maybe I don't have to wear my dosimeter badge at work any more....

I don't know who SLAC buys them from, but they say "luxel+ LANDAUER" on the front.  They're the hexagonal plastic packs with the grey hexagonal clip.

"onsite turnkey analysis systems"... Thanks, that's of interest.


On an additional - you are surely aware that ionising radiation has been touted (in ignorance) as beneficial in the past?

I have a recollection that Pierre Curie had this idea, for one.


Oh, yes.  Ignorance is eternal, isn't it?

Yes, it explains more than 50% of election results (and always has)


Bag of testes? Oh man, I am cracking up over that! The link made it much easier to understand how these are made, thanks!
