Salt and quartz

Postby Gamliel K » Tue Aug 10, 2010 5:09 pm


I’ve recently picked up a small polished quartz box at a museum gift shop with the idea that I’d use it as a salt box. However after getting home I vaguely remembered something from my high school geology class about quartz reacting with salt. Although I could be completely wrong.

Do you know if I should have any concerns to about using this box as a salt box?

My own memories of such things also go back to the days of high school so I am hardly a qualified chemist. I would think, however, that precisely the opposite of what you fear would take place. In Japan and other countries in areas near the sea windows are often coated with quartz and the exterior of houses are given a layer of quartz (as a silica coating) precisely because it avoids the harm that the salt water might otherwise do.

What the heck..give it a try. If you should notice pockmarks in the quartz a few years on you'll know I was wrong. Even if so, the minute quantity of quartz that you might ingest will do you no harm.
