Why did my glass drinking container break when I put the nuggets in?
The glass was not strong enough to withstand clunking nuggets. If you are concerned about the nuggets breaking the glass, an alternative way of energizing water is to use the Shungite S4 laminated sticker. You would need to use it like a coaster. The container would just sit on top of the laminated sticker. The same energizing to the water will occur as if you had nuggets of Shungite in the water.
