Why spend time freezing water when you can use the purest form of rock again and again? Swedish base rock is incredibly pure, which isn't always the case for tap water, and the rocks go by many names, including Nordic Rocks, Swedish Ice Cubes, and Viking Ice Cubes. Apparently after putting them in a freezer for an hour, they will cool your drink slowly, so there's no need for extra ice cubes. Has anyone ever used these?
These rock cubes have been around for quite some time adorning Scandinavian drinks. We couldn't find much information about Swedish base rock, but all of the Swedes we know said it was common knowledge, and they call it "pollution free" because the rock formed prior to the industrial age in an area where there are only a few inhabitants.
Now these rocks are slowly catching on as a global phenomena. By replacing your normal ice cubes with these rock cubes, you can save both water and energy. A typical ice cube tray uses 5 teaspoons of water to create 16 ice cubes.
They come in sets of 10 with their own leather storage pouch to keep them clean, cool, and ready to use. You can find these Swedish Base Rock's online at Mocha, a husband-wife business based in the UK, who specialize in unique and modern gifts.
