Great idea. Do you glaze them?
Mark, you really can. I make whiskey cups with porcelain ice cubes. You keep the porcelain cubes in the freezer and use them like regular ice cubes. It cools your whiskey almost as well as ice cubes and, best of all, it doesn't dilute good whiskey.
Diane... No, the porcelain "ice cubes" aren't glazed. I can't put a picture into a post so I have to put them in my profile gallery (and will delete them after a while). Here is a picture of two whiskey cups with cubes: http://ceramicartsda...wimage&img=2705
