I have also seen similar centerpieces that use epsom salts instead of sugar. You could also sprinkle a mix of pearls/gems. Sand (or sugar), faux pearls, a 3 candle. An easy DIY wedding centerpiece idea.
Lovely DIY for scented homemade bath salts (using essential oils). 6 parts coarse sea salt, 3 parts epsom salts, 1 part baking soda and a few drops essential oils = homemade bath salts. Great for Gift Baskets
