wine cooler? water evaporates through the clay and keeps wine cool.

oh ok, thanks...so the bottle would stick out the top and you would put ice down the sides?

The flat thing is actually a base or trivet. You soak the chiller in water and put it in the freezer for about 20 minutes or so and then take it out and put the bottle of wine in it. You can put ice in the very bottom but you don't have to.

Thank you so much for taking time to respond!
