ceramic water dispensers?

[geochem]

One thing to be aware of with those ceramic dispensers: you can't set it on anything that responds to water: a wood countertop, or a table. The bottom of the ones I've had and seen have unglazed ceramic on the bottom and a small amount of water leaks through - I think the intent is for it to evaporate and cool the water in the container (as it does on those wooden framework stands) but if you set it flat on a table it will damage the finish on the wood.
