[Clayart] durable outdoor planters

[Lis]

It is my understanding that the reason they crack in the freezing is 
that water gets absorbed into the clay body. So the secret seems to be 
to make sure water can't get in, ie. fully and properly glaze them, 
inside and out, and maybe raise them slightly up above ground level if 
you are leaving them out all winter.

The only pottery thing I have been leaving out is a small Fairy House. 
It is fully glazed and sits on a small rock. It has been out in -30C 
weather for 5 years so far.
