Many retailers will have a disclaimer regarding their pots advising that they aren't frost proof.
Many years ago I think I was instrumental (or maybe I was one of a number of people who complained) in getting Wyevale to stop advertising ranges of pots as "frost resistant."
When I complained that the four I'd bought had "blown out," in freezing weather, I wasn't having the "They are only frost resistant sir." As I pointed out they hadn't resisted at all. So got my money back.
They stopped advertising them as such.
We've about a dozen high glaze ceramic pots of 12" or larger on our patio for roses etc.,(the ones that blew out weren't glazed). I used to go to the trouble of wrapping the pots in several layers of bubblewrap each winter. They all sit on pot movers so are not in contact the the patio. But for the last couple of years I've not bothered. Neither the pots or the contents have suffered over the winter. Though they do "huddle together like Antarctic penguins."
