I had a lot of ware on drying boards and was a little concerned with how it might deal with freezing and then thawing again. So far, the bowls I'd thrown the day before seem to be doing well. I trimmed them up today and though I'd planned to carve their rims, I decided to just leave them uncarved instead of putting more time into them just in case they did have some problem that hadn't shown up yet.
I also had a couple dozen mugs in two different shapes on drying boards. They had been trimmed and handled a few days ago and were covered in plastic to slow dry. When I first checked them yesterday they had significant ice crystals that had formed on them.

Anyway, while I don't think this is something I'd ever intend to do, it has been a great learning opportunity on what happens when water is forced out of clay under freezing conditions. And of course an excellent reminder to make sure the door is tightly closed before going to bed. Just goes to show, we're never too old to learn.
Be well. And make sure your doors are closed!!
