Any one had Tokoname pots cracked from being on the ground over winter?

This week, I noticed 2 of my Tokoname pots ( 1 large Robin egg Koyo and the other one is unglazed Shuho) were cracked when I went to lift them off the ground and to put them on the display stand. I believe this is the first time this happened to me. We had a very cold winter this year and rather quickly warm up, Im wondering if thats the case. Have anyone else experienced this? Thanks

I personally haven't experienced but i read somewhere that tokoname pots can crack in the cold. So best to protect em and make sure they're frost-resistant.

Alot can depend on the shape of the pot and how it was stored. Pots with incurved top lips can crack as soil expands when frozen for instance. Freezing mulch can also put stress on the pot from the exterior. FWIW I haven't pulled my pots out of the mulch piles yet to check this year. We got to 3 F a couple of nights so who knows....fingers crossed.

Sorry for your loss.
Another type of pot that I'm never getting is added to the list. Thank you for your unfortunate and unintended sacrifice.

I’ve had Tokoname pots (lots of them) for thirty years. Never had a casualty from freezing and some have seen below 0 F a few times. Any pot can crack if it’s subject to the right conditions. Some are more prone like some Chinese made pots and even some western made pots

I can second Rockm post, I have around 20 tokoname pots from different makers, they have all been purchased from Matt O.
I set them on the ground in the winter.
The coldest temperature these pots have experienced is 9 degrees with no cracking.
All my pots are unglazed clay.

Fwiw SUSTAINED heavy freezing what cracks pots. The cold freezes the soil through and freezing expands water (ice) if the pot has incurved overhanging lip or a point where the design has a narrower mid point or some other constriction that won’t let the soil expand (upwards) against the sides the pot will crack. Also if the pot has a crack in it water can get inside, freeze and expand. Just like freezing cracks large boulders.

Crackpots? How did I become the subject of this thread?

This is the first year that it happened to me...Most of my pots came from Matt also.
