It appears my pot didn't fare too well outdoors over the last winter in my experiment. The ceramic material itself survived numerous freezes and thaws, but the glazing on it separated from the pot in several areas.
This shows the worst of it where several inches separated and came off as a sheet.
This shows the cracks and the glaze starting to lift in the same area on the opposite side of the pot. The interior surface has developed numerous hairline cracks as well though those areas haven't separated yet.
I can't see this in any way being a defect in the printing/manufacturing process as the glaze looked fine when I first received it. The seperation is also not around any thin spots on the glaze like the corners, but rather started right in the middle of very solidly glazed areas. Shapeways lists this material as heat resistant, but i'm not sure if anyone has tested it out for freeze/thaw tolerance before. I still think this material can make a good small bonsai pot, but after my experiment I would recommend it only for indoor use on tropical species. I just wanted to share this information for anyone else who might be planning on using this material for cups, dishes, ice trays, etc that might see use in the freezer.
On the bright side I was inspired to take my original idea and go in a slightly different direction
