Can porcelain break in the cold?

Yes, porcelain can break in the cold, particularly if it is exposed to sudden temperature changes. Rapid cooling can cause thermal shock, leading to cracks or breakage. Additionally, if porcelain has any imperfections or pre-existing weaknesses, the cold can exacerbate these issues, increasing the likelihood of breakage. To minimize risk, it's best to avoid exposing porcelain items to extreme temperature fluctuations.
