Can I wipe a glass bowl that held warm food right away with a wet dishcloth?
After using glassware, while heat still remains, you may wonder if it is okay to apply a wet dishcloth immediately when clearing the table or rushing to tidy up. We aim to examine how sudden temperature changes strain tableware in everyday care situations.
Touching a glass bowl that still retains heat with a wet cloth or suddenly placing it in a cold place can cause it to crack due to the temperature difference, so it should be avoided.
Sudden cooling refers to a phenomenon where the surface temperature of heated glass drops sharply upon contact with cold moisture or air. Because glass transfers heat relatively slowly, if the temperatures inside and outside change unevenly, it cannot withstand internal contraction and easily cracks.
For Ishizuka Glass glassware as well, gripping it with a wet cloth while hot or placing it in a location with low temperatures can cause it to crack due to sudden cooling [1]. While warmth remains, it is safe not to wipe it immediately with a wet dishcloth or let it touch a cold sink countertop, and to wait sufficiently until the heat slowly dissipates at room temperature.
hmmm, the trick to using clear, solid-looking glass for a long time is the consideration of first giving the dish time to cool down on its own, rather than the touch of wiping it down.

The specific temperature difference for thermal shock resistance that the glass can withstand without breaking has not yet been confirmed in official materials.
