Eli5: Why shouldn’t you put home made ceramics (a mug, for example) through the dishwasher? If they can withstand the heat of a kiln, surely a dishwasher is fine?

Question

I mean, I put them through the dishwasher sometimes anyway, but I’m told I shouldn’t? 🤷🏻‍♀️

Its not the heat. The ceramic is hard but brittle. The concentrated jet spray hitting the wrong spot where there’s a micro-crack or any imperfection could break pieces off.
