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? 🤷🏻‍♀️

It’s not the ceramic that you risk breaking, but rather the finish that is of concern. Putting delicate paints and finishes in the dishwasher is all but guaranteed to scratch and ruin their costing.
