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? 🤷🏻‍♀️

Answer 1

I took 4 quarters of ceramics in college. I absolutely loved it. Our instructor made sure all glazes were dishwasher and microwave safe. And did not allow any glaze that was not to be fired with students projects.
I can’t imagine many others doing differently.
