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

The heat isn’t the issue, the detergent is. Ceramic absorbs water very easily, including the detergent. But detergent isn’t fit for consumption, yet it would leech out into your drink.
