I probably dodged this ceramic problem because I drink from borosilicate glass beakers. (Yes, I buy new, unused labware for cooking/drinking use.)

Are those not too fragile for daily use? A pint glass is so much thicker in comparison than a beaker.

Mechanically more fragile than soda glass, but tougher to temperature shock -- admittedly not that useful for drinking, considering regular mugs also don't often break with boiling water. Good for cooking though: just check out the people mourning these real borosilicate Pyrex measuring cups.

To me it's mostly about the aesthetics. I've broken one or two over five years, but they are just too charming to give up on… Light, holds plenty of liquid, and good for pouring from.

I'm an adult so it's fine. And it's like $10 if I break one, no big deal.

Oh yeah, the beaker doubles as my metric-only measuring cup for cooking. It only has millilitre markings, no fluid ounce or cups at all.

They use them daily in labs, why not at home. My home is closer to a lab than a pub. No drunk people or children allowed.
