My mom's cracked 1970s diner mug kept leaking on my desk until I tried a cheap food-safe fix from a pottery guy in Akron
That mug has a hairline crack running right down one side and it would sweat coffee onto my keyboard every single morning. I tried superglue first and it held for like 2 days before it let go again. Then a potter at a booth in Akron told me to stop using glue and try food-safe epoxy putty pushed into the crack from the outside, then sanded smooth after it cured. He said the key was warming the mug in hot tap water first so the crack opens up a hair and the putty goes deeper. I did that and let it sit for a full 24 hours and it has been dry for 3 weeks now. It is not pretty, there is a little gray line where the putty sits, but my desk is dry and I still get to drink out of her mug. Has anyone else tried the warm-it-first trick, and did the putty hold up longer than a couple months for you?
