My coffee table glass top cracked when moving. Since the tables are over 30 years old, I didn't want to spend money on a refurbishment. But since small children often visit me, the sharp edge where it cracked was dangerous and was certainly one of their favorite toys. several hours of hardening trying to center the glass on the table. I bought Gorilla Glue and it fixed the glass table and has held up for over a month now. I also used this to fix a ceramic teaspoon handle that cracked in half. The communication even holds up in hot tea or in the dishwasher.
