Sometimes no matter how carefully you wrap or package a sheet of glass, such as the glass for a picture frame, the corners get chipped. A chipped glass corner can be more than just an eyesore, it can be downright dangerous, if the corner is on a glass coffee table that people pass by every day. Luckily, you don't need to spring for a brand new sheet of glass; you can easily repair it yourself.
Blow on the chipped corner, making sure it's free of dust and debris. For small chips purchase a clear epoxy at a craft store. Simply dab dots of clear epoxy into the cracks and dents, filling them. Allow the epoxy to dry.
Purchase a glue that's specially made for glass, such as Loctite glue or a comparable product. Put on a pair of latex gloves. Move the glass piece directly in front of an open window, where there's plenty of sunlight.
Add a dot of glue to the chipped place that is half the size of the dent. Press the chipped piece onto the dent and hold in place for at least five minutes. Leave the piece of glass in the sun for at least two hours as the UV rays from the sun help bond this material.
Shave off any excess glue with a razor blade.
