Loctite Glass Glue is a type of super glue that can bond glass to glass. Regular adhesives do not create this type of glass on glass bond.
This glue creates a waterproof bond, is dishwasher safe, and establishes bonds so quickly that the pieces can be held together instead of using a clamp. This type of glass glue won't, however, stand up to high heat, so don't use it on anything that needs to go in the microwave. Also, the droplets of glue will not fill gaps, so use this type of adhesive only on pieces of glass that fit flush together.
