Cyanoacrylate cement (Superglue, Instant Glue) is a very clear, strong, fast curing adhesive that will make barely noticeable repairs on glass objects, especially with clean breaks. The surfaces must be clean and grease-free for best bonding. Since the cement cures rapidly you must be able to press the parts together quickly and accurately and hold them in place for a few minutes. Allow overnight for full strength. Excess cement can be carefully scraped off the glass if any has escaped from the joint.
